Gum Rosin

タイトルまたは説明

1.It can be widely used in adhesives,paints,oil paints,rubber,soaps and paper making industries.

2.Rosin in hot melt, pressure sensitive adhesive and solvent is usually used for increase adhesion resin, early increase viscosity, improve the bonding strength. Rosin can still improve waterborne acrylic ester fumo plastic's dry and peel strength, best dosage monomer 6% of the total. Rosin is a weak acidity material, if SBS type all-purpose adhesive or spray adhesive dosage of too big, can cause iron from corrosion packing, the glue quickly become a palm black, although did not affect the adhesive ability, but the appearance but a doubt. Light, heat, oxygen rosin role is very sensitive, especially powder extremely easy oxidation, so good the whole piece of storage hoop, prevent oxidation make dark, performance changes. Massive rosin surface oxidation generated oxidation film, can prevent the internal rosin further oxidation. Wet oxidation process can accelerate rosin, depth when acetic acid oxidation released.
