example 1

[0089] 92 parts by weight of D.E.R. TM 331 and 8 parts by weight cardanol were mixed in a flask under nitrogen. After the mixture reached 90° C., 200 ppm ethyltriphenylphosphonium acetate (70 wt. % in methanol) was added as a catalyst. The mixture was heated to 180°C and maintained at this temperature for 2 hours. Epoxy resin A is obtained. The product contained about 81 wt.% compound (I) and about 19 wt.% compound (V).

example 2

[0091] 85 parts by weight of D.E.R. TM 331. 7.5 parts by weight of cardanol and 7.5 parts by weight of cardol were mixed under nitrogen. After the mixture reached 90° C., 300 ppm ethyltriphenylphosphonium acetate (70 wt. % in methanol) was added as a catalyst. The mixture was heated to 170°C and maintained at this temperature for 3 hours. Obtain epoxy resin B. The product contained about 57 wt.% compound (I), 17 wt.% compound (V) and 26 wt.% compound (VI).

Abstract

This invention relates to a cardanol modified epoxy resin composition, especially, relates to a cardanol and / or dihydric phenol modified epoxy resin composition, a process making thereof and its application in a low VOC high solids coating, and a low VOC waterborne coating.

Description

technical field [0001] The present invention relates to a kind of epoxy resin composition modified by cardanol, especially relate to the epoxy resin composition modified by cardanol and / or dihydric phenol and its low volatile organic compound (VOC) high solid coating layer and application in waterborne coatings. Background technique [0002] Epoxy-based anti-corrosion coatings are widely used to protect metal and concrete substrates. Due to the increasing awareness of environmental protection and stringent environmental requirements, low VOC coating systems are attracting more and more attention from paint manufacturers and end customers. From a technical point of view, one way to achieve low VOC coatings is to use low viscosity epoxies to prepare the coatings with reduced solvent addition. [0003] In the past, solid epoxies (such as D.E.R. TM 671 (commercially available from the Dow Chemical Company)) is widely used in anti-corrosion coatings. However, D.E.R. TM 671...
