Light Cure UV Adhesive 23691 25mL syringe

The Loctite 3103 Flexible Light Cure Adhesive - Part # 23691 - 25ml Syringe is a single component UV/Visible light curing acrylic adhesive that works to bond polycarbonate to itself. It does not induce stress cracking when under molded stress levels. The 25ml light cure adhesive works to form a transparent bond when exposed to UV radiation and/or visible light of sufficient intensity. The adhesive 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.
