         Removal of hydroxylamine type bicomponent RTV silicone rubber has excellent resistance to high and low temperature resistance, at -50~150 ℃for long-term use; superior weatherability; good water resistance; on the glass, aluminum, excellent adhesion. Easy to use, quick construction, adhesive curing time is short. Therefore, widely used in building and decorative glass plate between the elastic connection and glass curtain wall, stone and metal curtain wall building structure elastic adhesive assembly. Silicone sealant in these buildings has become an important engineering material. Building on the use of silicone sealant mainly Condensation Type RTV silicone sealant ( RTV ). This type of sealant in the vulcanization process Mets discharge a small amount of low molecular substances.


         According to the release of low molecular substances, condensation type RTV silicone sealant can be divided into: acid type, deoximino type, dealcoholizing, ketonic type, de-amide type, and hydroxylamine. Removal of acetic acid type silicone sealant is the first introduction, development and production of silicone sealant, but because of its irritating smell, on the metal material corrosion reasons and its application was limited; dealcoholizing, deoximino type silicone sealant sealant is neutral, on the outside of the metal material of copper corrosion, is the development of the soon, the dosage is the biggest, the most widely used breeds; ketonic type silicone sealant surface dry time is very short, no corrosion, no pollution, high cost, is mainly used for electronic and electric industry; de-amide type silicone sealant can be made into a low modulus products, mainly used for sealing of joints in concrete.

 

Removal of hydroxylamine type bicomponent RTV silicone sealant can use time adjusting method.

1 added starch extend the use time; choice of potato starch, rice etc.. With the amount of 100 copies of 0.5~10 based polymer.

2 add a ring of two methyl silane or degree of polymerization of linear poly two methyl siloxane extending use time; can choose eight methyl four methyl two six ring silicone or silicone, 50 calcium carbonate, in three stick machine mixing, with base material.

3 add the specific structure of the organosilicon compound extending use time; the specific structure of the organosilicon compound, refers to the following results: the siloxane with amount of 100 copies of 1~10 based polymer. This method does not affect the adhesive sealant.
