PVA 100-84 Application
It is a high-viscosity, fully hydrolyzed polyvinyl alcohol with high molecular weight, ultra-strong adhesion and steady mechanical properties. This grade is tailor-made for high-viscosity adhesive formulas as well as premium architectural and industrial coatings.
Used for high viscosity adhesive
It is a key functional raw material for producing high-strength, high-viscosity waterborne adhesives. Thanks to its ultra-high molecular weight, it delivers prominent thickening capacity, great initial tack and reliable ultimate bonding strength. It cures into tough, transparent and waterproof adhesive films that bond stably to wood, paper, textiles and diverse porous substrates. It is extensively adopted for composite adhesives, structural water-based adhesives and all kinds of high-viscosity industrial bonding formulas.
Used for high grade paint
Serving as a premium functional additive for construction and industrial coatings, it boasts outstanding thickening, leveling and film-forming capabilities. It greatly boosts coating uniformity and pigment suspension stability to avoid pigment sedimentation and liquid delamination. Once cured, it improves coating hardness, abrasion resistance, water resistance, and weather durability, remarkably enhancing surface smoothness and the overall performance of high-end coatings.
