LOCTITE ABLESTIK 45W1 / CAT 15: Black Opaque Epoxy for UV & Security Potting
Loctite Ablestik 45 W1 when combined with the supplied Catalyst 15 creates a two part black epoxy adhesive and is designed for use where shock and peel resistance are desired.
LOCTITE ABLESTIK 45W1 (with Catalyst 15) is a jet-black, opaque structural adhesive designed to provide both flexibility and visual shielding. The "W1" pigmentation is specifically engineered to hide bond lines and prevent the reverse-engineering of circuit layouts by making the encapsulated components invisible. This black resin offers superior resistance to thermal shock and mechanical impact while blocking UV light exposure.
