Description

Tannin Formaldehyde CAS NO 9010-29-1 is a synthetic resin produced by the condensation reaction of tannin extracts with formaldehyde. This compound is valued for its ability to impart high durability, water resistance, and adhesive strength to various materials. It serves as a critical component for manufacturers in the woodworking, leather tanning, and foundry industries seeking robust and sustainable binding solutions.

Application

• Wood Adhesives & Panel Manufacturing: Used as a binder in the production of plywood, particleboard, and fiberboard, offering excellent moisture resistance.
• Leather Tanning Auxiliary: Acts as a retanning agent to improve leather's fullness, grain tightness, and dye uniformity.
• Foundry Sand Binders: Employed as a core binder in metal casting for its good thermal stability and breakdown properties.
• Water Treatment: Functions as a coagulant aid or flocculant in the treatment of industrial wastewater.
• Corrosion Inhibitor Formulations: Incorporated into coatings and treatments to provide a protective barrier on metal surfaces.
• Textile Processing: Used to improve the fastness of dyes and as a finishing agent for fabrics.
