Polyurethane sealant with a low modulus of elasticity.
Ready-to-use one-component thixotropic product for flexible expansion joints and fillet joints in pre-fabricated buildings, conventional and ventilated façades and cracks with movement in service of up to 25% of the width of the joint. Compatible with all absorbent mineral substrates, metal surfaces, painted surfaces, wood, stone, brickwork and glass. Primer is not usually required. In spite of the high thixotropic nature of Mapeflex PU40 which allows it to be applied even in wide joints without running, the creamy consistency of the product makes the product easy to extract and smooth over. Once completely polymerised, Mapeflex PU40 may be painted over with paint normally used in the building industry. Certification: ISO 11600 F 25 LM and GEV EMICODE EC1 R. Please refer to the Technical Data Sheet before use.
