1, LED lamp structure bonding:
Metal and PC / PMMA or PC and PC / PMMA adhesive seal, the use of room temperature curing one-component alcohol-based silicone sealant, aluminum, copper, stainless steel and other metals have good adhesion; electrical properties Excellent, good heat resistance, the general use of temperature range -60 ℃ ~ 200 ℃. Curing is the release of alcoholic substances, the polycarbonate (PC), optical acrylic (PMMA), copper and other materials without corrosion, in full compliance with the EU ROHS directive requirements.
2, LED lens bonding fixed:
The use of high-performance adhesive seal silicone rubber is a single component, paste, translucent, de-alcoholic room temperature vulcanized silicone rubber. Neutral curing, non-corrosive to the bonding material, after curing the formation of rubber-like elastomer, a wide range of bonding, excellent mechanical properties, good impact resistance. Heat resistance, moisture resistance and cold resistance is excellent, in high temperature and high humidity conditions still maintain good mechanical properties, not white, low yellowing. With excellent insulation, moisture, shock, resistance to corona, anti-leakage and chemical resistance and other properties.
3, LED Bulb - thermal adhesive adhesive requirements:
Thermal conductivity: 0.8 ~ 1.2
The same time as
Viscosity: Paste
High thermal conductivity, good insulation, easy to operate
● earthquake, to prevent mechanical damage, no corrosion on the substrate;
● can be repaired, easy to disassemble;
● can be used for severe temperature cycle applications;
● good then the performance, eliminating the traditional mechanical fix;
4, LED bulb - potting with plastic requirements:
1) high thermal conductivity (0.5 ~ 0.8);
2) Good foaming (viscosity 3500CPS)
3) Fast curing (mass production, 80 ° 30min)
4) Flame retardant UL94V0
