ONE-PART WOODWORKING ADHESIVE COMPOSITION

An adhesive composition that includes a) an emulsion that includes a multi stage polymer that includes a first stage polymer having a Tg from -20 °C to 90 °C and including from about 0.5 % by weight to about 3 % by weight latent crosslinking monomer based on the first stage monomer weight, and a se...

Beschreibung
Zusammenfassung:	An adhesive composition that includes a) an emulsion that includes a multi stage polymer that includes a first stage polymer having a Tg from -20 °C to 90 °C and including from about 0.5 % by weight to about 3 % by weight latent crosslinking monomer based on the first stage monomer weight, and a second stage polymer having a Tg from 40 °C to 140 °C, the second stage polymer being different from the first stage polymer, b) formaldehyde-based crosslinking agent, and c) catalyst, the composition being capable of passing the DIN EN 204 Test Method. Composition adhésive comprenant a) une émulsion faite d'un polymère multi-étapes dont la Tg est comprise entre -20 DEG C et 90 DEG C et comprenant en poids entre environ 0,5 % et environ 3 % d'un monomère de réticulation latent basé sur la masse du monomère de premier étape et un monomère de deuxième étape dont la Tg est comprise entre 40 DEG C et 140 DEG C, le monomère de deuxième étape étant différent du monomère de premier étape, b) un agent réticulant à base de formaldéhyde, et c) un catalyseur. Cette composition répond au exigences de la méthode d'essai DIN EN 204.
