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.

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.

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.

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.

1. Description
C-825/C-830/C-835 Silicone Rubber is a two-part, tin-catalyzed, liquid silicone system that cures (RTV) to a white, Shore A25-A35 rubber. This is a pourable rubber, but it can be easily thickened with Liquid Thickener or for brush-on application.
Popular product options is C-825/C-830/C-835 are the mold material of choice for high-volume veneer stone production (manual or automated manufacturing). These two-component mold rubbers capture excellent surface detail, offer exceptional dimensional stability and have unmatched lifetime and durability compared to hot melt and polypropylene systems.
Molds made from these room temperature curing systems can be completed in a much shorter timeframe (~4 hour demold) compared to latex rubber molds. When properly maintained, these molds can last for years and produce thousands of stones.
