Description

Rosin, Fumarated, Polymer With Formaldehyde, Glycerol, Nonylphenol And Pentaerythritol is a specialized, high-performance modified rosin resin designed for demanding industrial applications. This compound is engineered to provide superior adhesion, tack, and chemical resistance compared to standard rosin derivatives. It is a critical raw material for formulators in the adhesives, coatings, and ink industries seeking to enhance product performance and durability. The CAS number for this substance is 70248-44-1.

Application

This modified rosin resin is a versatile polymer additive prized for its excellent film-forming and binding properties. Key industrial applications include:

• Hot-Melt Adhesives: Acts as a primary tackifier and viscosity modifier, improving bonding strength and open time.
• Pressure-Sensitive Adhesives (PSAs): Enhances peel and shear strength for tapes, labels, and graphic films.
• Industrial Coatings & Inks: Used as a resin modifier to improve gloss, hardness, and pigment wetting in protective coatings and printing inks.
• Rubber Compounding: Functions as a processing aid and reinforcing agent, improving tack and dispersion of fillers.
• Sealants and Caulks: Provides improved adhesion to various substrates and enhances the flexibility of the final seal.
