About WestWood
WestWood Kunststofftechnik AG is the Swiss branch of WestWood Kunststofftechnik GmbH with its company headquarters in Petershagen (East Westphalia), and develops, produces and distributes waterproofing, coating and marking systems based on PMMA liquid plastics (polymethyl methacrylate). The product lines Wecryl (waterproofing and coating for balconies, terraces, flat roofs, multi-storey car parks and bridges) and WeTraffic (structured surfacings, roller coatings and roller-applied markings for traffic areas) cover the entire system range from primer through waterproofing, protective and wearing layers to repair mortars and accessories. Production is Made in Germany in Petershagen-Lahde with a capacity of 9,000 tonnes per year; the systems are solvent-free, free of PFOA/PFAS, cure in a short time and are in use in 16 countries worldwide. The Swiss branch in Rudolfstetten offers technical consulting, application technology, processing training as well as project-specific solutions for multi-storey car park construction, road construction, bridge construction, building construction and special applications.

Materials & Systems
PMMA (Polymethyl Methacrylate)
Base material of all Wecryl and WeTraffic systems: fast-curing, solvent-free 2K resins for waterproofing, coating and marking
Methyl Methacrylate (CAS 80-62-6)
Main component of the PMMA resins for rapid curing and high adhesion
Bisphenol A - Epoxy Resins (CAS 25068-38-6)
Component in Wecryl 176 primer for improved adhesion on absorbent substrates
Bauxite (aggregate)
Hard grain in WeTraffic 491/492/493/496 BX for maximum abrasion resistance and skid resistance (PSV 70–80)
Quartz Sand/Quartz Flour (CAS 14808-60-7)
Broadcasting aggregate and filler for grip and structure in coatings
Silicon Carbide (SiC)
Broadcast grit on stair treads for slip safety and improved thermal conductivity with underfloor heating
Concrete
Main substrate for multi-storey car parks, underground garages, roundabouts, balconies and bridges
Mastic Asphalt / Asphalt Concrete
Traffic-area substrate for WeTraffic structured surfacings and markings
Steel / Cr-Ni Steel
Substrate for metal primer systems and bonding, e.g. checker plate profiles on staircase structures
Polymer Bitumen Waterproofing Membranes / TPO-FPO Membranes
Substrates with specific bonding primers (Wecryl 125, Wethan 109)
