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.
