Two-component, epoxy-polyurethane sealant with high chemical and mechanical strength WHERE TO USE • ealing joints in vertical concrete structures, both S interior and exterior. • brasion resistant sealing of joints in industrial floors A subject to heavy traffic, both interior and exterior. • ealing joints in rubber and PVC floors. S Some application examples • ealing flexible joints in concrete walls. More in S general, for all vertical structures, both interior and exterior, where a thixotropic product with high resistance to chemical agents, waterproof and vapour permeability is required. • ealing joints in ceramic tile floors in areas subject S to heavy traffic such as supermarkets, industrial buildings with fork lift truck traffic, sidewalks, pedestrian crossings, arcades, squares, etc. • ealing movement joints in concrete floors in car S parks and industrial buildings subject to vehicle traffic or where a high resistance to chemicals is required. • ealing rubber and PVC flooring by filling the joints S between each single tile or the sheets. • lastic fillet seals for machine beds. E • lastic fillet seals for pipe-work, drains, man-hole E covers, etc. TECHNICAL CHARACTERISTICS Mapeflex PU30 is a two-component thixotropic sealant consisting of devoid isocyanate free polyurethane polymer (component A) and a special hardener (component B). Mixing the two components produces a uniformly coloured thixotropic paste, easily workable with a flat trowel. Mapeflex PU30 can be used on both vertical and horizontal surfaces. After hardening by chemical reaction alone, which takes place in approximately 24 hours without shrinkage, Mapeflex PU30 becomes elastic, resistant to water and heat, with high mechanical strength and abrasion-resistant properties, and a good adhesion to almost all materials that are commonly used in building. Mapeflex PU30 cannot undergo work elongation above 10%. It is therefore necessary that the concrete has completed the shrinkage phase before sealing the joints (whether the joints are expansion or distribution joints). The resistance of Mapeflex PU30 to chemicals is good; however, due to the variety of products and working conditions under which it can be used, it is advisable to carry out preliminary tests in cases of doubt. The temperature resistance of Mapeflex PU30 is between -30°C and +80°C. Mapeflex PU30 complies with Euronorm EN 15651-1 (“Sealants for external and internal façades”) with performance rating F-EXT-INT. RECOMMENDATIONS • Do not use on substrates that are subject to rising

completely and has not completed the shrinkage phase. It is not advisable to seal during the summer season; joints are at their maximum expansion. It is preferable to seal during the autumn. • Before sealing make sure the expansion of the joints do not exceed 10% of the initial width. If otherwise, prefer sealants that have higher elongation properties or increase the width of the joint (refer to our Technical Services Department). • Do not use on bituminous surfaces where the bleeding of oils may take place. • The product may change colour if exposed to UV rays without losing any of its...
