Product Description

Good quality liquid silicone rubber for gypsum molds making

1.Product Description

YJS-525 is medium hardness silicone with hardness Shore A 25. It is a kind of of two- component materials

consisting of a flowable part A which when mixed with the curing agent or catalyst,cures at room temperature

by a condensation recation. It is widely used for resin, gypsum, concrete/cement and artificial stone molding.

2.Features

-Easy to demould

-Good resistance to tearing

-Good elastic

-Good tear&tensile strength

-Dimensional stability in time ( deformation - shrinking only up to 0.3 % )

-Remarkable resistance to high temperatures (up to 200 - 220℃ )

-Final curing at room temperature
