Note: This is a 100A:3B mix ratio product that must be measured by weight. The choosing of suitable hardness should be according to the size and pattern design of the products. If large products and therefore multiple-piece molds are needed by customers, silicone rubber with higher hardness will be required for the molds. Conversely, soft silicon is indispensable for molds with complicated pattern and delicate details. The amount of curing agent admixture depends on the actual need of customers. More will be added for speedy drying and fast release and less when otherwise.

Introduction of rtv 2 molding silicone rubber: 1. Two-part of rtv 2 molding silicone rubber: flowable liquid silicon and catalyst. 2. Rtv 2 molding silicone rubber cures at room temperature within 4-6 hours. Features of rtv 2 molding silicone rubber: 1. Rtv 2 molding siliconerubber has an exceptional fluidity and good operability. 2. Rtv 2 molding silicone rubber hasgood temperature and deformation resistance as well as low shrinkage. 3. Rtv 2 molding siliconerubber has high duplication times. Operation step for rtv 2 molding silicone rubber: 1. Step one to use rtv 2molding silicone rubber: take 100g of part a and add 2g of part b and mix thesilicon rubber and the curing agent evenly. 2. Step two to use rtv 2molding silicone rubber: vacuum pumping 3. Without exception, thistakes less than 10 minutes. Otherwise, it will cause cross linking reaction, and no more further steps will be available. 4. Step three to use rtv 2molding silicone rubber: brushing cast & perfusion molding operation. 25kgs/drum vacuum package or 200kgs/drum
Silicone rubber with vacuum casting Silicone Rubber Molding,China Silicone rubber with vacuum casting Mold silicone, specially used for large-scale reproduction of resin, ceramic, plastic, gypsum, cement, candle, soap and other crafts, with high number of times of mold overturn, long service life of the mold, resistance to burning and high temperature, strong resistance to tearing. First, crafts mold silicone use crafts mold silicone, specializing in resin, ceramics, plastics, plaster, cement, candles, soap, lighting and other handicrafts mass reproduction, addition molding and condensation type are suitable for handicraft mold, is an RTV Curing silicone rubber at room temperature. Second, resin crafts mold silicone advantage
Tin-based silicones, also called condensation-cure silicones, are two-component materials which cure at room temperature(RTV)to flexible, high tear-strength rubbers. Tin cured silicones can be poured onto models or they can be made brushable by adding a thixotropic additive. They are ideal for molds where easy release or high temperature resistance is required. Tin cured silicones can be used for casting polyurethane, epoxy and polyester resins, waxes, all gypsum products and low-temperature metals. Our tin-cured silicone systems are the most economical. They are best used for casting resins and low melt metals.
corrugated silicone tube is widely used in medical industry, it is able to withstand high temperature like autoclave sterilization. silicone is a good material to pass the medical test like bio-compatibility test.
High quality silicone foam tube for medical, consumer and industrial application. It has outstanding heat-resistant air aging performance, strong sealing, ozone resistance, and is moisture-proof.

Various properties about excellent liquidity, good work-ability, good tensile?force, with no deformation, heat resistant, acid and alkali resistant. Can be used repetitively. 2.Specification Silica gel is mixed with curing agent, the appearance of molding silica gel is liquid, A substitutes silica gel, B substitutes curing agent. For example, 100g A add 2g curing agent, but it needs to note, A and B must be mixed averagely, if not, the molding will not cure completely, and heterogeneous silica gel can affect its life time and result in that the molding will be completely scrapped. Packaging by airtight polyethylene drum.
Manual molding silicone rubber is mainly used for model design of manual mold, pvc plastic molds, cement products, low melting point alloy molds, alloy toys, plastic toys, handicrafts, stationery, large-scale sculpture, reproduction of cultural relic, shoe sole molds, pad printing allocation, electronic equipment antivibration, etc. 25kg/drum and 200kg/drum
