Do you really know ms polymer sealant?

Sealant refers to the sealing material which is deformed according to the shape of the sealing surface, not easy to flow and has certain cohesivity. Mainly used to fill the configuration gap, so as to play a sealing role of the adhesive. It has anti - leakage, waterproof, anti - vibration and sound insulation, heat insulation and other functions. Sealant from the application level classification, mainly including building sealant and structural sealant two categories. Many of their performance requirements are very similar, but the structural adhesive pays more attention to the strength of the adhesive, elongation and other mechanical properties, building sealant is more emphasis on atmospheric change resistance, ultraviolet resistance, aging resistance and other properties, the two are different, can not be mixed instead, in the selection of sealant, to choose the use of scenarios.

1.What is modified silane sealant?

MS modified silane sealant is a kind of high performance sealant based on silane terminated polyether (MS POLYMER). The alkoxy group of the silane modified by MS contacts water vapor and forms silico-hydroxyl Si-OH under the condition of catalyst. The silico-hydroxyl group and silico-hydroxyl group continue to condense under the condition of catalyst to form Si-O-Si structure, and finally form a network cross-linked structure. At the same time, non-toxic alcohol-OH substances are released.

2.The features of ms polymer sealant

1)Weatherproof:Due to the structure containing silicone and polyether structure, MS sealant has very good weather resistance while maintaining high elasticity.

2)Adhesiveness:MS sealant can be bonded to most substrates without bottom coating. Such as PVC, EPDM, glass, wood, stone and so on.

• 3)No pollution:In the bonding of stone and ceramic tile, MS sealant without penetration pollution.
  

• 4)Fast curing:MS sealant can cure quickly at low temperatures.
  

5)Easy to use:MS sealant can be constructed over a wide range of temperatures, even at low temperatures maintain good extrudability.

6)NCO free:MS sealant does not contain cyanate group, harmless to the environment and workers.

7)Solvent free:MS sealant production process without adding solvent, friendly to the environment, even can reach zero VOC emissions, so very suitable for home decoration use.

3.How to use ms polymer sealant?

The bonded surface must be clean before bonding, keep dry, no putty.Will ooze oil substrate is not suitable for direct coating sealant.Rust or corroded metal surface (such as aluminum oxidation, copper, iron oxidation rusty surface), in order to ensure the bonding effect, before coating the need to float on the surface of the rust off.

Paint can be sprayed only after the surface is cured. The drying temperature of the paint should not exceed 90℃, and it can withstand 150℃ (within 20 minutes) for a short time. The best gluing temperature is +15~+40℃. When the ambient temperature is low, the extrusion resistance increases. The glue can be placed in a warm environment for insulation.

MS sealant can also be called modified silane sealant, is a single component of improved silane sealant, due to no formaldehyde, no isocyanate, has no solvent, non-toxic tasteless and other characteristics, friendly to the environment and human body, adapt to the majority of the building substrate has good construction, bonding, weather resistance. Curable at room temperature. It is widely used in architectural decoration.
