FAQs: Release Agents
Looking for answers about release agents for thermoplastics processing applications? Learn more about frequently asked questions and the answers you need.
Silicone-based release agents:
- Offer very good release properties and are usually advantageous for the manufacture of products with long cycle times.
- However, in most cases, additional post-mold operations will be necessary prior to painting or gluing.
Silicone-free release agents:
- Usually, no additional post-mold operations will be necessary prior to painting or gluing.
Parts produced for the automotive industry are generally subject to additional post-molding operations such as gluing, painting, or imprinting. The use of silicone-free release agents usually avoids any unnecessary non-value-adding workflow procedures.
Over-application can cause an oily or slick surface on the molded part thereby impeding subsequent process treatment of the parts. Therefore, over-application should be avoided.
Materials such as PC and ABS are particularly sensitive to stress cracking. Release agents have been developed that can be used in the production of parts made from these materials.
The use of an aerosol can allows for a consistent, even, thin application with a predictable spray pattern preventing overapplication. Spray offers easy handling.
Non-aerosol products are best applied using a high-quality spray gun or with clock-controlled spraying equipment.
The maximum application temperature refers to the mold surface temperature until which the release agent is effective. If applied to mold surface temperatures beyond the maximum application temperature, the release agent will start to decompose and negatively impact the release properties it was designed for. The maximum mold service temperature is described in the PDS of the relevant product.
Chem-Trend offers a wide range of different release agents for all kinds of thermoplastics materials, a variety of thermoplastic processes as well as different mold surface temperatures. Both silicone-free and silicone-based release agents are available.
