Sikaflex PRO-3 Purform is a 1-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.
Characteristics & Advantages:
High movement capability: +/-25% (ISO11600) & ±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)
