e-lastic 250 Liquid-applied polyurethane waterproofing membrane
e-lastic 250 is a premium, liquid-applied, semi-thixotropic, highly permanent elastic, cold applied and cold curing, one component polyurethane membrane used for long lasting waterproofing. e-lastic 250 is based on pure elastomeric hydrophobic polyurethane resins, which result in excellent mechanical, chemical, thermal, UV and natural element resistance properties. Cures by reaction with ground and air moisture.
1.4 to 2.5 kg/m² applied in two or three layers. This coverage is based on application by roller onto a smooth surface in optimum conditions. Factors like surface porosity, temperature and application method can alter consumption.
e-lastic 250 is supplied in white and light grey. Other colors can be supplied by special order, subject to minimum quantity requirements.
e-lastic 250 was tested by the German state testing institute for construction materials MPA-Braunschweig according the European Union Directive for liquid-applied roof waterproofing kits ETAG 005 and was found conforming.
e-lastic 250 was certified by the German state Institute for construction techniques DIBt–Berlin with the European Technical Approval (ETA) and with the CE-mark and certification according to the EOTA (European Organization of Technical Approval).
e-lastic 250 was also tested and approved by various laboratories in different countries around the world.
