水性涂料用组合物及二液固化型水性涂料试剂盒
摘要：
本发明提供一种水性涂料用组合物和二液固化型水性涂料试剂盒，该水性涂料用组合物含有长期的贮藏稳定性优异、而且掺有掺在涂料中的各种成分时的贮藏稳定性也优异的含氟共聚物，该二液固化型水性涂料试剂盒将所述水性涂料用组合物和固化剂组合物组合使用，贮藏稳定性优异。水性涂料用组合物的特征在于，含有由含氟共聚物(A)构成的平均粒径50～100nm的粒子和水，其pH为7.0～9.5，所述含氟共聚物(A)中，相对于共聚物中所含有的全部聚合单元，以40～60摩尔％的比例含有氟代烯烃聚合单元(a1)、以1～5摩尔％的比例含有具有羧基的聚合单元(a2)、该羧基的95～100摩尔％成为羧酸盐基、以4～30摩尔％的比例含有具有羧基以外的交联性基团的聚合单元(a3)、以3～50摩尔％的比例含有侧链上具有含醚键或酯键的基团的聚合单元(a4)。
摘要（英）：

Provided are: a composition for an aqueous coating material, which contains a fluorine-containing copolymer and has excellent long-term storage stability and excellent storage stability in cases where various components to be added into coating materials are added therein; and a two pack curable aqueous coating material kit having excellent storage stability, in which the composition for an aqueous coating material and a curing agent composition are used in combination. A composition for an aqueous coating material, which is characterized by containing water and particles that are formed from a fluorine-containing copolymer (A) and have an average particle diameter of 50-100 nm and by having a pH of 7.0-9.5. The fluorine-containing copolymer (A) contains, relative to all the polymerization units contained in the copolymer: 40-60% by mole of fluoroolefin polymerization units (a1); 1-5% by mole of polymerization units (a2) that have carboxyl groups, 95-100% by mole of which have changed into carboxylate groups; 4-30% by mole of polymerization units (a3) that have crosslinkable groups other than carboxyl groups; and 3-50% by mole of polymerization units (a4) that have groups, each of which has an ether bond or an ester bond in a side chain.
