Product Description

Manta MS4000H is a low-viscosity silyl-terminated polyether (STPE) — 15,000–30,000 mPa·s at 25°C — with methyldimethoxysilane end groups, medium modulus and low-to-medium activity. Its 30-minute surface-dry time and easy processing make it a backbone resin for industrial, transportation, construction and product-assembly adhesives and sealants.

Manta MS4000H is a Silyl-Terminated Polyether (STPE) engineered as the high-performance backbone for moisture-cured sealants, adhesives, and coatings. Trusted across diverse industrial sectors, Manta MS4000H delivers an optimized balance of long-term durability, high reactivity, and superior storage stability. This exceptional performance profile is achieved by fusing a robust polyether backbone with precision-engineered methyldimethoxysilane functional groups.

Properties

◼ Enhanced Hardness & Structural Rigidity: Ideal for high-modulus sealants and structural adhesives requiring high Shore A hardness.

Frequently Asked Questions

What does MS4000H's low viscosity mean for processing?

At 15,000–30,000 mPa·s it is the easiest-flowing grade in the Manta STPE range: simpler mixing and pumping, better filler wetting and more formulation headroom before the compound becomes too stiff to process.

What cured properties can I expect from MS4000H?

Typical cured values are tensile strength ≥0.4 MPa, elongation at break ≥100%, Shore A hardness ≥20, with a surface drying time around 30 minutes and pH 6.0–9.0. See the TDS for the full inspection standard.

Is MS4000H hazardous to ship?

No — it is a non-hazardous substance, virtually insoluble in water, with flash point above 100°C, and ships as standard cargo with a 12-month shelf life.

How is MS4000H packed?

50 kg foil-lined plastic drums, 200 kg foil-lined drums and 1,000 kg IBC totes, with customized packing available. Store sealed in a cool, dry place away from direct sunlight.
