Product Information

PVA release lacquer is also used to treat porous or sealed surfaces, such as melamine resin press plates, plaster or wood. Partall Film #10 is a water/alcohol-based polyvinyl alcohol (PVA) mold release agent that forms a barrier between parts and mold surfaces that are still curing (green or recently reconditioned molds can be reactive). Slide mold release agents are available as aerosol sprays and bulk liquids, in a variety of formulations for engineered resins, thermosets, epoxies, and deep draw molding. From light duty to heavy duty, food-grade and NSF-certified, medical part molding, paintable, non-silicone, specialty releases and mold releases for investment wax castings, Slide’s array of high-quality formulations ensures the best results for every application. Do not use silicone spray on painted surfaces. The paint tends to absorb the spray, making it very difficult to apply a new coat of paint over the silicone-infused layer.

PVA is most commonly applied over mold release wax although some users find success by adding wax over the PVA film (giving a second part cycle before replacing PVA.)This colorless, nonstaining silicone spray can be used on metal, glass, rubber, or plastic to help protect the material and extend the life of appliances. The 11-ounce can of silicone spray doesn’t come with a straw for the precision application, so users will only be able to spray broad surfaces or by bringing the can much closer to the target object. PVA release lacquer is often used in combination with a release wax for epoxy resin. It serves as the last layer between release wax and the epoxy resin. It not only ensures excellent demoldability, but also a high-gloss surface. PVA does not need to be polished after application. After demolding the casting, you can easily remove residues of the release lacquer with lukewarm water and a sponge.

In short the answer is no, It is not a necessity to use a mould release spray they can help on more difficult moulds of course but you can still get the same results without a spray Protects against mold hang ups with polyester and vinyl-ester resins; also used with epoxy and urethane resins Econo-Spray 1 Mold Release Agent Spray (40510P): an economical, food-grade, non-paintable, silicone oil-based mold release recognized by UL It normally takes just a few minutes for spray lubricants to dry but can take up to 24 hours to fully cure. Q. How do you clean off silicone spray? New forms should be treated in this way several times, preferably three times. After each spraying, allow the mold to flash off overnight.The spray works via a combination of wax and aerosols. The latter act as carrier material and apply the protective wax layer to the mold. While the wax layer remains on the mold, the aerosols evaporate within a short time. Silicone sprays normally contain about 1.5 percent silicone, but this can increase to 3.5 percent while still remaining a spray. High silicone sprays are best for lubricating heavily-used joints and machinery. You should also review the formula and the manufacturer’s recommendations to determine whether you can use silicone spray on certain metal, wood, plastic, or other materials. Food-Grade Always loosen the edges of the casting first. Most components can be released from the mold by this alone; simple components already slip out when you turn the mold over. Depending on the product, the effective temperature range can vary significantly, with some silicone sprays having minimum temperatures of -100 degrees Fahrenheit while others have high-temperature maximums that exceed 1,000 degrees Fahrenheit. If using the silicone spray on windows or doors, choose a product that will hold up to seasonal temperatures. Drying Time Silicone spray is used to properly lubricate metal, wood, rubber, and plastic while providing a water-resistant barrier. However, once a surface has been sprayed, it becomes difficult to paint, so you will want to plan out your projects before applying it to every exposed hinge. Q. Is silicone spray waterproof?
