ONE-component Polyurethane Adhesive is a moisture-curing structural adhesive formulated to form permanent bonds without the need for mixing, making it ideal for field applications and high-speed production environments. This adhesive operates through a moisture-initiated curing mechanism, where isocyanate groups in the prepolymer react with water (from air or substrate moisture) to form urea linkages, gradually building strength over time. Its single-package design eliminates mixing errors and reduces waste, ensuring consistent performance across applications. Cured adhesives exhibit tensile strength ≥8 MPa and elongation at break ≥400%, with a service temperature range from -40°C to 90°C that accommodates extreme environmental conditions. It forms elastic bonds that absorb vibration and movement, making it suitable for dynamic applications where rigid adhesives might fail .
Universal Substrate Compatibility
This adhesive bonds effectively to diverse substrates without primers, including mild steel, aluminum, glass, concrete, PVC, ABS, and treated wood. It achieves peel strength ≥4 N/cm on polycarbonate and ≥6 N/cm on anodized aluminum, outperforming many one-component adhesives in multi-material bonding scenarios. Its ability to wet low-energy surfaces reduces surface preparation requirements, simplifying application in field settings where extensive pretreatment is impractical .
Weather and Chemical Resistance
Cured adhesives resist UV degradation (ASTM G154) for ≥5 years of outdoor exposure, maintaining flexibility and bond strength without cracking or embrittlement. They withstand temperature cycling from -30°C to 80°C without delamination, making them suitable for climate-controlled and extreme environment applications. Chemically resistant to automotive fluids (engine oil, brake fluid), household cleaners, and saltwater, they maintain performance in harsh operating conditions .
Efficient Processing
Applied via standard caulking guns, cartridge dispensers, or automated application systems, this adhesive offers user-friendly processing with no mixing required. It develops a tack-free skin within 60–90 minutes for early handling, while achieving full cure in 24–72 hours at 23°C/50% RH. Its high green strength (≥0.5 MPa) enables vertical bonding without sagging, supporting applications like window installation and vertical panel assembly .
Sustainable Formulation
Select grades contain ≥30% bio-based content derived from renewable resources, aligning with sustainable manufacturing initiatives. Solvent-free and free from hazardous ingredients, they emit ≤5 ppm VOCs, meeting EU Ecolabel and LEED v4.1 criteria for green building materials. Their low environmental impact reduces regulatory compliance burdens in eco-sensitive applications .
Building and Construction
Window and Door Installation: Seals aluminum or PVC frames to insulated glass units (IGUs) and masonry substrates, providing air leakage rates ≤0.1 L/m·s and water resistance ≥1,000 Pa—performance metrics that contribute to energy-efficient building envelopes .
Roofing Membrane Bonding: Attaches EPDM or TPO roofing membranes to metal decks and insulation boards, forming wind-resistant bonds that withstand uplift pressures ≥2 kPa in high-wind zones .
Consumer Goods Manufacturing
Appliance Assembly: Bonds plastic trim, rubber gaskets, and metal components in refrigerators, dishwashers, and washing machines, ensuring hermetic seals (ASTM E96) and vibration damping during operation .
Footwear Production: Attaches rubber or PU soles to leather or textile uppers in athletic and work footwear, withstanding flex fatigue ≥10⁵ cycles without bond failure—critical for durability in high-use footwear .
Container: Store in airtight aluminum foil pouches or sealed cartridges to prevent moisture ingress, which triggers premature curing.
Conditions: Maintain storage temperatures between 5–25°C with relative humidity ≤50% to preserve shelf life (12–18 months from production date).
Handling: Avoid exposure to high humidity (>60% RH) during application; use dehumidified air in enclosed spaces to control cure rate.
