Light UV Cure Adhesive 23692 1 Liter Bottle

The Loctite 3103 Flexible Light Cure Adhesive - Part # 23692 - 1 Liter Bottle is a single component, thixotropic, acrylic, flexible, low modulus, medium viscosity, UV/visible light cure adhesive that helps in rapid curing. This adhesive forms a flexible and transparent bond when exposed to ultraviolet radiation and/or visible light of sufficient intensity. The adhesive reduces stress cracking on plastics and also cures with the help of UV blocked and tinted substrates.

The adhesive works well for a wide variety of substrates, which includes plastic, glass, ceramic and metals. It also works well for sealing, gap filling and potting.

When to use the adhesive:

Typically for bonding polycarbonate to itself, while not inducing stress cracking under typical molded stress levels
