Product Description
Merbenit 2K10 is an elastic 2K-SMP adhesive with approx. 30 minutes of processing time — cures independently of air humidity, ideal for thick layers and moisture-proof substrates.
Silan-modified polymers (SMP) are modern high-performance adhesives — moisture-curing, solvent-free, isocyanate-free, and silicone-free, with a very broad adhesion spectrum on metals, painted and galvanized surfaces, engineering plastics, glass, ceramics, concrete, stone, and wood. Paint-compatible, corrosion-protective, shock- and vibration-resistant, low-odor. 2K10 is a specific variant of the Merbenit SMP series — the most important properties and applications are listed below.
Merbenit 2K10 is the long-pot-life 2K variant — crosslinked by chemical reaction, independent of humidity. Ideal for thick layers, moisture-proof substrates, and applications with long processing times. Shore A 45, 300% elongation at break.

Frequently asked questions about 2K10
Practical application and design questions — answered by SILITECH.
Merbenit 2K10: Elastic 2K-SMP adhesive with approx. 30 minutes working time — crosslinks independent of humidity, ideal for thick layers and moisture-proof substrates. Main applications: Thick adhesive layers, moisture-proof substrates, metal construction, apparatus and machinery construction.
1K-SMP adhesives crosslink through air humidity — with thick layers or moisture-impermeable substrates, crosslinking in the interior can be significantly delayed. 2K-SMP adhesives crosslink through a chemical reaction between Component A and B — independent of humidity, curing through in thick layers and on non-absorbent substrates. Choose 2K when: layer thickness > 5 mm, substrates without moisture permeability (glass, metal with dense coating), controlled rapid curing is desired, processing in a static mixer machine.
2K10 adheres to metals (aluminum, stainless steel, steel), powder-coated and painted surfaces, galvanized/anodized/chromated/zinc-coated substrates, many plastics, ceramics, stone, concrete, render, wood, and glass. Not suitable for: PP, PE, PTFE (Teflon), silicones, and bituminous substrates. For critical material combinations, we recommend a preliminary test or the use of a primer (V40 for smooth, V21 for absorbent substrates).
Store in 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. Process opened cartridges promptly — 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 about the optimal choice, we will be happy to advise you — contact SILITECH with your specific application (substrate pairing, desired hardness, processing workflow, certification requirement).
