Hight Hardness Silicone Rubber for Stone

High hardness silicone rubber for stone:

Operation instruction for RTV-2 plaster molding silicone:

the product is white or red flowing liquid with general hardness of 34-38 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 silicone 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.

(note: our company does not recommend you to add silicone oil.if a special soft silicone mold or fine detailed and complex patterns products are required,5%-10%silicone oil can be added to soften the mold for easy demould.)

General description:

RTV-2 plaster molding silicone and silicone rubber are general called two-component room temerature vulcanization silicone rubber with excellent flluidity and good operational performance.add curing agent of 2%-3% at the room temperature,the plaster molding silicone is still operational within 20 minutes,and in 2-5 hours,an elastic silicone mold will be obtained with resistance to deformation,high-temperature,acid and alkali and expansion,the plaster molding silicone is mainly applicable to mold duplication of  poly crafts,resin craftworks,lightings,candles,etc,and fabrication of precision molds.
