1. Description
YJS-620 is a two-component 1:1 Mix addition (platinum) cured RTV silicone rubber which cures at room temperature. Because of its considerable fluidity, it is recommended for the duplication of models with many undercuts. This stuff is really thin and easy to pour.
2. Features
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
