Features
GD-443 is a one-component RTV silicone rubber dealcoholized faster speed table dry and fully vulcanized flammability rating of UL- HB level,
Particularly suitable for industrial production lines. The product vulcanized metal non-corrosive, easy to use, and excellent long-term use
in the range of -60~200℃ milk UV weathering resistance and good electrical insulation properties and other characteristics. Can be used
as electronic components,industrial electrical equipment,coating, bonding,sealing(heat sink adhesive and screw cap). The moisture-proof,
shock-proof, insulated and able to withstand the impact of the hot and cold alternating coated components very good protection package.

Usage
Adhesive seal
To be with ethanol or acetone the coated components surface dust, oil, and other scrub clean upon solvent
evaporation GD-443 will be a small amount evenly applied to the adhesive surface, then the bonding composite
to next a certain pressure to be placed 72 hours, the mixture was allowed to stand at room temperature for 24
hours can be moved, and completely curing takes one week.
Thick layer of seal
GD-443 sulfide gradual rely on contact with moisture in the air from outside to inside, the best batches construction
for more than 5mm coating ,that each scratch about 3mm sulfide before continuing to the next construction.
