Introduce:

• This adhesive is suitable with curing methods by UV light and can be activated by visible light;
• It’s just one component base on modified epoxy resin, low viscosity.

Application range:

• Multipurpose, especially for tensile-equalizing bonding and sealing, in particular in case of high-temperature fluctuations at the component;

• For bonding of metal, glass, plastic, and coating materials, fixing or sealing of electronic components;
• Suitable for the bonding of opaque components through preactivation;
• Easy to control due to yellowish fluorescence color;
• Temperature range for use of -40 ~ +150 ^oC, depending on the application, other limits may be reasonable;
• Compliant with RoHS directive 2015/863/EU;
• Successfully tested according to UL 94 HB.

 Curing:

• Curing with UV light or visible in a wavelength range of 320 ~ 550 nm;
• For preactivation, only visible light in a wavelength range of 400 ~ 550 nm can be used;
• After irradiation curing until final strength within 24h at room temperature;
• Dependent on materials thickness and absorption, adhesive layer thickness, lamp type, and distance irradiation, curing parameters may be changing.
