Primer Layer

Brief Description

Wecryl 123 K is fast-curing, pre-filled and solvent-free scratch coat, tested in conjunction with Wecryl 123 on the basis of 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. Wecryl 123 K may be used for the production of waterproofing systems consisting of a welded polymer-bitumen sheet on a PMMA-based seal coat for civil engineering structures.

Material

2-component, fast-curing, catalysed PMMA-based resin (PMMA = polymethyl methacrylate)

Application

he 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. Wecryl 123 K is approved and tested (test report no. 16/11057/01, Kiwa Flörsheim) in accordance with TL/TP-BEL-EP and H PMMA as well as the compatibility tests in accordance with TL/TP-BEL-B, part 1 and can therefore be applied as bridge deck surfacing on concrete with a welded polymerbitumen sheeting as waterproofing layer. Approved welded polymer-bitumen sheeting: • BÖRNER OK 50 N – Welded polymer-bitumen sheet • VEDAPONT BE – Welded polymer-bitumen sheet

Properties and advantages

• Easy to apply
• Fast-curing
• Hydrolysis- and alkali-resistant
• Heat-resistant (welded sheeting, mastic asphalt)
• Solvent-free
• Can be used at temperatures as low as 0 °C
