Properties: a little bitter taste. Specific gravity: 1.50--1.59. Soluble in chloroform, toluene, benzene, carbon tetrachloride. Insoluble in water and ethyl alcohol.
Application: given flat, moderately fast cures in nr and sr. Also used in a wide range of general purpose rubber. Non-staining/non-discolouring in "white" socks; use as a plasticiser and/or retarder in polychloroprene rubber. Secondary acceleration is usually required for synth etic polymers. Better scorch safety than mbt.
Storage: keep container tightly closed in a cool, well-ventilated place. The recommended max. Storage life is 2 years when stored under normal conditions.

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.
Quality: Stable, Good elasticity and Flexibility, self-life over 12 months
Application: Agricultural, Industrial, Electronic, Household, Tie Money, Flower, Hair, Package and Food, etc. Can be used widely as gifts, decorations, mechanical equipment, making gloves, etc.
