Two-Component Polyurethane Adhesive is a premium, high-performance structural adhesive that cures through a chemical reaction between Part A (base) and Part B (hardener). It combines exceptional bonding strength with outstanding flexibility, making it ideal for applications where movement, vibration, or thermal expansion is expected.
It is especially recommended for stone bonding (granite, marble, quartz, artificial stone), construction joints, precast elements, and repair work. This adhesive creates tough, long-lasting bonds that resist water, weather, and chemicals while maintaining elasticity.
Key Advantages:
Superior flexibility and impact resistance
Excellent adhesion to multiple substrates
Waterproof and weatherproof for indoor & outdoor use
Outstanding gap-filling capability
Low shrinkage and low-VOC options available

Main Benefits
Strong Yet Flexible Bond: High peel and shear strength with excellent elasticity — perfect for stone, concrete, and dissimilar materials.
Weather & Moisture Resistant: Ideal for exterior stone cladding, landscaping, and wet environments.
Versatile Application: Bonds stone, metal, wood, plastics, ceramics, glass, and many other materials.
Easy to Use: Thixotropic (non-sag) formulas available for vertical and overhead bonding.
Durable Performance: Withstands temperature fluctuations, vibration, and long-term aging.

How to Use
Surface Preparation: Clean and dry all bonding surfaces. Remove dust, grease, and loose particles. Lightly abrade smooth surfaces for better adhesion.
Mixing: Mix Part A and Part B thoroughly in the correct ratio until the color is uniform.
Application: Apply the mixed adhesive to one or both surfaces using a trowel, spatula, or dispensing gun.
Assembly: Join the parts firmly and apply pressure. Use temporary supports or clamps if necessary.
Curing: Allow to cure undisturbed. Clean excess adhesive before it sets.
Tip: Always perform a small test on your specific stone type first.
