ReleaseAgentsGENERAL QUESTIONS ABOUT RELEASE AGENTS

What are the advantages and disadvantages of silicone-freerelease agents compared to those containing silicone?
Silicone-based release agents:• Offer very good release properties and are usuallyadvantageous 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 necessaryprior to painting or gluing.
Why does the automotive industry almost exclusively use
silicone-free release agents?
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.
What happens if a release agent is over-applied?
Over-application can cause an oily or slick surface on themolded part thereby impeding subsequent process treatment of
the parts. Therefore, over-application should be avoided.

Are there suitable release agents for thermoplastic materials
that are sensitive to stress cracking?
Materials such as PC, PS, and PMMA are particularly sensitive
to stress cracking. Release agents have been developed that canbe used in the production of parts made from these materials.
What is the advantage of using release agents from aerosolcans instead of non-aerosol products?
The use of an aerosol can allows for a consistent, even, thin
application with a predictable spray pattern preventing overapplication. Spray offers easy handling.
How should non-aerosol release agent products be applied?
Non-aerosol products are best applied using a high-quality
spray gun or with clock-controlled spraying equipment.
What does the maximum application temperature of a releaseagent refer to?
The maximum application temperature refers to the moldsurface temperature until which the release agent is effective.
If applied to mold surface temperatures beyond the maximum
application temperature, the release agent will start todecompose and negatively impact the release properties it
was designed for. The maximum mold service temperature isdescribed in the PDS of the relevant product.
