Henkel not only offers Macromelt hot-melt low-pressure moulding technology for protecting delicate electronic components, but also a choice of encapsulating compounds for tough specifications relating to temperature resistance.
For this reason Loctite silicones are already popular for sealing lighting products against moisture, solvents and environmental conditions. And with the addition of Loctite SI 5700 to the range another important benefit is now available for such applications.
Unlike other products that can yellow with exposure to UV light and elevated temperatures, the new Loctite SI 5700 retains its colourless clarity. This encapsulating compound has been developed specifically for tasks such as sealing energy efficient LED arrays, advertising signs, illuminated lettering, lighting façades and other outdoor applications.
This is a highly transparent, two-compound silicone which offers good adhesion on a wide range of substrates such as metal, glass and plastics. The moulding produced with this material is bubble-free, providing OEMs with the competitive advantage of products that look good throughout their service life.
Loctite SI 5700 joins the wide range of potting and encapsulating compounds from Henkel based on epoxy, hot melt, silicone and urethane technologies. Desired viscosity, operating temperature, chemical resistance, thermal conductivity and flame retardance determine which product is most suited to the task.
