1. Brief introduction of Liquid Silicone Rubber to Make Molds for Gypsum Cornice Molding

Liquid Silicone Rubber to Make Molds for Gypsum Cornice Molding is usually white flowing liquid in the hardness of 35 shore A with two parts, part A--silicone rubber, part B--tin cure silicone rubber. This kind of condensation cure silicone is with features of: 

 

(1) Liquid RTV Silicon for template with certificate approval

(2) 3% curing agent arrange together as free charged

(3) In liquid form and in various colors

(4) With an exceptional fluidity and good operability.

(5) Temperature and deformation resistance as well as low shrinkage.

(6) High duplication times

(7) Trial orders are available

 

2. Applications of Liquid Silicone Rubber to Make Molds for Gypsum Cornice Molding, XB-735#

XB-735# is with high hardness of 35 shore A and in high tensile and tear strength, which is suitable for very large size product with some pattern by brushing and pouring operation. Then the application of XB-735# would be used to make mould of the products in medium size such as 40~50cm with simple patters, such as the concrete/cement/stone products, plaster conics, concrete stamping, sculpture, gypsum decoration, plaster ornaments, fiberglass products, polyester decoration, and similar products .
