Waterproofing material mainly composed of hydrophilic polyurethane resin! It reacts directly with water and gels.
"Sunstopper F" is a polyurethane-based grout material that reacts immediately upon contact with water, forming a resilient and tough polymer gel that exhibits excellent water-stopping and waterproofing properties. Due to its low viscosity, it penetrates even small cracks and demonstrates a water-stopping effect through foaming pressure. It gels even in flowing water, becoming a robust rubber elastomer, and maintains a chemically stable water-stopping effect. 【Features】 ■ Blends with water in any ratio ■ Excellent safety and durability ■ Penetrates small cracks ■ Maintains a chemically stable water-stopping effect ■ Available in an easy-to-use cartridge type, etc. *For more details, please download the PDF or feel free to contact us.
