Sarnacol®-2142 S
Single-component moisture-curing PU adhesive for felt-backed Sarnafil membranes
Product Overview
Sarnacol-2142 S is a single-component, moisture-curing polyurethane adhesive used to bond Sarnafil felt-backed single-ply roof waterproofing membranes to the roof substrate. It is applied by roller and adheres to a wide range of solid, clean, dry or slightly moist surfaces, including concrete, plywood, fibre cement, bituminous sheets, insulation boards and metal panels. It is intended specifically for Sarnafil G Felt-type and Sarnafil T Felt-type membranes, providing a durable, fully adhered roof build-up with a long track record. Supported by Factory Mutual certification, it suits roofing contractors and waterproofing applicators delivering adhered flat-roof systems. Space Arc Engineering, an authorized Sika distributor in India, supplies Sarnacol-2142 S for single-ply roofing and waterproofing projects.
