COLORED 2-CYANOACRYLATE-BASED ADHESIVE COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a 2-cyanoacrylate-based adhesive composition capable of eliminating glossiness of an adhesive cured product while inhibiting white turbidness of the cured product itself in conducting adhesion or potting by using the 2-cyanoacrylate-based adhesive composition.SOLUTION: There is provided a colored 2-cyanoacrylate-based adhesive composition containing 2-cyano acrylic acid ester (a) and a coloring agent (b), where the coloring agent (b) is 0.0025 to 10 mass% when the 2-cyanoacrylate-based adhesive composition is 100 pts.mass, a brightness Lof a cured product where the 2-cyanoacrylate-based adhesive composition is deposited on an ethylene-propylene-diene rubber with a thickness of 100 μm is 20 or less and the brightness of the cured product with an incident angle 60° is 70 or less.
