RTV Liquid Silicon Rubber Series
RTV-2 Room Temperature Silicon Rubber 
Model Code--HY-625#
Usage: Silicon rubber for PU/poly resin products, unsaturated resin products, plaster products, candles and gypsums crafts, toys, soap molds, statues,casting molds making, etc.
Users Instructions
RTV—2 molding silicone rubber (silicon) and silicon are generally named as two-part room temperature sulfurated silicone rubber, which features an exceptional fluidity and good operability．When mixed with 4％一5％ curing agent, they can still be operated within 40~70 minutes, but it will be formed after 4-5 hours．With resistance to deformation, high temperature, acid and alkali, and expansion, silicon flexible molds are used for mold duplication and delicate mold making for poly crafts, resin crafts lighting and candle crafts.
This product is a white or red flowable liquid with a hardness of 22—25 shore A° when it gets cured. For molds making of large-sized products, multiple-piece molding methods is required. Meanwhile you will need silicon rubber with a higher hardness. Conversely, soft silicon is indispensable for molds with complicated patterns and delicate details. The amount of curing agent admixture depends on your requirements. Pls add more for a speedy drying process and a fast releasing and less on the other hand.(Notes：Normally we do not recommend  you to add any silicon oil. For special soft mold or molds with complex pattern or fine details, 5％一10％ silicon oil can be added to condition the flexibility of the mold for convenience of release)

Mixing Ratio for Silicon Rubber & Curing Agent and the reaction time (Under room-temperature-25 0C)1、Added with 2％ of curing agent, silicon can      still flow within 80-100 minutes, mold can be released in 8-10 hours.2、Added with 3％ of curing agent, silicon can still flow within 60 to 85 minutes, mold can be released in 6-8 hours．3、Added with 4％ of curing agent, silicon can still flow within 45-65 minutes, mold can be released in 4-6 hours.4、Added with 5％ of curing agent, silicon can still flow within 30-50 minutes, mold can be released in 2~4 hours.
