Ddition cure rtv2 liquid silicone for making mold

 

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
