LED bulb light potting adhesive requirements

- Mar 08, 2017 -

1. LED lamp structural bonding:
Metal bonding and sealing with the PC/PMMA or PC with PC/PMMA, using room-temperature-curing one-component alcohol silicone sealant on aluminum, copper, stainless steel and other metal has good adhesiveness; superior electrical properties, good heat resistance, temperature range-60 ℃ to 200℃. Alcohol is released in the process of curing, polycarbonate (PC), optical acrylic (PMMA), copper and other materials for corrosion, in full compliance with EU ROHS directive requirements.

2. bonding of LED lens is fixed:
High performance silicone rubber adhesive seal is one component, creamy, translucent, alcohol type RTV silicone rubber. Neutral curing, bonding material is non corrosive, cured to form rubber-like elastic body, bonding a wide range of excellent mechanical properties and good impact resistance. Excellent heat resistance, moisture resistance and cold resistance at high temperature and high humidity conditions maintain good mechanical properties, not white, yellow. Excellent insulation, moisture-proof, earthquake, Corona and leakage resistance and chemical resistance properties.

3. LED bulb light-conductive adhesive requirements:
Thermal conductivity coefficient: 0.8~1.2
Viscosity: paste
Good thermal conductivity, insulation, easy operation
Seismic, prevents mechanical damage, corrosion of the substrate;
Maintainable, easy to remove;
Can be used for severe temperature cycles applications;
Good performance, eliminates traditional mechanical fixing;
4, LED bulb-potting adhesive requirements:

1. high thermal conductivity (0.5~0.8);

2. good exhaust foam (viscous 3500CPS)

3. fast curing (mass-produced, 80 ° 30min)

4. flame retardant UL94V0
