Merbenit TMS32

Merbenit · SKU 92-TMS32.KT.ML290.GS

Merbenit TMS32 is a highly elastic 1K-SMP adhesive/sealant (500% elongation at break) with a very broad adhesion spectrum on plastics — Minergie-ECO, ISEGA-approved, suitable for sanitary applications.

Silane-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. TMS32 is a specific variant of the Merbenit SMP series — the most important properties and applications are listed below.

500% elongation at break — highest tolerance

Merbenit TMS32 is characterized by an exceptionally high elongation at break of 500% with a soft-elastic consistency (Shore A 34) — tolerates large movements and expansions. Especially suitable for natural stone (no edge discoloration), wooden floors such as parquet, sanitary joints (mold-resistant), and window connection joints.

Processing

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.

Primer (if required)

On smooth substrates use Primer V40, on absorbent substrates Primer V21. On powder-coated surfaces and plastics, Primer V40 is recommended.

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).

Application

Apply as a uniform bead or spot bonding. Join within the open time — press the components together with sufficient pressure.

Smoothing + correcting

Within the working time (5–30 min depending on variant), smooth with a smoothing tool or correct the position.

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 TMS32

Practical application and design questions — answered by SILITECH.

What is TMS32 used for?

Merbenit TMS32: Highly elastic 1K-SMP adhesive/sealant (500% elongation at break) with a very broad adhesion spectrum on plastics — Minergie-ECO, ISEGA-approved, suitable for sanitary applications. Main applications: natural stone jointing, wooden floors / parquet, sanitary joints.

What is an SMP adhesive?

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.

Which substrates can be bonded?

TMS32 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).

How is TMS32 stored?

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.

What alternatives are available from the Merbenit series?

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).
