silicone sealant is a one-component,neutral-curing silicone sealant exhibiting superior performance in applications where sealing openings in walls and floors are needed to control the spread of fire, smoke, toxic gasses, and water during fire conditions.
It is an ideal material designed for use in fire-stop systems for through penetrations and joints. This product excels in applications where greater water resistance is required e.g. curtain wall, building facade, expansion/pipe and cable joints.
Feature
The RTV silicone rubber is a neutral and transparent one-component RTV silicone rubber to absorb moisture in the air at room temperature curing . With non-toxic , non-polluting , non-corrosive , anti-aging , moisture ,
excellent electrical insulation and arc resistance characteristics, and have good adhesive properties . Long-term use in the temperature range of -60 C - 200 C, stable performance, mainly used for perfusion sealed
electronic components , play a moisture-proof , sealed , shock , so as to achieve stable performance of the role .
Uses:
Since the curing of the RTV silicone rubber -like elastic body is transparent , the need for a transparent
optical adhesive seal material , because a certain adhesion can be used for encapsulating electronic components
and small output transformer and TV industry sealed against moisture , seal , so as to achieve stable
performance seismic effects . SCR table can be used as protection , optical instruments require transparent
adhesive seal , electronics, communications equipment moisture seal to protect the paint coating , transistors
and silicon diodes and protection coatings.
Usage:
After the components for general cleaning , cutting nozzle sleeve beak , extrusion gel , adhesive bonding.
At room temperature 25 C, 50% humidity environment , 24 hours curing depth of 2-3 mm. As gluing area,
longer curing adhesive thickness , the longer the storage time at room temperature , the better the adhesion .
Components such as temperature may be placed in the fully cured layer 50 C - 150 C drying in a room
temperature according to any of 4 to 12 hours , and the adhesion strength can reach better results .
Note:
1 , the temperature component may be cured at room temperature , then at 50 C- 100 C, moist oven for
4 to 8 hours , which turns off the low-molecular material , sufficiently cured to ensure that the adhesive performance .
2 , when the RTV silicone rubber potting , a thickness of not much accumulation , if 3mm, can be layered watering
gradually curing method , the greater the accumulation of glue thickness , the longer the time to fully cure .
The RTV silicone rubber after use , the hose should be tightly closed , save again .
