Description

Rosin, Fumarated, Polymer With Glycerol is a modified rosin ester produced by the polymerization of fumarated rosin with glycerol. This chemical modification enhances its thermal stability and compatibility, making it a valuable component in formulations requiring durable, tackifying, and film-forming properties. It is primarily sought after by manufacturers in the adhesives, coatings, and ink industries for its ability to improve product performance and longevity.

Application

• Hot-Melt Adhesives (HMAs): Acts as a key tackifier and viscosity modifier, providing excellent bonding strength and thermal stability for packaging, woodworking, and non-woven applications.
• Pressure-Sensitive Adhesives (PSAs): Enhances peel adhesion and tack for labels, tapes, and graphic films.
• Industrial and Protective Coatings: Used as a resin modifier to improve film hardness, gloss, and water resistance.
• Printing Inks: Serves as a resinous vehicle to enhance pigment wetting, print gloss, and rub resistance in publication and packaging inks.
• Polymer Modification: Functions as a processing aid and compatibilizer in various rubber and plastic compounds.
• Sealants and Caulks: Imparts flexibility, adhesion, and durability to construction and automotive sealant formulations.
