Das zeichnet Sikaflex PRO-3 Purform aus

The polyurethane-based chemistry of this sealant combines elasticity with structural strength, making it suitable for dynamic joints where materials expand and contract with temperature changes. Unlike rigid adhesives, the formula remains pliable over time, maintaining the seal integrity without cracking or shrinking.

Ideal für...

Professional tradespeople and DIY users working on building construction, renovation, and repair projects. The product is suited for sealing joints in facades, window frames, roofing elements, and general construction assemblies where a durable, flexible bond is required.
