Keterangan Produk

TEROSON MS 930 is a gun-grade, one-component sealant based on silane-modified polymer (SMP). It cures by reaction with ambient moisture to form a soft, elastic seal with good movement capability and durable adhesion. The product is supplied as a thixotropic paste and is available in white, grey and black.

The sealant is free of solvents, isocyanates, silicones and PVC, offers excellent UV and weathering resistance, and is suitable for both interior and exterior joints on a wide variety of substrates.

Ciri-ciri Utama & Manfaat

  • Thixotropic, gun-grade paste – no sag in vertical joints (DIN profile 15 mm)

  • Forms a soft elastic seal with high elongation (≈ 250% at break, ISO 37)

  • Excellent UV and weathering resistance for indoor and outdoor use

  • Broad-spectrum, primerless adhesion to many metals, glass, ceramics and various coated surfaces (trials recommended)

  • Free of solvents, isocyanates, silicones and PVC; characteristic, low-odour formulation

  • Service temperature range from -50 °C to +80 °C, with short-term exposure up to 120 °C

  • Skin formation time approx. 10–40 minutes (23 °C / 50% RH)

  • Typical cure rate approx. 4 mm / 24 h (23 °C / 50% RH)

Aplikasi Tipikal

According to Henkel’s technical data, TEROSON MS 930 is designed for elastic seam and joint sealing in demanding transportation and industrial environments, including:

  • Vehicle body manufacture (passenger vehicles, commercial vehicles)

  • Railway carriages and containers

  • Ship and boat building

  • Metal fabrication and construction

  • Electrical, plastics, air-conditioning and ventilation industries

  • Conventional vehicle window glazing between rubber profiles and glass (good adhesion to most rubber qualities, including many EPDM-based profiles)

  • Bonding of floor coverings in bus manufacturing

It is particularly useful where long-term flexibility, UV resistance, and paintability (with suitable paints) are required.

Surface Preparation & Application

The following application guidance is based on Henkel’s technical data sheet:

  1. Penyediaan permukaan

    • Substrates must be clean, dry and free from oil, grease and dust.

    • Depending on the substrate, mechanical abrasion (roughening) and/or a suitable primer or adhesion promoter may be required to achieve optimum adhesion.

    • For plastics, release agents used in molding processes must be thoroughly removed before sealing or bonding.

    • Due to the variety of paints and powder coatings, preliminary tests are necessary to confirm compatibility and adhesion.

  2. Substrates with limitations

    • When bonding or sealing PMMA (e.g. Plexiglas®) and polycarbonate (e.g. Makrolon®, Lexan®) under stress, stress-cracking may occur; application trials are mandatory.

    • No adhesion to polyethylene, polypropylene or PTFE is obtained; these substrates are not recommended.

  3. Application equipment

    • Standard 310 ml cartridges can be applied with TEROSON hand or air pressure guns.

    • Foil packs (e.g. 310 ml and 570 ml) are applied with corresponding FK hand or air pressure pistols.

    • For bulk supply (hobbocks / drums), use high-pressure pumps with follower plates according to Henkel’s application guidelines.

  4. Processing conditions

    • Recommended joint application temperature: 5–40 °C.

    • Low material temperature increases viscosity and lowers extrusion rate; pre-warm the cartridges to room temperature for easier application.

  5. Pembersihan

    • Uncured material can be removed from tools and equipment using Henkel Cleaner + Diluent A, D or FL (or Teroson SB 450, depending on region).

Keselamatan & Pengendalian

Safety-related information below is summarised from Henkel’s Safety Data Sheet for TEROSON MS 930 BK. Always read the full SDS before use.

  • Avoid contact with skin and eyes; wear suitable protective gloves, eye protection and protective clothing.

  • Ensure good ventilation or extraction at the workplace.

  • Do not eat, drink or smoke while working; wash hands before breaks and after finishing work.

  • In case of accidental release, prevent product from entering drains, surface water or ground water; remove mechanically and dispose of according to local regulations.

  • For fire situations, all common extinguishing agents may be used; toxic gases may be released in case of fire.
