Good Price Condensation Cure 2 Parts Rtv Silicone Rubber for
Moulding
1.Description:
YJS-520 is a high tear strength, tin-catalyzed RTV-2 silicone rubber, which was designed for casting polyester parts. It offers the same advantages of lower viscosity. YJS-520 is especially good for molds with deep undercuts and for molds that require flexing for part removal. YJS-520 is not sensitive to inhibition, meaning it will cure at room temperature over virtually any surface. It is easy to mix and de-air, and will cure with only a slight degree of shrinkage. The speed at which the rubber hardens can be accelerated with special activators. Condensation cure two-component silicone rubbers are excellent for most general mold making and prototype applications. They are excellent for casting waxes, gypsum, epoxies and other plastics. YJS-520 is extremely useful for those applications where superior elongation and medium durometer are required.
