Product Overview

Tospearl 3120 is a 12 micron size micro-fine silicone resin that is used as an additive in biaxially oriented polypropylene (BOPP) films as a slip and antiblocking agent. As a slip agent it improves the Coefficient of Friction (COF) to facilitate easier processing, faster line speeds and prevents the film from tearing. 
Tospearl when used as a antiblocking agent prevents adhesion during film production both on a finished roll or on the inside of the bubble. 
In Paints & Inks Tospearl is used to improve moisture resistance, control viscosity and clarification of color, tone and gloss control.
