LED Curing Adhesive System
Description
The LED405FL3 is a flexible one component, LED curing adhesive system with good optical clarity and a refractive index of 1.51. Its flexibility allows for stress minimization especially when bonding substrates with different coefficients of thermal expansion. It also uses a fluorescent dye for easy visual inspection.
This no-mix system cures fully tack-free upon exposure to a 405 nm wavelength light source without any oxygen inhibition. In thinner sections, full cures can be achieved in 30 to 45 seconds. The rate of cure depends upon the intensity of the light source, the thickness of the adhesive layer, and the distance from the light to the adhesive. LED405FL3 is serviceable from -100 to +250°F (-73.3 to +121.1°C). It cures with a hardness of around 5 to 15 Shore D at room temperature. Additional performance properties include electrical insulation as well as resistance to thermal cycling, shock, and vibration.
LED405FL3 is a low viscosity system that may be used for small potting and encapsulation applications, assuming that there are no shadows or concealed areas. This solvent free, RoHS compliant compound is available in syringes, ½ pint, pint, and quart containers.
