Examples
Embodiment 1
[0141] Mix 30 parts of liquid A containing epoxy resin and compound (P) with a branched thiol group prepared in preparation example A1, and 4 parts of liquid B containing curing auxiliary agent prepared in preparation example B1 to obtain a ring Oxygen resin coating composition. This composition was coated on the polished steel plate using ANEST IWATA Co., Ltd. EASPRE-W-101. Adjust the air flow and valve opening during coating so that the film thickness after drying is about 30 microns. After coating, it was dried and cured at 25°C. As a result, it took 1 hour until the coating film was touched without leaving fingerprints (finger-touch drying time), and a good coating film was obtained.
Embodiment 2
[0143]Use A2 that has reduced the amount of the compound (P) with branched chain thiol groups in A liquid and 10 parts of B2 liquid that added polyamide amine curing agent in B liquid, in addition, by and embodiment 1 The same operation is carried out for coating, drying and curing. The dry-to-touch time was 4 hours, and a good coating film was obtained.
Embodiment 3～4
[0145] Coating, drying, and curing were performed in the same manner as in Examples 1 and 2, except that drying and curing were performed at 5°C. The dry-to-touch time was 5 to 10 hours, and it can be seen that it cured in a short time even at a low temperature.
