“The challenge lies in protecting and stabilizing the polymer in an aqueous environment”
Advancing waterborne 2K PU technology in wood coatings
Keith Rawlins
Technical Sales Manager at Sun Polymers International
Keith Rawlins, Technical Sales Manager at Sun Polymers International, discusses the complexities of balancing VOC reduction with performance in waterborne 2K PU wood coatings. Learn how innovative resin architectures are pushing boundaries in drying speed, film hardness, and chemical resistance while meeting sustainability goals.
Your hydroxyl-terminated polyester-acrylic dispersion introduces a novel resin architecture. How does this structure help overcome traditional limitations in drying speed and film hardness?
The key is utilizing a high-molecular-weight polyester shell that acts as a functional part of the polymer versus traditional emulsifiers that hinder coating integrity. This polyester allows for superior hardness and improves dry time.
Keith Rawlins will present “Hydroxyl-Terminated Polyester Acrylic Dispersions for WB 2K PU Wood Coating” on Wednesday, May 6, at 4:30 p.m. in Session 11: Polyurethanes.
Mechanical performance and chemical resistance are often seen as trade-offs in waterborne systems. What performance gains does the H-PAD system deliver compared to conventional waterborne PU binders?
The performance benefits are significantly improved in the areas of dry time, chemical resistance, water resistance, flexibility, and pot life, which far surpasses what has been achieved previously.
