The present invention concerns low-odor, low-viscosity hardeners for epoxy resins, including an amine with at least one amino group of formula (I) and an amine with at least one amino group of formula (II), wherein the amino groups of formulas (I) and (II) are present in a particular ratio.
These hardeners harden quickly with epoxy resins and without blushing to form films of high hardness and good resistance. They are especially suitable for low-emission coatings.
本发明涉及低气味、低粘度的环氧树脂固化剂,包括至少具有公式(I)中至少一种氨基基团的胺和至少具有公式(II)中至少一种氨基基团的胺,其中公式(I)和(II)的氨基基团以特定比例存在。这些固化剂能够快速与环氧树脂固化,不会出现发白现象,形成硬度高、耐磨性好的薄膜,特别适用于低排放涂料。
