Two Component Polyurethane Adhesive Sealant for Corner Angle Frame Assembly
PU-2838 Two Component Polyurethane Adhesive Sealant for Corner Angle Frame Assembly for Windows and Doors Aluminum Panel.
PU2838 is a solvent-free, environmentally friendly, Fast curing, two-component polyurethane structural adhesive with excellent adhesion and aging resistance.
Two-component (2K) polyurethane corner adhesives are specialized structural bonding agents consisting of a resin and a hardener. Designed to chemically cure without needing ambient moisture, they deliver high-strength, non-shrink, and weather-resistant joints. They are primarily used for assembling aluminum windows, doors, facades, and conservatories
Why Use 2K Polyurethane for Corners?
Closed-Joint Curing: Because they cure via chemical reaction, they are perfect for tight, enclosed spaces where standard one-component moisture-cure glues cannot dry properly.
High-Strength & Elasticity: They provide excellent structural strength while retaining enough flexibility to accommodate the thermal expansion and contraction of metal frames.
Gap-Filling: They possess excellent gap-filling properties, ensuring a solid bond even if joints aren't perfectly flush.
Durability: Once hardened, the bond is highly resistant to water, extreme temperatures, weathering, and aging
