High durometer silicone for Industrial Large Scale Applications,Architectural Restoration
Description of High durometer silicone for Industrial Large Scale Applications,Architectural Restoration:
Silastic RTV Silicone, also called condensation cure silicone, are two- component materials which
Cure at room temperature(RTV) to flexible, high tear-strength rubbers, Tin cured silicone can be poured onto models or they can be made brushable by adding a thixotropic additive. They are ideal for molds where easy release or high temperature resistance(Max 200 C) is required.
High Performance Silastic RTV Silicone can be used for casting polyurethane, epoxy, polyester resin, PU resin, cement, plaster, gypsum, candle, soap, waxes, toys crafts, poly resin crafts, Lighting, plastic toys, stationery gifts, statue, relieve furniture, furniture decorative materials, artificial stone, building decoration material, sculpture, sandstone, low melt alloys/metals, urethane, expoxy and so on.
High Performance Silastic RTV Silicone for molding is white or translucent flowing liquid with general hardness of 22-50shore A after curing. Molding silicone rubber is a kind elastic silicone rubber mold which features with resistance to deformation, high-temperature, acid-alkali and expansion as well as high reproduction times, good tensile strength, tear strength and elongation, Stripping the gender is good, Linear shrinkage rate low, Size stability is good.
FAQ of High durometer silicone for Industrial Large Scale Applications,Architectural Restoration
Why should the silicone mold be reused only for a few times?
It can be due to the following reasons:
A. Adding too much silicone oil in to silicone rubber.
B. Using the silicone rubber with a high hardness to make molds for small sized products With delicate and intricate design.
