UR 3370 Grey is a fast-curing one-component polyurethane adhesive sealant. This non-sag, multi-purpose adhesive forms a flexible, durable, and resistant elastomeric seam with good adhesion to most industry materials. Skin formation and curing time depend on humidity, temperature, and joint depth. UR 3370 Grey has high initial tack and excellent resistance to tear, vibration, and weathering. It is easy to apply and adheres without a primer to common substrates such as glass, aluminum, metal, wood, and concrete.

Features:

• Its non-sag, flexible, durable, and resistant elastomeric seam that exhibits strong adhesion to a variety of industry materials.
• The graded density construction is designed to prevent significant pressure drops during filtration, ensuring consistent and efficient flow rates throughout the cartridge's lifespan.
• The product exhibits a high initial tack and exceptional resistance to tearing, vibrations, and weathering..
• The duration it takes for the adhesive's surface to develop a skin when exposed to atmospheric moisture at 25 ± 2 °C and 50 ± 5% RH.
