UniSil develops platinum cured silicone with 1:1 mixing ratio specially for polyester molding. This type of silicone is with light viscosity, self bubble release. It is excellent molding materials for polyester resin, urethane resin, epoxy resin molding.

Special Feature: Anti-contamination from polyster resin, urethane resin, epoxy resin.

If you came accross the problem of platinum cured silicone get inhibited during making resins molds, this special type of silicone may help to you. Using this type of platinum cured silicone, there will be non-sticky on the both side of surface which in touch with resins and surface exposed in the air after cure.

Regular Features:

1. Stable dimension, non-shrinkage with time being;

2.High tensile strength, good aging resistance;

3.Human skin safe, No hazardous during application;

4.Low viscosity, easy self de-bubbles;

5. Anti-high temperature ;

6. Good flow-ability, easy to penetrate into complicated details.

Inhibition of Cure

All Addition-cure silicone rubber may be inhibited by certain contaminants in or on the pattern to be molded resulting in tackiness at the pattern interface or a total lack of cure throughout the mold. *Amines,tin cured silicone and sulphur containing materials (sulfur clays) are strong inhibitors. * some other materials like Latex, certain wood surfaces, newly cast polyester, epoxy, or urethane rubber also may cause inhibition.
