Pedestrian and traffic areas.

Description

Sikaflex® PRO-3 Purform® is a one-part, moisture curing, elastic polyurethane sealant. It seals many kinds of joint configurations in floors and civil engineering structures.

The elasticity is maintained over a wide temperature range and high mechanical and chemical resistance provides good durability.

Features and benefits:

High movement capability: +/-25% (ISO11600) and ±50% (ASTM C920).
Fast development of mechanical properties.
High mechanical and chemical resistance.
High resistance to weathering.
Good durability.
Non-staining to a wide range of substrates.
Very low monomer content: no user safety training needed (REACH restriction 2023, Annex 17 entry 74).
Bubble-free curing.
Good adhesion to most construction materials.
