Product Description
Rongxingda Tin cured Silicone Rubber is a two-component mold rubber that composed of Part A and Part B.Part A is liquid silicone rubber with white ,thick and sticky,and Part B is a tin catalyst with pale yellow liquid.When Part A and Part B are mixed thoroughly with the weight ratio of 100:2-100:4 ,they can cure at room temperature and the warmer temperature will cause them to cure faster,and the process of curing will not produce heat.The final product after curing is a flexible silicone material with high tenacity, in a hardness range of 5-40 Shore A available for making various molds.

Tips: 
1.The working time of RTV-2 silicone rubber indicates how long the material will remain fluid at 23℃~25℃。However work should be carried out in the shortest time,because viscosity increases with time. 2.Besides of temperature and humidity,the curing time of tin-cured silicone rubber is on the thickness of final molds. 3.The original color is white or translucent,but Part A can be added pigments for other colors needs. 4.The above conventional parameters can be customized.
