Gum Rosin
Colophony Light Yellow Gum Rosin/ Colofonia
1. Molecular formula: C19H29COOH
CAS No.: 8050-09-7
Appearance: Light Yellow
2. Application:
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 Papermaking 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.
