What key properties are required for silicone adhesives to be used in lamps?


With the improvement of people's living standards, lighting products have entered thousands of households. Most lighting products use silicone adhesives, mainly to bond, fix and seal the components of the lamps. However, to produce high-quality lighting products with good service life, the choice of adhesive is very important. I would like to introduce to you, what key properties should be paid attention to when using silicone adhesives on lighting products.


1. Yellowing resistance

Yellowing refers to the appearance of a thicker yellow color after the gel is cured. During the application process of the lamp, heat will be released. If the selected silicone adhesive cannot withstand high temperatures for a long time, it will cause aging, yellow appearance, and performance decline, which will first affect the brightness and concentration of light.


2. No corrosion

Refers to the phenomenon that the lamp components are corroded during use. Generally, common phenomena after corrosion include cracking, peeling, and discoloration. After the lamp components are bonded, they are basically in a closed state, but the silicone adhesive has not been fully cured, so small molecules will be released during the complete curing process, a long-time small molecule of gas coalescence to form a liquid attached to the inner wall of the luminaire shell. The choice of silicone adhesive on the lighting material without corrosion is also one of the key performances.


3. Torque force

Torque, this performance parameter is a very important requirement for the use of bulb lamps. Torque refers to a special torque that makes the object rotate, the test method is to use silicone adhesive bonding of the bulb's lamp holder and lampshade, fully cured, and then select the matching fixture with the lamp mounted on the torque sensor, holding the lampshade by hand (wearing protective gloves), to rotate, the force when the lampshade is loose, is the torque force. It is the bulb that needs to be twisted during installation. If the torque is small, it is easy to loosen during the installation process, so it is also one of the very important performances.


Different product structures have different requirements for the key application performance of silicone adhesives. TENSAN Silicone focuses on the research and development and production of electronic adhesive products, solves a variety of intractable problems in the use of adhesives for lighting products, and has accumulated a wealth of adhesive solutions.
