Key Features and Benefits

Applies to Wet Surfaces
Engineered for real-world conditions—bonds and seals even when surfaces are damp or wet.

Crystal Clear Finish
Invisible results for transparent applications or high-end finishes where appearance matters.

Strong and Flexible Bond
Once cured, remains permanently elastic with a high tensile strength of 220 N/cm² and elongation at break over 350%.

Fungus and Bacteria Resistant
Ideal for kitchens, bathrooms, and sanitary installations—keeps surfaces hygienic over time.

Safe for Sensitive Surfaces
Non-staining on natural stone and safe for use on mirrors, making it perfect for decorative or delicate installations.

Eco- and User-Friendly
Solvent- and isocyanate-free with minimal odour—safe for indoor use without harsh chemical exposure.

UV and Thermal Stability
Withstands harsh environments with thermal resistance from -30°C to +95°C (peak: 155°C) and good UV tolerance.

Excellent Material Compatibility
Adheres well to most construction materials including tiles, cement, concrete, wood, aluminium, and more (excluding PP, PE, PTFE, and bitumen).

Paintable
Can be overpainted with most solvent- and water-based paints once cured.
