the product belongs to PVC stabilizer and lubricant, without sulphuret; 2, Polypropylene and polyethylene as halogen absorbent can eliminate remained accelerant, without bad influence on the color and stabilization of the resin;3, used as the lubricant and demoulding agent of methbond, amido etc thermoset platics, the water-proof agent of the textile, and the flatting agent of the paint etc.
good fineness, dispersibility, top thermal stability, lubricity, light stability and innocuity, non-sulphuret, good transparency; It acts as the lubrication and its formulation has strong adaptability.
It is a kind of natural resin, amixture with various organic acid, and with special chemical activity, an important chemicals for paper-making, soap, ink, paint, rubber, sythetic resin, electric, insulating material, organic synthesis.
Road marking paints made from gum rosin, high molecular polymer, unsaturated dibasic acid and polyalcohol by condensation and esterification,then heat-stabilizer and light-stabilizer are added in. They are irregular hemisphere particals. which have good resistance to crushing, resistance to crocking, abrasion resistance, appropriate levelling and fast drying. They also have good resistance to yellowing and ageing resistance. They are used as a binder specially for road marking paints.
The above resins are irregular transparent solid which are the products of esterification by pentaerythrite and the adducts of rosin and maleic anhydride.For products heat-polymerized by the above resins and vegetable oils can be used in ester gums and phenolic paints; improve hardness of the paint films, gloss, rubbing property and buildiness for polyesters, nitro and PU paints; play as adhesive or binder for thermosol and road marking paints.
Pentaerythritol ester of gum rosin are made from gum rosin or light-colored rosin through esterification with pentaerythritol; used in adhesives,rubber products.
Glycerol ester of gum rosin are made from gum rosin or refined gum rosin through esterification with glycerol；Used in pressure sensitive adhesives,adhesives products.
