Acrylic formulation

Pouring art is so much fun! And we all make mistakes time after time and learn from them. I wish I could go back in time and share all these tips with myself at the beginning of my pouring journey, and it would save me so much time, paint, and effort. So I hope that you are going to learn something helpful and it will make your practice even more rewarding! When I just began my experiments with acrylic pour painting, I would always mix either too much or not enough paint.

There is no single opinion or strict rule about it, just like there is no sole opinion about how dense your mixture should be. So my answer would be — yes, but only when you actually need it. Even if you know the exact amount of water that you are going to need. The reason for that is that each painting has a different ability to absorb the water.

It helps to ensure the even dispersion of water in paint polymer.

Plus, by adding a little at the time, you are not taking the risk of accidentally adding too much and making the mixture too fluid. Dutch pour is an exception — for this technique, I like to add extra water to help paint follow the blow dryer airflow. I usually do 1 part of paint to 2. After the medium, I add a little distilled water when needed to get it to the right consistency. Unfortunately, even they fail time after time, not to mention Floetrol, that is technically not even a pouring medium.

So what can you do to prevent crazing? Crazing can happen when the top layer of the paint dries faster than the bottom layers. Keep your pours away from the draft.

Reduce the amount of water in your mixture as it can also cause crazing. Here is the best solution ever! I like to keep the reference picture or video from my phone in front of me while painting.

Unfortunately, it tends to create white lumps that are pretty annoying and noticeable on a dry pour. Simply stretch it over the bottleneck of Floetrol.Cookies help us deliver our services.

Optimized formulations.It is of utmost importance that the protective element hereinafter referred to, for convenience, as the lens of a COB-LED device remain optically transparent for an extended period of time; indeed, it is the durability of the lens that often determines the useful life of the device.

The cured resin must therefore resist degradation from exposure to radiation emitted from the LED itself and other causes, such as outdoor environmental effects. Unlike LED arrays used in calculator displays and the like, many potential applications for COB-LED devices require extraordinary brightness and entail the use of relatively high electrical currents.

The corresponding levels of heat generated often make temperature management a primary design and engineering consideration, and give rise to a need for a lens-forming resin that is capable of resisting high-temperature thermal degradation and distortion.

Attempts to use one-part, radiation-cured urethane, epoxy, and rubber acrylates, and formulas based on cationic epoxies and vinyl ethers, in the manufacture of COB-LED products have, as far as is known, been unsuccessful due to unacceptable degradation of the cured resins at elevated temperatures, over time.

Accordingly, it is a broad object of the present invention to provide a novel, non-aqueous and solvent-free formulation that cures to a transparent solid body of high optical clarity, which body exhibits outstanding resistance to thermal degradation and distortion, as well as to degradation from radiation and moisture exposure. A more specific object of the invention is to provide such a formulation that is especially adapted for the fabrication of bodies suitable for use as transparent protective elements and lenses for COB-LEDs and similar optoelectronic devices, particularly devices that operate at relatively high temperatures.

Further specific objects are to provide such formulations in a range of viscosities, adapted for fabrication by a variety of techniques, including direct application to a substrate in the form of a mechanically unconstrained dome, followed by irradiation to effect curing of the formulation; and to provide such formulations which cure rapidly upon exposure to suitable actinic radiation. Additional objects of the invention are to provide novel methods for the production of heat- and radiation-resistant transparent solid bodies, and optoelectronic devices comprised of such bodies, and to provide solid bodies and optoelectronic devices produced by such methods.

It has now been found that certain of the foregoing and related objects of the invention are attained by the provision of a formulation broadly comprised of about 10 to 40 and preferably at least 20 weight percent of a nonpolymerizing acidic acrylic resin, about 90 to 45 weight percent of a selected reactive diluent in which the resin is soluble, and an amount of a free-radical photoinitiator effective to initiate polymerization of the reactive diluent, the formulation being at least substantially free of water and solvents.

Albeit acrylate resin having a molecular weight as high asmay be useful in the present formulations, particularly when intended for use as encapsulants, coatings, adhesives, and the like, the molecular weight of the acrylic resin employed in a lens-forming formulation will usually not exceed 80,; indeed, for such applications the molecular weight of the resin will preferably be in the range 8,—12, and most desirably it will be about 9, to 10, In any event, the outstanding performance exhibited by the PB and PB products in the instant formulations is attributed to the presence of unreacted hydroxyl groups on the backbone of the acrylate monomer from which the resins are produced.

Although other monomers may be found suitable for use as the polymerizable reactive diluent in formulations embodying the invention, best results in order of decreasing preference are achieved using tetrahydrofuryl acrylate THFAN,N dimethyl acrylamide DMA2-hydroxyethyl methacrylate HEMAand hydroxybutyl acrylate HBA.

