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.
Silicone rubber surfactant (Organic silicone surface additive) Application:
It can be used as a spray modifier, foliar absorption aids, activation agent, widely used herbicide, liquid nutrients, growth regulators, insecticides, fungicides, which do not decompose the original pesticide, can greatly reduce the surface tension of the solution, reducing the contact between the droplet and the leaf angle, surface enhanced the liquid in the plant or pest surface wetting, adhesion, and a spreader, thereby improving efficacy.
Silicone surfactant ZINCA-2000 is lower phytotoxicity and environmental hazards than the normal fatty amines, ethoxylated alcohol surfactant, and greatly reduce human and environmental impact.
Silicon rubber HY-638 application:
Silicon RTV (HY-638 ) is two parts condensation liquid silicone rubber that can be cure under room temperature. silicon rubber mainly used for the manufacturer of products made of unsaturated resin, epoxy resin, polyurethane, etc.
Silicon rubber(HY-638) features:
HY-638# silicon rubber is mainly with the advantages of good tensile strength, high tear strength, high temperature resistance, high duplication times and repeated use, etc. silicon rubber(HY-638) is the most suitable for small products or fine and precision products which is difficult to demould. This silicon rubber is one of the products with the highest use level in the production of craftwork gifts and the shrinkage less than 0.2%
Applications of rtv-2 silicone rubber
Rtv- silicone rubber is mainly be used as following:
1.Decoration building mould making, including architecture column, porch column, interior column etc
2.Unsaturated rein crafts, epoxy resin crafts, poly resin crafts, plastic toys and so on.
3.Concrete decoration, garden statue, plant, sculpture, buddha and animal crafts.
Introduction of rtv-2 silicone rubber
Rtv-2 silicone rubber for molding are generally named two part room-temperature valcanizatoin silicone rubber, a kind elastic silicone rubber mold which features good resistance to deformation, good durability
Features of rtv-2 silicone rubber
1 .Two part of rtv-2 silicone rubber: liquid white silicone and curing agent.
2. Cure at room-temperature within 4-8 hours, but all performance will act perfectly when it cure within 24 hours.
3 .Good fluidity and excellent operation.
4 .Good resistance to weather, temperature, aging, acid.
5 .Excellent tear strength, comfortable duplication times.
Brief description:
Silicone rubber for mold making:
1. Resistance to deformation, high-temperature
2. High reproduction times
3. Good tensile strength
4. Exceptional fluidity and good operability.

RTV-2 silicone rubber application
RTV-2 silicone rubber is mainly applicable to make the silicone mould for cultural relic duplication,architectural decoration, resin crafts, lighting ornaments, candles, statues, model design, product exploitation, etc.
[2] RTV-2 silicone rubber features :
RTV-2 silicone rubber, silicon rubber are generally named two -component room temperature vulcanization silicone rubber, a kind elastic silicone rubber mold which features with resistance to deformation, high-temperature, acid-alkali and expansion
[3] How to choose RTV2 silicone rubber for mold making :
Mainly be used for making various mold which features detailed pattern crafts, plastic , resin products and so on.
white, the usage for poly crafts, lighting and candles ,molds in multiple pieces for large products.
white, the usage for poly crafts, lighting and candles, multiple piece molds for large product .
[4]RTV-2 silicone rubber instruction:
RTV-2 silicone rubber are generally named as two-part room temperature sulfurated silicone rubber, which features an exceptional fluidity and good operability. When mixed with 2-3% curing agent, they can still be operated within 30 minutes, but will be formed after 2-3 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 poli crafts, resin crafts lighting and candle crafts.
Applications of RTV silicon rubber:
Silicone rubber is mainly applicable to manual mold design, PVC plastic molds, cement product molds, melting point alloy molds, alloy toy craftworks, plastic toy craftworks, gifts and stationery, large statues, duplication of cultural relics, shoe sole mold fabrication, pad printing positioning, shock resistance for electronic equipments, etc
Features of RTV silicone rubber
1. Good characteristics of easy-operation
2. Light viscosity and good flowability
3. Low shrinkage
4. Favorable tension
5. No deformation
6. Favorable hardness
7. High temperature resistance, acid and alkali-resistance and ageing resistance
Why should the silicone mold be reused only for a few times?
It can be due to the following reasons:
a. Adding too much silicone oil in to silicon rubber.
b. Using the silicon rubber with a high hardness to make molds for small sized products with delicate and intricate designs .
