Manta MF3 Alkoxy silane–terminated polyether polymer designed for moisture-curing elastic sealants and sealing coatings.

Product Description

Manta MF3 Alkoxy silane–terminated polyether polymer designed for moisture-curing elastic sealants and sealing coatings.
Sealants formulated with MF3 exhibit excellent adhesion across a wide variety of substrates. Unlike polyurethane or silicone systems, these formulations are solvent- and isocyanate-free, producing no bubbles or odor during curing.
The product is well suited for applications in the construction, transportation, and general industrial sectors.

Properties

  • Low Activity, low shrink.
  • Lower viscosity, could adding more powder
  • Good adhesion strength and tensile elasticity
  • Excellent aging and yellowing resistance
  • Excellent water resistance , resistance to chemical corrosion
  • Solvent free , odourless , eco-friendly
  • Could be blended with other Manta polymers

Applications

MF3 polymer is used as base polymer in elastic sealants, elastic structure sealants, encapsulate adhesives and coatings . The curing mode of the polymer is moisture curing, It can be made into a single component or two components system.

  • High hardness sewing sealant
  • Transportation industry elastic sealant
  • Low viscous encapsulate adhesive
  • Personal DIY sealant
  • Eco-friendly decoration sealant

 

Processing  

Manta MF3 polymer is readily soluble in common organic solvents such as ethanol, while remaining virtually insoluble in water. As a result, formulation components are typically oil-soluble materials.

The curing mechanism is based on moisture-initiated silane reactions: in the presence of a catalyst, terminal silane groups undergo hydrolysis to form silanols, which subsequently condense to create siloxane crosslinks, producing a three-dimensional network structure.

Although MF3 polymer contains highly reactive functional groups, it remains stable for a certain period under catalyst-free conditions. Moisture control is critical during storage and processing. To ensure formulation stability, the addition of a chemical moisture scavenger is required; vinyl trimethoxysilane is recommended.

MF3 polymer can be processed using conventional mixing equipment. For further technical assistance, please contact our technical support team.
