An aqueous polymer composition which when in the form of a film shows excellent elongation at break comprising (i) 5 to 30 wt. % of polyurethane where the acid value of the polyurethane is between 3 to 40 mg KOH/g; (ii) 70 to 95 wt. % of vinyl polymer comprising 20 to 90 wt. % of vinyl polymer with Tg&#x3c;20&#xb0; C.; 10 to 80 wt. % of vinyl polymer with Tg&#x2265;20&#xb0; C.; where at least one of the vinyl polymers contains acid functional groups with acid value in the range of from 15 and 240 mg KOH/g.

Aqueous composition with improved elongation at break

An aqueous coating composition, which when in the form of a film exhibits an MVTR of &#x2266;500 g/m/24 h comprising 20 to 80 wt % of a polyurethane A with an acid value of 8 to 40 mg KOH/g and a hard segment content &#x2267;40 wt %, a ring structure content &#x2267;48 wt % and 80 to 20 wt % of a vinyl polymer B with a Tg&#x2267;20&#xb0; C.

Stain resistant urethane-vinyl aqueous coating compositions

Disclosed is a method to provide a metal wire with a coating system comprising a primer and a topcoat, particularly a hydrophilic, lubricious topcoat. The method comprises applying directly onto the wire metal a primer coating composition, which is an aqueous coating composition comprising a multiphase vinyl polymer, the polymer comprising a first phase having a Tg in the range of from &#x2212;20&#xb0; C. to 40&#xb0; C. and a hard phase having a Tg in the range of from 25&#xb0; C. to 120&#xb0; C. The primer has good adhesion to both the metal surface and the topcoat, and provides the eventual coating system with, inter alia, a good flexibility.

Primer for coating coiled wires

Aqueous coating composition comprising a blend of 20 to 60 wt % of a multistage vinyl polymer (A) comprising 5 to 40 wt % of at least one hard polymer stage (i) having a Tg&#x2267;50&#xb0; C. and 95 to 60 wt % of at least one soft polymer stage (ii) having a Tg&#x2266;&#x2212;5&#xb0; C.; and 80 to 40 wt % of a vinyl oligomer-polymer (B) comprising 15 to 50 wt % of at least one alkaline soluble oligomer (iii) and 85 to 50 wt % of at least one vinyl polymer (iv) having a Tg in the range of from &#x2212;20 to 30&#xb0; C.
