Description

Toluenesulfonamide Formaldehyde Resin is a synthetic, thermoplastic resin produced by the condensation reaction of toluenesulfonamide with formaldehyde. This compound is valued for its excellent compatibility with a wide range of polymers and its ability to act as a permanent plasticizer and processing aid. It is primarily sought after by manufacturers in the coatings, adhesives, and plastics industries to enhance flexibility, adhesion, and flow properties in their formulations. The product is supplied under the CAS registry number 25035-71-6.

Application

• As a permanent plasticizer and resin modifier in nitrocellulose lacquers and coatings to improve flexibility and adhesion.
• Key component in adhesive formulations, particularly for laminates and specialty tapes, to enhance tack and bond strength.
• Processing aid and flow modifier in thermoplastic and thermosetting resin systems, including phenolics and polyamides.
• Used in printing inks to improve gloss, rub resistance, and pigment wetting.
• As a film-forming agent and binder in specialty industrial and wood coatings.
• Modifier for synthetic fibers and textiles to impart specific functional properties.
