UF Hardener is a high-performance Urea Formaldehyde hardening agent designed to improve bonding strength, curing performance, durability, and stability in wood adhesives, particle boards, laminates, and moulding compounds.
Latent hardener for urea formaldehyde impregnation resins with long pot-life and high curing activity. UF Hardener (Urea Formaldehyde Hardener) is widely used in the wood and furniture industry as a catalyst and curing agent that enhances the strength and durability of UF resins. It ensures fast curing, excellent bonding, smooth finishing, and superior water resistance when used in particle board, plywood, laminates, MDF, and moulding applications.
