Key Features and Benefits

Applies to Wet Surfaces
Designed for real-world conditions—bonds and seals even on damp or wet substrates.

Clean White Finish
Ideal where a neat, opaque white joint or seal is required.

Strong and Flexible Bond
Permanently elastic once cured, with a high tensile strength of 220 N/cm² and elongation at break exceeding 350%.

Fungus and Bacteria Resistant
Perfect for sanitary areas such as kitchens and bathrooms, helping maintain long-term hygiene.

Safe for Sensitive Surfaces
Non-staining on natural stone and suitable for use on mirrors and delicate materials.

Eco- and User-Friendly
Solvent- and isocyanate-free with minimal odour—safe for indoor applications.

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

Excellent Material Compatibility
Adheres to most construction materials including tiles, cement, concrete, wood, aluminium, and more (not suitable for PP, PE, PTFE, or bitumen).

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