Mold Release Agents

Increase Your Productivity with Our Mold Release Agents



Mold release agents are a fundamental part of the manufacturing process, but they are rarely acknowledged for the value they create.


The right release agent can combat many common production challenges, including:


  • Sticking parts
  • Cracking
  • Buildup on parts and molds
  • Excess release transfer that impacts part appearance
  • Scrapped parts
  • Limited cycles

Removing these challenges increases uptime and overall productivity, reduces scrap cost, and eliminates many late shipments.
