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.

Nitrile butadiene rubber, also known as nitrile rubber , NBR, Buna-N, and acrylonitrile butadiene rubber, is a synthetic rubber
derived from acrylonitrile (ACN) and butadiene.

Free sample rtv2 mould making silicone rubber for Architectural Molding
Architectural Molding Silicone
Product No.: C-825 and C-830 
Brand: GuoChuang Silicone 
Application: Making molds for brackets, panels, cornice moulding, statuary etc. 
Keyword: mold making silicone rubber, rtv2 silicone rubber, liquid silicone rubber,s liquid silicone for molding
1. Description
Architectural Reproduction and Restoration specialists use GC liquid mold silicone rubbers to make site molds of aging/damaged ornate architectural elements (e.g., brackets, panels, cornice moulding, statuary). From these molds, reproductions of damaged elements can be cast in the controlled environment of a mold shop. These imperfect castings are resculpted to their original beauty so a rubber production mold can be made from this revised model. This production mold allows repeated casting of the new architectural element in concrete, glass fiber reinforced concrete, plaster, plastic, fiberglass, or other casting media as required for interior or exterior mounting.
C-825/C-830 room-temperature curing silicone rubber are popular mold materials for this application and are available in pourable, brushable and sprayable options.
C-825/C-830 is A tin-cured silicone rubber with a 100A:3B mix ratio (digital scale required to measure) and a demold time of 3-4 hours. Tin-cured silicones are slightly less expensive than platinum-cured silicones, but have a shorter library life and shrink slightly on cure.

3. Liquid silicone rubber is intend forartificial fossils factory, europe component factory, simulation landscapes, animals and plants sculpture, sandstone crafts and so on.

2. Features of liquid silicone rubber:
Liquid silicone rubber is white or red flowing liquid with general hardness of 22-50 after curing with features -
(1)high tensile & tear strength
(2) high duplication times
(3) low linear shrinkage
(4) resistance to high-temperature
(5) resistance to deformation
(6)resistance to acid-alkali and expansion

3.Tips for liquid silicone rubber :
1. Weigh the liquid silicone rubber and curing agent exactly .
2. Stir the liquid silicone rubber and curing agent evenly .
3.We should choose the right hardness to making different size of product mold.
