Do You Konw The Difference between Silicone Sealant And MS Sealant ?

01 Different components 

  Silicone rubber is composed of 107 silicone oil, silica and other components of silicone rubber, with fast curing, no foaming, can be firmly bonded to the surface of non-porous materials, moisture and heat resistance, excellent aging resistance, good storage stability; MS adhesive is a silane-terminated polyether containing polyurethane groups, non-toxic, tasteless, low VOC content, strong stability, strong compatibility, good uniformity and other advantages

02 Different properties

  Silicone glue is a kind of ointment form, contact with moisture in the air will be cured into a tough rubber solid material, its heat resistance is good, high and low temperature resistance is excellent, MS glue is a silane-based polyether crosslinked polymer, under the joint action of moisture and appropriate catalyst, molecular chain condensation reaction, release water and alcohol substances, The molecules are cured to crosslink into elastomers, but because of the low polyether bond energy, the C-O bond is easy to break, and the heat resistance is relatively poor.

03 Different viscosity

Silicone adhesive has strong adhesion, high tensile strength, and excellent properties such as weather resistance and shock resistance. MS adhesive adhesion is good, can absorb and compensate dynamic load, uniform transfer force.

04 Uses different

 silicone adhesive can be divided into sealant, weather resistant adhesive, structural adhesive and other different types, generally used for doors and Windows caulking seal and interior decoration engineering, insulating glass seal, etc., structural class silicone adhesive can be used in structural assembly, such as glass curtain wall, stone curtain wall, steel structure and other fields of bonding and sealing, a wide range of applications; MS adhesive to acrylic, ABS, plexiglass and other engineering plastics and concrete and other porous materials have a good bonding force, widely used in electronic adhesives, industrial adhesives, building external sealant and suitable for internal industrial assembly of various adhesives.
