RTV-Ⅱ
Silicone Rubber For Sealing
Our organic silicon rubber enjoys the following
advantages compare to the traditional sealing material:
1) Be able to endure
hotness and coldness. Be able to keep the rubber elasticity at the
temperature of -60℃— +250℃. It is from the experiment that the product
could have a life-span of 10 years at 120℃.
2) Be able to endure
different climates. Change nothing when exposed to outside for 15
years.
3) Adhension. Possess
excellent adhension to cement, glass and porcelain.
4) Excellent, long
time water-scattering and low water absorption.
5) Good function of
dilatability and anti-fatigue. In addition, our organic silicon
rubber changes little because of the low modulus and favorable insulation.
Our silicone rubber is composed of Part A and
Part B. Part A is make of silica gel material and Part B is made
of curing agent. The product is white fluid cream and should be
stored in shady, cool and dry place by sealed, Exposed to air for
long time and contact with water are strictly prohibited.
