Primer Layer

Brief Description

Wepox 120 (A+B) is a solvent-free primer for concrete. Wepox 120 (A+B) is tested to the “Technical Delivery Specifications / Technical Test Specifications for Catalyzed Resins for Primers, Sealants and Scratch Coats under Asphalt Surfacing on Concrete”, (TP-BEL-EP) and the additional H PMMA requirements and may be used for the production of waterproofing systems consisting of a welded polymer-bitumen sheet on a seal coat, primer or scratch coat based on epoxyde resin for civil engineering structures. Wepox 120 (A+B) is approved for application to young concrete (> 7 d). The application and usability on structures and components of the Federal Transport Network is verified in the \"Compilation of certified substances and substance systems according to TL-BEL-EP”, a list by the Federal Highway Research Institute (BASt).

Material

2-component, epoxy-based catalysed resin

Application

The product can be used for new surfacing or existing surfacing that needs to be fully or partially replaced and that is applied to concrete bridge deck slabs, with welded polymer bitumen sheeting as the waterproofing layer. Wepox 120 (A+B) is approved and tested (abP: P 12675/ 20-606, Kiwa Flörsheim) in accordance with TL/TP-BEL-EP as well as the compatibility tests in accordance with TL/TP-BEL-B, part 1 and can therefore be applied on bridge deck surfacing on concrete with a welded polymer-bitumen sheeting as waterproofing layer. Approved Welded polymer-bitumen sheeting: • BÖRNER OK 50 N – Welded polymer-bitumen sheet (test report P12477-2) • VEDAPONT BE – Welded polymer-bitumen sheet (test report P12477-1)
