KDW-1536 deketoximized silicone sealant is one kind of neutral silicone sealing materials which cured by absorbing the moisture in the air at room temperature. It has good adhesion and sealing performance to most of materials, usually used in solar cell component aluminum frame adhesion and sealing, junction box adhesion, and prevent crystalline silicone and polycrystalline silicone from pollution and oxidation.After KDW-1536 silicone sealant cured, the elastomer has following chracters:
1.Resistance to moisture, dirt and other atmosphere components
2.Alleviating mechanical stress and tension caused by machine, thermal shock and vibration
3.Excellent electric insulation performance and anticorona performance
4.Excellent outdoor aging performance, and the service life could be 20~30 years
5.Stable mechanical and electrical performance at the temperature between -60~260℃

Ps: All data was measured by testing after 7 days curing under the condition of 25℃ and 55%RH.
1.Clean the surface: clean the surface of adherend or coated object, remove rust, dirt and greasy dirt, etc.
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, and it could be used after 24 hour curing at room temperature.
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.
