Merbenit ·

Merbenit HT50 is a 1K-SMP adhesive with high initial tack and rapidly increasing strength — combining easy processing with rapid strength build-up, ISEGA-approved for food contact applications.

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. HT50 is a specific variant of the Merbenit SMP series—its key properties and applications are described below.

High immediate adhesion — ready for immediate transport

Merbenit HT50 combines easy processing with high initial adhesion and rapidly increasing strength. Bonded parts can be transported after a short time, and fixings can be removed quickly. ISEGA-approved for food contact areas, with eco-bau ECO-BKP 1st priority, EMICODE EC1Plus and Eurofins IAC Gold.

Processing

1
Clean substrate
Bonding surfaces must be clean, grease-free, and dry — degrease with cleaning alcohol, isopropanol, or acetone. Bonding to PP, PE, PTFE, and silicone is not possible; bituminous substrates are also unsuitable.
2
Primer (if required)
On smooth substrates use Primer V40, on absorbent substrates Primer V21. On powder-coated surfaces and plastics, Primer V40 is recommended.
3
Open cartridge / pouch
Cut the cartridge nozzle to the desired bead cross-section and insert into a standard cartridge gun (290 / 310 / 400 / 600 ml).
4
Application
Apply as a uniform bead or spot bonding. Join within the open time — press the components together with sufficient pressure.
5
Smoothing + correcting
Within the working time (5–30 min depending on variant), smooth with a smoothing tool or correct the position.
6
Curing
Curing through air humidity — through-cure 2–3 mm in 24 h, fully crosslinked after 48 h. Higher air humidity accelerates crosslinking.

Frequently asked questions about HT50

Practical application and design questions — answered by SILITECH.

Merbenit HT50: 1K SMP adhesive with high initial tack and rapid strength development — combines easy processing with fast strength build-up, ISEGA-approved for food contact applications. Main applications: Immediate tack bonding, elevator construction, passenger bridges.

SMP = Silane-modified polymer. This modern adhesive class combines the advantages of silicone (elasticity, weather resistance, broad adhesion spectrum) and polyurethane (mechanical strength, paint compatibility) — without their disadvantages (silicone: not paintable, corrosion on some metals; PU: isocyanates, often problematic indoors). SMP adhesives are solvent-free, isocyanate-free, and silicone-free, paint-compatible, corrosion-protective, and adhere without primer to most substrates — except PE, PP, PTFE, and silicones.

HT50 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 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).
