MS Polymer Type STPE
Moderate-Modulus STP Polymer | Manta MS3030T
Manta MS3030T is a silyl-terminated polyether (STPE) on a polyoxypropylene backbone, used as a base polymer for elastic sealants, structural adhesives, encapsulants and coatings in construction, transportation and DIY markets. It cures with moisture without releasing CO2, giving bubble-free, low-odor joints, and is solvent-free and isocyanate-free.

- Light yellow, transparent liquid
Overview
Manta MS3030T is a silyl-terminated polyether based on a polyoxypropylene backbone with moisture-reactive silyl end groups. It provides a solvent-free and isocyanate-free base for elastic sealants and adhesives and is an alternative to conventional polyurethane and silicone systems.
The polymer cures at ambient temperature by reaction with moisture and can be formulated as a one-component (1K) or two-component (2K) system. Unlike polyurethane systems it releases no CO2 during curing, so formulations cure without bubbles and with low odor. The low glass transition temperature (Tg) of the polyether backbone helps maintain flexibility over a wide temperature range.
MS3030T has the same moderate activity and moderate modulus as Manta MS2030T and has the higher viscosity of the two: 10,000 – 15,000 mPa·s at 25 °C compared with 6,000 – 10,000 mPa·s at 25 °C.
Key Features
- Moderate activity and moderate modulus
- Good adhesion strength
- Room-temperature curing; tin-free catalysts can be used where required
- Good resistance to aging and yellowing
- Good resistance to water and chemical attack
- Good elastic recovery
- Good storage stability
- Solvent-free and low odor
- Can be blended with other Manta polymers

Applications
- Construction: can be formulated into low-modulus sealants for expansion joints and facades with good weathering resistance and movement capability
- Transportation: elastic sealants for rail vehicles, buses and specialty vehicles
- Consumer and DIY: easy-to-use sealants with bubble-free curing
- Interior decoration: solvent-free, low-odor and paintable decoration sealants
- Industrial assembly: binder for elastic adhesives and potting compounds in electronics and general manufacturing; electrical properties to be verified in the final formulation
Processing
Manta MS3030T is readily soluble in common organic solvents (e.g., ethanol) and practically insoluble in water; formulation components should therefore be oil-soluble. The terminal silane groups hydrolyze with moisture to silanols, which condense in the presence of a catalyst to form a siloxane (Si–O–Si) network.
Without catalyst the polymer is stable in air for a limited time, but moisture must be controlled during processing and storage. Dry all raw materials and add a moisture scavenger such as vinyltrimethoxysilane (VTMO) to ensure the shelf life of the formulated product.
Conventional mixing equipment can be used. Please contact Manta technical service for formulation support.
Cleaning
Uncured material can be removed with common organic solvents such as ethanol or dimethyl carbonate (DMC). Cured material can only be removed mechanically.

Frequently Asked Questions
How do I prevent premature gelation of Manta MS3030T during compounding and storage?
Moisture control is the key point, because the terminal silane groups hydrolyze with moisture. Dry all raw materials and add a moisture scavenger such as vinyltrimethoxysilane (Manta V31) to ensure the shelf life of the formulated product. Without catalyst the polymer is stable in air only for a limited time.
Does Manta MS3030T need a tin catalyst to cure?
No. Tin-free catalysts can be used where required. MS3030T cures at room temperature: the terminal silane groups hydrolyze with moisture to silanols, which condense in the presence of a catalyst to form a siloxane network.
Why do sealants based on MS3030T cure bubble-free compared with polyurethane systems?
Unlike polyurethane systems, MS3030T releases no CO2 during its moisture cure, so formulations cure without bubbles and with low odor. The cure builds a siloxane (Si-O-Si) network from hydrolyzed silanol groups.
How can uncured or cured MS3030T be cleaned from equipment?
Uncured material can be removed with common organic solvents such as ethanol or dimethyl carbonate (DMC). Cured material can only be removed mechanically.
What packaging and shelf life does MS3030T come with?
Packaging: 50 kg plastic drum with aluminum-foil liner bag; 200 kg drum with aluminum-foil liner bag; 1,000 kg IBC (tote); other pack sizes available on request. Store in the tightly closed original container in a cool, dry place, protected from moisture and direct sunlight. Shelf life: 12 months from the date of production when stored as recommended. The product is classified as non-hazardous. Refer to the current Safety Data Sheet (SDS) for safety, handling and transport information.
