Merbenit SK212
1K-SMP disc adhesive with very high immediate adhesion.
1K-SMP windscreen adhesive with very high immediate adhesion — FMVSS 212 certified, drive-away time 60 minutes, Euro-NCAP frontal impact 64 km/h, GPS/assistance compatible
HS code:
3214.1000
Merbenit SK212 is a 1K-SMP windscreen adhesive with very high immediate adhesion — FMVSS 212 certified, drive-away time 60 minutes, Euro-NCAP frontal impact 64 km/h, GPS/assistance compatible.
Silane-modified polymers (SMPs) are modern, high-performance adhesives—moisture-curing, solvent-, isocyanate-, and silicone-free, with a very broad adhesion spectrum to metals, painted and galvanized surfaces, engineering plastics, glass, ceramics, concrete, stone, and wood. They are paintable, corrosion-resistant, shock- and vibration-resistant, and low-odor. SK212 is a specific variant of the Merbenit SMP series—its key properties and applications are described below.
Merbenit SK212 is the automotive-grade windshield adhesive – specifically for windshield replacement and general glass bonding in cabins and vehicles. FMVSS 212 certified with a 60-minute drive-away time, Euro NCAP frontal impact 64 km/h, and high electrical resistance for aluminum body panels with GPS and driver assistance systems.

Frequently asked questions about SK212
Practical application and design questions — answered by SILITECH.
Merbenit SK212: 1K-SMP windshield adhesive with very high initial tack — FMVSS 212 certified, 60-minute drive-away time, Euro NCAP frontal impact 64 km/h, GPS/assistance compatible. Main applications: Windshield replacement, cabin glazing, vehicle side windows.
SMP = Silane-modified polymer. This modern class of adhesives combines the advantages of silicone (elasticity, weather resistance, broad adhesion spectrum) and polyurethane (mechanical strength, paintability) — without their disadvantages (silicone: not paintable, corrosion on some metals; PU: isocyanates, often problematic indoors). SMP adhesives are solvent-, isocyanate-, and silicone-free, paintable, corrosion-resistant, and adhere to most substrates without a primer — except PE, PP, PTFE, and silicones.
SK212 adheres to metals (aluminum, stainless steel, steel), powder-coated and painted surfaces, galvanized/anodized/chromated/zinc-coated substrates, many plastics, ceramics, stone, concrete, crepi, wood, and glass. Not suitable for: PP, PE, PTFE (Teflon), silicones, and bitumen substrates. For critical material pairings, we recommend a preliminary test or application with a primer (V40 for smooth, V21 for absorbent substrates).
Store in the unopened original container in a dry, cool place — typically between +5 and +30 °C. Consult the Safety Data Sheet (SDS) before use. Observe the expiry date on the packaging. Use opened cartridges quickly — skin formation in the nozzle will block further application.
In the comparison table above, you will find related Merbenit products with different properties—different hardness, pot life, elongation at break, or special certifications (IMO, EN 45545-2, FMVSS 212, ISEGA, Minergie-ECO). If you are unsure which product is best for you, we would be happy to advise you—contact SILITECH with your specific application (substrate pairing, desired hardness, processing workflow, certification requirements).
