Overview
ZELEC® Acid Alcohol Phosphates are effective internal release agents for polyester molding operations and can be utilized as antistatic agents for coatings and plastics.
ZELEC® UN is effective as release agent in externally heat cured molding such as pultrusion, matched metal die, compression molding, sheet molding, and bulk molding.
ZELEC® UN has shown to be especially useful in pultrusion where it can reduce pull force, improve resin wet out, and maintain part integrity. ZELEC® UN can also be used as an antistatic agent if neutralized with KOH or an amine.
