Product Description

 Modified Silane Polyether Sealant, also known as silicone modified polyether sealant and terminal silane polyether sealant, is a high-performance polymer environmental sealant. Because of its advantages of both silicone sealant and polyurethane sealant, it exhibits excellent weatherability &durability, high resistance to deformation, good adhesion, fineness, environmental friendliness, low stain , low viscosity and excellent workability, etc.,. It has been got more and more attention to the domestic construction industry, and in the industrial areas such as automobile manufacturing, rail transportation, container manufacturing, equipment manufacturing, electrical and electronic fields are also getting more and more promotion  and application.

SMP333 Industrial Modified Silane  MS Polymer Sealant is a high performance, single component,moisture curing,modified silane (MS) polymer based sealant. It will can bond damp surfaces and may even be used underwater. It havs very low odour,cures to form a hard elastic rubber, the rubber can be paintable,with almost no shrinkage. High position tack and vibration absorption; Broad adhesion range without use of primers; Excellent UV and Weathering resistance.

1. Universality to substrates bonding

 Due to the low surface energy and high permeability of the base polymer (terminal silyl polyether), it has a good wetting ability for most inorganic, metal and plastic substrates, resulting in good adhesion to the substrate.

2. Excellent Weatherability & durability

3.Environmental Friendliness

No additives of organic solvents;  very Low volatile organic compounds.

4. Paintable

Main Application
Applicable to  vehicles bonding , RV side panels and roof leather bonding
Applicable to bonding car body, train carriage, container and metal construction 
Applicable to bonding in electronic, plastic, air conditioner and ventilation industry

Paint work can be done after the sealant surface dried and it won't affect  sealant curing.
Dust, oil,condensation and frost on the surface of substrates must be cleaned up before work.
