Description
Properties:
Outstanding pressure sensitivity and adhesiveness. Great
sensitivity to heat, light, oxygen; Easily oxidized in powdery
state.
Solubility: Soluble in ethane, diethyl ether, acetone, benzol,
carbon disulfide, turpertine, aqueous alkali; Insoluble in
water.
Usage:
1. In Adhesive Industry: : Rubber based adhesive, synthetic resin
based adhesive and vegetable adhesive all have rosin as one of
their ingredients.
2. In the paint industry: : Rosin as a natural resin with abundant
sources, is easily dried and smooth on its surface. It will
continuously be the basic raw material for paint producing.
3. In printing ink industry: Rosin is mainly used as color carrier
of the ink and to increase its adhesion to paper. Without rosin in
the ink, the presswork will be blurred.
4. In the Paper making Industry: Sizing agent made from rosin can
prevent ink from dispersion, improve the strength and smoothness
and enhance abrasion resistant of the paper.
5. In the rubber industry: Rosin is used as a softening agent to
make the rubber soft and easy for kneading, make the filling agent
easily dispersed.
6. Other industries: Soup-making, coating, , food, building
material, scaling powder, musical instrument. Soldering fluxes,
soda, , and sealing wax.
Package: Packing in galvanized steel drum, N. W: **5KG/drum
