Summary of information: The Derun technical team developed a solution for the application of energy-saving lamp glue based on the situation of energy-saving lamp products from a certain lighting company in Dongguan, and successfully solved the problem of glue usage. Energy saving lamps are becoming increasingly popular in social life due to their characteristics of energy conservation, high efficiency, and long lamp life. The sealing and bonding between lamp holders and lampshades, as well as the sealing and bonding between various metal lamp caps and various plastic materials, are difficult problems in practical production applications. Therefore, choosing a suitable adhesive is crucial. The HJ-731 energy-saving lamp special adhesive developed and produced by Derun Rubber Industry has solved various sealing problems in the energy-saving lamp industry
In September 2018, the R&D and procurement departments of a lighting company in Dongguan contacted us by phone, hoping that we could help solve the problems of energy-saving lamp sealing, bonding, high and low temperature resistance, electronic component protection, and shock resistance
Develop a solution based on the product structure and usage conditions introduced by the current customer:
1、 Based on the product structure, we first address the bonding and sealing issues between glass and plastic, as well as aluminum and plastic:
The adhesive properties need to meet the following requirements:
1. Bond strength between metal and plastic
2. It has characteristics such as high and low temperature resistance, aging resistance, and moisture resistance Recommended product HJ-731W white flowing energy-saving lamp special adhesive
The reasons are as follows:
1. Adhesion has a high bonding strength between metal and plastic, as well as between plastic and glass.
2. Temperature resistance High and low temperature resistance -60-200 degrees
3. Waterproof, waterproof, and sealed with a waterproof grade of Ip68, with outstanding moisture-proof ability 4. Easy to operate with different packaging options, both manual and dispensing machines.
5. Designed with a lifespan of 5-10 years, meeting the needs of product replacement
6. Environmentally friendly adhesive has passed EU ROSH2.0 environmental monitoring
2、 Solve the protection and shock resistance of electronic components on circuit boards
The adhesive properties need to meet the following requirements:
1. Good waterproof and insulation resistance
2. The adhesive layer is required to be soft and easy to repair
3. Excellent aging resistance, with a service life of 5-7 years

4. Prevent vibration of electronic components and glue detachment
Recommended product HJHJ-101B high-performance silicone potting adhesive
Reason for recommendation:
1. Excellent adhesion performance for metals, plastics, and circuit boards

2. Temperature resistance High and low temperature resistance -60-200 degrees
3. Moderate leveling performance, viscosity, self leveling without bubbles, and good surface glossiness
4. Easy to operate, suitable for sealing machine packaging, improving production efficiency
5. Weathering resistance, aging resistance, hydrochloric acid resistance, and salt spray resistance tests
6. Environmental Protection Passes EU ROSH2.0 Environmental Monitoring
