liquid silicone rubber for gypsum products molding
Application of liquid ( RTV-2) silicone rubber for gypsum products molding
Liquid ( RTV-2) silicone rubber for gypsum products molding is mainly applicable to gypsum products, plaster,resin, cements mold is good for casting Plasters, Cements and resin, toy craftworks, gifts and stationery, large statues, duplication of cultural relics mold making, etc.
Description of liquid silicone rubber for gypsum products molding
liquid ( RTV-2) silicone rubber for gypsum products molding is flowing liquid with consistant quality in whatever color. It consists of two components, wherein component A is silicone rubber, and component B is curing agent or vulcanizing agent. Firstly process and prepare the model mold or the product to be duplicated, take certain amount of the silicone rubber, add 2-3% curing agent, and mix evenly for use. One mold pair can be solidified and formed in 2-3 hours. The formed mold can be used repeatedly without deformation and water shrinkage and with high temperature resistance, thereby providing fast duplication of the product with a product shrinkage 2. The 618 manual mold silicon is mainly applicable to manual molds and small number of product duplication.
Operation Instruction of liquid silicone rubber for gypsum products molding
1. liquid ( RTV-2) silicone rubber for gypsum products molding is applied to small products or products with fine patterns. The mold for the fine detailed and small products should be made of soft silicon to protect the products from easy breaking when demoulding.
2. If large product duplication or fabrication, the mold should be made of higher hardness silicone rubber so that the products made will not deform.
