ZELEC® and MERPOL® Alcohol Phosphates/Ethoxylates

ZELEC® and MERPOL® alcohol phosphates/ethoxylates are high-value liquid surfactants used as an internal mold release, antistat, or wetting agent in various polyester resin molding operations. They allow for continuous production processes such as prepregging and pultrusion, yield cleaner molds, and some grades can also improve the surface appearance of finished parts. Neutralized grades are available for customers concerned about the acidity effect on their equipment.
