Description

Rosin, Fumarated, Polymer With Formaldehyde, Potassium Sodium Salt is a chemically modified rosin derivative, specifically a potassium sodium salt of a polymerized fumarated rosin-formaldehyde adduct. This specialized chemical offers enhanced thermal stability, improved compatibility, and excellent film-forming properties compared to basic rosin derivatives. It is primarily utilized in industrial formulations where robust performance and specific ionic characteristics are required, serving key sectors such as adhesives, coatings, and polymer modification.

Application

• Adhesive Formulations: Acts as a tackifier and modifier in hot-melt and pressure-sensitive adhesives, improving bond strength and thermal stability.
• Industrial Coatings & Inks: Used as a resin modifier in protective coatings, varnishes, and printing inks to enhance gloss, hardness, and drying properties.
• Paper Sizing: Employed in the paper industry for internal and surface sizing to improve water resistance and printability.
• Polymer Additive: Functions as a processing aid and compatibilizer in various polymer systems, including rubbers and plastics.
• Emulsifier & Dispersant: Serves as an emulsifying agent for synthetic rubbers (e.g., SBR, NBR) and as a dispersant in pigment and filler systems.
• Foundry Binders: Used in core and mold binders for metal casting due to its binding and thermal properties.
