 1.Description
YJS-525 are good for photo frame molding. It 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 reaction.

Note: This is a 100A:2B mix ratio product that must be measured by weight. The choosing of suitable hardness should be according to the size and pattern design of the products. If large products and therefore multiple-piece molds are needed by customers, silicone rubber with higher hardness will be required for the molds. Conversely, soft silicon is indispensable for molds with complicated pattern and delicate details. The amount of curing agent admixture depends on the actual need of customers. More will be added for speedy drying and fast release and less when otherwise.
