Liyang kangdawei industrial CO.,LTD
KDW-1807 is one-component condensed sealant, which is cured from the outside to the inside by absorbing moisture in the air, so the curing time could be reduced by improving environment temperature and humidity. It could be used in all kinds of electronic component of adhesion and sealing. It has excellent electrical insulation property, dampproof, anticorona, the function of cushion, and good high and low temperature resistance performance. It could be long-term used in indoor and outdoor products of adhesion, sealing, waterproofing and insulation protection.
Application.
1. Automobile and other lamps
2. Power supply and control module
3. Electronic components of fixing, instruments of adhesion and sealing.
Characters.
1. One-component dealcoholization condensation silicone sealant
2. Paste, easy to process, strong maneuverability
3. Low shrinkage rate, no corrosion, no stress
4. Excellent high temperature electrical insulation and stability
5. Excellent thermal conductivity.

Packing.
1.100ml/sausage, 100sausage/carton;
2.300ml/pipe, 25pipe/carton; 330ml/pipe, 25pipe/carton;
also could be customized.
Storage and transportation.
1. Avoid light and heat, keep ventilation and dry (could be transported and stored as non-dangerous goods )
2. The shelf life would be 6 months at 25℃.
Operation process.
1. Clean the surface: clean the surface of adherend or coated object, remove rust, dirt and greasy dirt, etc. (dirt and greasy dirt would affect adhesion performance)
2. Sizing: use knife to cut the head of plastic pipe, put on long nose, extrude the adhesive on clean surface, and fix the adherend.
3. Curing: put the adhesive units in the air, whether it is completely cured is depending on the thickness. (2mm thickness, 25℃, 50% humidity, could be completely cured after 24 hours )
4. Notes: Seal and store the remaining sealant immediately after use. Remove the crust on the head when using again, which would not affect normal working.
