COAD 21 Zinc Stearate (Clear Melt) is a high purity zinc stearate with excellent melt clarity and specifically developed for the polymer industry.
In addition, its high purity ensures a superior heat stability to prevent haze and discoloration in unpigmented polymers.
Polystyrene: COAD 21 Zinc Stearate (Clear Melt) is used as a lubricant and mold release agent in unpigmented crystalline and impact polystyrene compounds.
Thermoset Molding: COAD 21 Zinc Stearate (Clear Melt) is an excellent mold release agent for phenolic, melamine, urea-formaldehyde, and other thermoset molding compounds where a heat stable material is required. |
