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
