An aqueous electrocoating composition useful in a method of electrodeposition contains an electrodepositable resin, optionally a curing agent and a microparticulate crosslinked unsaturated polyester flatting agent. The microparticulate flatting agent provides the desired flatting effect without compromising coating properties such as corrosion resistance and flexibility.
L'invention concerne une composition aqueuse d'électrolaquage utile pour déposer des revêtements, qui contient une résine qui se dépose sous l'effet d'un courant électrique, éventuellement un agent durcissant et un agent de matité sous la forme de microparticules d'un polyester insaturé réticulé. L'agent de matité microparticulaire diminue le brillant de la surface sans effet néfaste sur les propriétés du revêtement telles que la résistance à la corrosion et la flexibilité.