Hydroxypropyl acrylate HPAmethacrylates corresponding to the foregoing acrylate compounds, alkoxylated counterparts to the foregoing, other acrylates and acrylamides containing reactive hydroxy groups, and carbon and nitrogen-substituted analogs of the indicated acrylamides should also produce good results. Needless to say, mixtures of two or more of the designated compounds can constitute the polymerizable diluent of the formulation, as may be preferred.

It has been found that very few polymerizable monomers are effective to solublize acrylic resins sufficiently to produce clear liquids, and that even fewer such monomers, containing the dissolved acrylic resin, will cure to the optically clear, relatively thick bodies that are provided by the instant invention; indeed, as discussed below, a number of the most commonly employed reactive diluents are found to be unsatisfactory for present purposes. Moreover, solvent strength is not the sole criterion.

For example, while the use of DMA leads to formulations containing the highest concentrations of acrylic resin, THFA exhibits better thermal resistance when heated. While all free-radical photoinitiators that do not inherently impart color, or cause or promote degradation of the cured body after exposure to high temperature and radiation, are regarded to be suitable for use in the present formulations, preferred UV photoinitiators include 1-hydroxycyclohexyl phenyl ketone, 2-hydroxy-methylphenyl propanone, benzophenone, and methybenzolformate.

Conventional visible light-responsive photoinitiators may also be effective, and may be necessary when a UV-blocking dye or pigment has been included in the formulation.

Optional ingredients in the formulation include acidic adhesion promoters preferably crotonic acid, acrylic acid and methacrylic acidnormally used in a concentration of about 1. It might be noted that the outstanding performance of crotonic acid, as a particularly preferred adhesion promotor, is unexpected due to its relatively low reactivity as compared to the reaction rates of acrylate and methacrylate monomers.

Any cross-linking agent employed should itself be very clear and should of course be so selected as to not adversely affect clarity of the cured body or degradation therein over time or due to heat or other exposure.

It should be noted that dome elements e. A crosslinker can of course be incorporated to tailor the hardness of the cured body, and typically THFA-based formulations can cure to hardness values ranging from A to D depending upon the nature and amount of crosslinker added.Applied at thicknesses of 10—30 mils, fusion-bonded epoxies are the coating of choice in such demanding applications as oil, gas, and water pipelines.

Powder coatings have achieved a great deal of respect in the coatings world over the years. While powder coatings are also praised as being easy to use, achieving success in a powder coating operation is not nearly as easy as some might think.

There are many factors to take into consideration, but if you start with the big picture, you begin with cleaning, drying, coating, and curing.

Of course, zeroing in on and optimizing each of these areas is an undertaking that, as many successful coaters will tell you, requires time and effort. Selecting the right powder formulation is just one aspect of mastering the coating portion of that big picture.

Thermoset powder formulations are a blend of resins binder systemspigments, extenders, and other additives. Resins give the finished coating its physical properties, such as flexibility, chemical resistance, outdoor durability and hardness. Each resin has different properties, so the resin is chosen according to the end use of the powder coating. For example, the resin system used for architectural aluminum coatings would be different from those used to coat domestic appliances.

Pigments not only give the coating its color, they provide the ability of the coating to hide the metal. Different pigments have different hiding powers, so the amount of pigment used can vary significantly for different colors. Pigments also come in weatherable and non-weatherable versions. Last but not least, additives in coating formulations are used to alter the characteristics or physical performance of the coating, for example, gloss and texture.

They can also affect flow and coating durability due to their ability to withstand UV exposure.

Acrylic Roof Coatings 101

Another example is using slip agents or waxes to help reduce scratching and marring. A thorough understanding of the end use environment is critical to selecting the correct coating for your parts. Other characteristics to consider are gloss, orange peel, film thickness, salt spray resistance, heat resistance, smoothness, color, texture, substrate characteristics, and edge coverage, among others.

For example, cure ovens with short dwell times may require low-energy-cure powders. Other considerations involve part configuration—for example, parts with large variations in metal mass or parts with complex Faraday areas. Of the infinite array of coatings that can be imagined, and of the dozens of types that have been sold during the year history of powder coating manufacture, four reliable, cost-effective workhorses have emerged, especially within the North American market.

As mentioned earlier, each resin system will give specific properties to the coatings, making them suitable for different requirements. The chart shows the main advantages and disadvantages of each binder type. While rising costs have been pervasive, increases have been the greatest for epoxies.

In the last several years, polyesters have been applied more often, even on indoor applications, due to the rising cost of epoxies. The data reflects that switch more heavily in the use of epoxy-polyesters. Years ago, epoxy-polyesters were created to provide powders with greater overbake stability and ease of application compared to epoxies, which have very high hardness and chemical resistance.

Where those characteristics are not necessary, there can be some compromise. Polyesters provide more versatility for indoor or outdoor applications, making it cost-effective to switch over to the polyesters when the epoxy-polyesters increase in price. We are also seeing a decrease in urethane use.
