Resin Crafts Mold Silicone Rubber

DESCRIPTION
        Resin crafts mold silicone rubber is also named the appropriative resin crafts mold silicone rubber, which includes condensation cure silicone rubber and addition cure silicone rubber, part A is flowable liquid silicone, part B is vulcanizing agent,they can be quickly formed after mixing,it is easy to operate. 
 

APPLICATION
        Resin crafts mold silicone rubber is intended for large, medium and small size products mold making and the products with detailed or intricate pattern, such as mold making of poly resin crafts, epoxy, Pu resin, lighting, candle, handmade soap, etc.  


FEATURES
        1.High temperature resistance,generally the temperature can reach 180-300 ℃.if special reagents are added,the silicone will be higher-temperature.Due to unsaturated resin will release a lot of heat when curing,it is easy to destroy silicone moulds.Therefore,the advantage of Hong Ye silicone rubber is higher-temperature,it can save much cost.

        2.The viscosity,hardness after curing,operation time,curing time and color of liquid silicone rubber are available on the basis of your requirements.

        3.Low shrinkage,the shrinkage of condensation type is less than 0.3%,and the shrinkage of addition cure type is less than 0.1%.

        4.Good tensile and tear strength,non-deformation,durable,high duplication times.  



USING INSTRUCTIONS
        1.Using the liquid silicone rubber with high hardness for large size products,such as split mould. On the contrary, for detailed small size products with intricate patterns, using the liquid silicone rubber with low hardness, such as envelope.

        2. If you choose tin cure silicone rubber, the amount of catalyst you add depends on your requirements.if you want to dry and demould quickly,adding more catalyst.On the contrary, if you want to demould slowly, adding less catalyst. (the amount of catalyst you add should be less than 5%)  


Silicone Rubber and Curing agent Reaction of Tin Cure Silicone Rubber
1.The amount of curing agent is 1%,mixture is still flowable in 2.5 hours,demould after 6-8 hours.
2.The amount of curing agent is 2%,mixture is still flowable in 50-60 minutes,demould after 2-3hours.
3.The amount of curing agent is 3%,mixture is still flowable in 28-30 minutes,demould after 1.5-2 hours.
4.The amount of curing agent is 4%,mixture is still flowable in 10-15 minutes,demould after 1-1.5 hours.
