RTV Silicone rubber HY-638 for concrete casting

Usage: 

RTV Silicone rubber HY638 is most suitable for concrete castings, cement statue, concrete pavers, GRC cement products, etc. with the advantages of good tensile strength, high tear strength, high temperature resistance, high duplication times and repeated use, etc. 

It is suitable for large products with detailed pattern, which is difficult to demould. 

This silicone rubber is one of the products with the highest use level in the production of concrete castings.

Description:

RTV-2 molding silicon rubber and silicone rubber are general called two-component room temperature vulcanization silicone rubber with excellent fluidity and good operational performance. 

Add curing agent of 2%~3% at the room temperature, the silicone rubber is still operational within 30 minutes, and in 2-3 hours, an elastic silicon mold will be obtained with resistance to deformation, high-temperature, acid and alkali and expansion. 

Operation instruction for RTV-2 silicone rubber HY638#:

The product is white or red flowing liquid with general hardness of 22~50 shore A after curing. 

If the customer wants to make large products and large size molds, the mold should be made of silicone rubber with high hardness. 

On the contrary, if the mold with fine and precision patterns, it should be made of silicon with low hardness. 

The amount of the curing agent depends on the actual requirements of the customer. 

If molds requiring fast drying and demould, more curing agent is needed; contrarily, if molds requiring slower drying and demould, less curing agent is needed.
