YJS-630 is a harder material, with a 30A Shore hardness. It is recommended for in the manufacture of flexible molds for casting wax, gypsum, resins, concrete and other materials
YJS-630 is a two-component 1:1 Mix addition (platinum) cured RTV silicone rubber which cures at room temperature. YJS-630 is a harder material, with a 30A Shore hardness. Because of its relatively low viscosities and strong strength, it is recommended for in the manufacture of flexible molds for casting wax, gypsum, resins, concrete and other materials
*high chemical resistance to the aggressive components of some types of resin
*High resistance to laceration (this characteristic guarantees high resistance to wear and tear)
*High level of accuracy in reproducing very small particulars
*High dimensional stability over time and non-deformability
*Considerable resistance to high temperatures and to ageing
*Excellent non-stick effect
*Soft, stretchy, high tear resistance,
*Will not shrink in service
PLATINUM CURE for HIGH PRECISION Jewelery; Art; Industrial & Architectural molds — Highest quality in the world. Room temp cure TIME OF ABOUT 2 Hours.
Shore hardness of 30A – Will not shrink in service.
3. Common uses of YJS-630 Platinum Cure Silicone:
