A Guide to selecting the right type of release agent
Price-Driscoll patented the first aerosol mold release in 1947, and has been a leader in the industry ever since. Over 70 years, we’ve developed a lot of products, ranging from economical, all-purpose releases to more advanced, specialty formulations. Use the guide below to understand our offerings, and help select the best type of release agents for your needs.
We provide multiple types of release agents, with varying durability, efficiency and transfer properties. Proper selection is critical for maximum performance.
Conventional (or sacrificial) mold release agents need to be applied every molding cycle. The workhorse of the industry, they are generally built-on silicone, wax or petroleum bases and are best suited as all-purpose releases for high volume or small, complex parts. During each cycle, a degree of the release will transfer to the molded part, and therefore may need to be cleaned off post-mold. Some conventional agents are more difficult to remove from parts than others, and may limit your ability to paint or bond post-mold. Conventional release agents are selected for their ease of use, effectiveness across a broad range of applications, and favorable economics.
The newest generation of release chemistry features a reactive or functional silicone that bonds with the mold’s surface (sometimes with the assistance of heat) to form an extremely durable parting film that provides multiple release cycles per application. Semi-permanent release agents can be sprayed, brushed or wiped on, and once cured, provide high surface slip and temperature stability up to 600°F. Many also function as a mold sealer at higher concentrations. Semi-permanent releases require more upfront investment than conventional releases, but return that time and money through their effectiveness and efficiency, particularly in more complex operations.
Blended release agents combine silicone with additional proprietary additives to combine the ease of use of a conventional release with some of the performance qualities of a semi-permanent. A single coat will rapidly cure at room temp, and allow for multiple releases in most operations. Blended release agents outperform conventional release agents at elevated temperatures, or for problem areas requiring a higher-degree of slip. Also included here is our popular line of Parfilms, which have been specifically formulated for use with epoxies, polyesters, urethane polymers. Choose blended releases for ease of use and elevated performance.
Non-silicone release agents provide the same high level of slip as our silicone-based products but without the oily residue, making them ideal for critical operations where a silicone oil can not be used due to possible contamination, regulatory restrictions, or a desire for post-mold operations such as painting or bonding. Our non-silicone release agents are high-purity and non-contaminating, with water-soluble, bio-degradable, and FDA compliant (21 CFR 172.880) options available. Applications include clean-room molding, electronics potting, food-safe processes, silicone molding and other critical operations where a silicone-release is not appropriate.
Many of our products are available in multiple formulations to help customers balance productivity, worker safety, and economics.
In support of providing products with unparalleled worker safety, Price-Driscoll continues to maintain the broadest selection of non-flammable mold releases in the industry. Our NF formulation utilizes a non-flammable propellant and non-flammable solvent suggested by the S.N.A.P. sector of the EPA. For use on steel molds only. Chose NF when you absolutely must have the lowest-flammability product on the market.
A new concept of solvent-less, low-VOC release agents engineered to be effective with the broadest possible range of materials. Release agent has a fast evaportation rate and provides a dry finish. Low-VOC formulation contains no chlorinated solvents, is non-ozone depleting with very low global warming potential. GP formulation supports our triple commitment to worker safety, environmental responsibility and business productivity.
S is our most economical offering, while still maintaining our high performance standards. Maintains the same performance characteristics of our other formulations, but uses a flammable hydrocarbon solvents and propellants to keep cost down. Contains no chlorinated solvents, is non-ozone depleting, and has virtually zero Global Warming Potential. Choose the “S” formulation when cost is the determinant factor.
Choose the tried and true chemistry of silicone-based Ultralease for most applications, or non-silicone Supralease for specialty needs.
Silicone-based, Solvent carrier
The Ultralease line of release agents takes advantage of the tried and true performance capabilities of silicone and the fast evaporation rate of solvents to provide a highly effective and efficient release agent suitable for most applications and materials. Conventional and semi-permanent formulations ideally suited for plastics, rubbers and polyurethanes, with food-safe, paintable and high-temperature options available. Ultralease is available in aerosol or liquid packaging, and with multiple propellant/solvent systems to provide maximum flexibility and meet a broad range of customer needs. Choose Ultralease for proven chemistry, ease-of-use, high-volume applications, or when cost is a limiting factor.
Silicone-free, specialty releases
A tailored line of specialized, silicone-free release agents for critical operations where a silicone oil would be inappropriate due to possible contamination, food-related processes, or a desire for post-mold operations such as painting or bonding. Supralease release agents provide the same high level of slip as our silicone-based products, with no oily residue. Applications include clean-room molding, electronics potting, food-safe processes and silicone molding. Supralease release agents are high-purity and non-contaminating, with water-soluble, bio-degradable, and FDA compliant (21 CFR 172.880) options available. Choose Supralease for critical operations where a silicone-release is not appropriate.
