Description

Rosin, Fumarated, Polymer With Pentaerythritol, Calcium Salt is a chemically modified rosin derivative, specifically a calcium salt of a polymer formed from fumarated rosin and pentaerythritol. This compound is valued for its enhanced thermal stability, improved compatibility, and excellent film-forming properties compared to basic rosin esters. It serves as a critical performance additive in industrial formulations where durability and adhesion are paramount. Key industries that utilize this material include adhesives, coatings, inks, and polymer modification.

Application

• Hot-Melt Adhesives (HMA): Acts as a key tackifier and modifier, improving adhesion, open time, and thermal stability for packaging, woodworking, and non-woven applications.
• Industrial Coatings & Inks: Used as a resin modifier in solvent-based and solvent-free coatings and printing inks to enhance gloss, hardness, and pigment wetting.
• Polymer Compounding: Functions as a processing aid and compatibilizer in rubber and plastic formulations, improving flow properties and dispersion of fillers.
• Sealants & Caulks: Imparts flexibility, adhesion, and water resistance in construction and automotive sealant formulations.
• Pressure-Sensitive Adhesives (PSA): Modifies tack and peel strength in tapes and label adhesives.
• Foundry Binders: Used as a core binder component in sand casting processes for metalworking.
