The present invention relates to an epoxy composition including
- a waterborne hardener component containing an amine functional adduct, which is a reaction product of at least one polyether amine, at least one polyalkylene amine, at least one arylaliphatic or cycloaliphatic amine, at least one polyether epoxy resin and at least one aromatic liquid epoxy resin,
- a resin component containing at least one liquid epoxy resin and
- mineral fillers,
wherein the composition contains mineral fillers in the range of 85 to 95 weight-% based on the total solids of the composition.
The inventive epoxy composition enables floor coatings with low emission, low shrinkage and high impact resistance, which can be applied in a layer thickness of 1 to 3 mm or more in one step, cure to a decorative, faultless and glossy surface without the need to be overcoated and generate a low enough heat upon burning to fulfill the fire classification A2fl according to EN 13501-1.
本发明涉及一种环氧树脂组合物,包括
- 一种水性固化剂组分,含有胺官能加合物,该加合物是至少一种聚醚胺、至少一种聚亚烷基胺、至少一种芳脂族或环脂族胺、至少一种聚醚环氧树脂和至少一种芳香族液体环氧树脂的反应产物、
- 含有至少一种液体环氧树脂和矿物填料的树脂组分
- 矿物填料、
其中,根据组合物的总固体含量,矿物填料的含量在 85 至 95 重量%之间。
本发明的环氧树脂组合物可以制成低排放、低收缩和高抗冲击性的地坪涂料,可以一次涂抹 1 至 3 毫米或更厚的涂层,固化后表面具有装饰性、无瑕疵和光泽,无需再涂覆,燃烧时产生的热量很低,符合 EN 13501-1 的 A2fl 防火等级。
