    Silicone Release Agents

    Ultralease

    Intro

    Class-leading Silicone Release Technology

    We have been working with silicone release agents for over 70 years for one simple reason: they work. Able to release a broad range of materials, be easily applied with no special training, and be incorporated into many processes, silicone-based release agents offer unmatched versatility and performance in an economical package.

    Ultralease is the latest iteration of our class-leading silicone mold release. Ultralease takes advantage of the tried and true performance of silicone and the fast evaporation rate of organic solvents to provide a highly effective and efficient release agent that will save you time and money with every cycle. Choose Ultralease for proven chemistry, ease-of-use, high-volume applications, or when cost is a limiting factor.

    Why choose Ultralease silicone mold releases?

    —

    Superior Release Efficiency

    Our Ultralease line of silicone mold release sprays and liquids feature extremely low-surface tension, which leads to excellent spreading (or wetting) properties. When lightly sprayed or wiped onto the mold, Ultralease products will form a very-thin, uniform film over the entire surface of the mold, even when applied in very low amounts. Because Ultralease silicone release agents provide complete coverage with a minimal amount of product, less release is needed per operation and build-up on the mold itself is minimized, resulting in more economical operation and less downtime.

    Broad compatibility

    Ultralease silicone mold releases have been engineered as broad-based solutions compatible with a range of materials and processes. All Ultralease products are chemically inert, allowing them to be used in varying environmental conditions, and ideal for sensitive materials such as polyurethane. High-thermal stability prevents the releases from breaking down under heat, making them efficient parting films for high-temp molding operations such as rotational molding and die casting. Aerosol and liquid formulations with variable dilution rates further add to the flexibility of Ultralease releases. For manufacturers who use varying materials or processes, this allows for simplified selection and easier incorporation into most molding processes.

    Higher Worker Safety Standards

    Ultralease silicone release agents utilize organic solvent carriers, for near-instantaneous evaporation and a quick cure-time. Many of our products are available in a range of solvents, from low-VOC to non-flammable to economically-minded options, allowing customers to choose the right formulation for their needs. Ultralease silicone mold releases benchmark against CARB standards for all of our products, ensuring that they are compliant to even the most stringent safety and environmental requirements. We are proud to carry the broadest line of non-flammable releases in the industry, and continue to work to maximize both productivity and worker safety with all of our products.

    Lowest Cost per Release

    Our silicone-based release agents are ideal for manufacturers looking for a highly efficient and economical solution to their molding challenges. Easily applied with no special training, Ultralease silicone mold releases feature high-thermal stability for exceptionally low in in-mold buildup/mold fouling, reducing the need for costly and time-intensive cleaning. Repeated use has been proven to seal and protect new molds and increase the lubricity of seasoned ones, providing extended protection and reducing downtime. Ultralease mold release exhibits a highly-efficient release rate, leading to a reduction in overall scrap when compared to other releases. The result is higher productivity and profitability through reduced downtimes, lower reject rates, and higher quality products.
