    • A water based chipping resistant paint which contains a solid component (30 to 65 weight percents) and a slowly-evaporating solvent (0.1 to 10 weight percents) as a water based dispersion substance and wherein the solid component contains a resin having a film forming function, thermally expansive fine grains and a chipping resistant material (respectively, 15 to 75 weight percents, 0.2 to 25 weight percents and 20 to 80 weight percents). The chipping resistant paint facilitates vaporization of water at the time of film formation owing to mixing of the slowly-evaporating solvent, can prevent cracking and blistering of a film due to water remaining in the film and vaporization of water remaining after the film formation, and readily form a thick film owing to an expansion effect of the thermally expansive fine grains at the stage of baking after coating, and therefore is suitable for a chipping resistant undercoat for automobiles.
    • 一种防水涂料,其含有固体成分(30〜65重量%)和缓慢蒸发的溶剂(0.1〜10重量%)作为水性分散物质,其中固体成分含有具有成膜功能的树脂 ,热膨胀细颗粒和耐崩裂材料(分别为15至75重量%,0.2至25重量%和20至80重量百分比)。 由于缓慢蒸发的溶剂的混合,耐崩裂涂料有助于在成膜时水的蒸发,可以防止由于膜中的水残留而导致的膜的起裂和起泡以及成膜后剩余的水的蒸发,以及 由于在涂布后的烘烤阶段由于热膨胀性细粒的膨胀效应而容易形成厚膜,因此适用于汽车的耐崩裂底漆。
