Merbenit RV30 is a flame-retardant 1K-SMP sealant for railway vehicle construction — EN 45545-2 Hazard Level HL1 + HL2, R22+R23, without halogenated flame retardants.
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. RV30 is a specific variant of the Merbenit SMP series—its key properties and applications are described below.
Merbenit RV30 meets Hazard Levels HL1 and HL2 according to EN 45545-2 (requirement sets R22+R23) — tested for components EX12 (external seals) and IN16 (internal seals) in railway vehicles. Free of halogenated flame retardants, soft-elastic (Shore A 26).

Frequently asked questions about RV30
Practical application and design questions — answered by SILITECH.
Merbenit RV30: Flame-retardant 1K-SMP sealant for railway vehicle construction — EN 45545-2 Hazard Level HL1 + HL2, R22+R23, without halogenated flame retardants. Main applications: Railway vehicle external seals, railway vehicle internal seals, railway windows and doors.
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.
RV30 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).
