CA 2235502

To obtain antistatic agents, adhesives and coatings with high antistatic properties under low ambient humidity and temperature, a quaternary ammonium compound of the formula: (see fig. I) (wherein R1, R2 and R3 are each a C1-C5 alkyl group and R4 is a C1-C2 alkyl group) is employed as an antistatic agent. The coating is based on, for example, an acrylic copolymer and the adhesive is based on, for example, a urethane containing a polyisocyanate component and a polyol component.

Pour obtenir des produits, des adhésifs et des revêtements fortement antistatiques dans des conditions d'humidité ambiante et de température faibles, on utilise comme agent antistatique un composé d'ammonium quaternaire de formule (voir fig. I) (où R1, R2 et R3 sont chacun un groupe alkyle C1-C5, R4 étant un groupe alkyle C1-C2). Le revêtement est par exemple à base d'un copolymère acrylique, et l'adhésif est par exemple à base d'uréthane renfermant un constituant de type polyisocyanate et un constituant de type polyol.
