Sarnacol®-2170
Solvent-based nitrile-rubber contact adhesive for bonding Sarnafil single-ply roofing membranes
Product Overview
Sarnacol®-2170 is a one-part, solvent-based contact adhesive built on a nitrile-rubber binder, formulated to bond Sika’s Sarnafil G-type and G Felt-type PVC roofing membranes to a wide range of roof decks and detailing surfaces. It works on concrete, brick, plaster, OSB, plywood, fibre-cement and mineral-fibre boards, galvanised steel, soft PVC and PUR/PIR insulation, making it the go-to adhesive for adhered flat-roof build-ups and perimeter or upstand details. Applied by brush or roller using contact or wet-bonding techniques, it delivers a fast, durable grab once the membrane is set in place. Roofing contractors, waterproofing applicators and façade-roof specialists rely on it for adhered Sarnafil systems. Space Arc Engineering, an authorized Sika distributor in India, supplies Sarnacol®-2170 for project requirements nationwide.
