  • VOC test This is a VOC test specified in the Chinese regulation GB38508-2020 (limit value of volatile organic compound (VOC) content in detergent). 2 g of each composition was weighed in a 50 mm ⁇ 30 mm weighing bottle (manufactured by AGC Technoglass Co., Ltd.) and allowed to stand in a constant temperature bath set at 105 ° C. for 4 hours. Then, it was cooled in a desiccator for 30 minutes and weighed. The VOC content percent (Wv) in the test sample was calculated by dividing the reduction by the original weight (2 g). The VOC content (X) in the test sample was calculated by the following formula.
  • HFC-43-10mee, HFO-1336mzz (Z), HFE-7200, etc. are also applicable.
  • Y Density of test sample (g / L) (criterion)
  • ⁇ X is 900 (g / L) or less.
  • X X is over 900.
  • Test Example 11 Adhesive dissolution test 0.1 g of each adhesive was applied on a SUS304 plate (manufactured by Iwata Seisakusho Co., Ltd., 35 mm x 15 mm x 0.1 mm) and allowed to stand at room temperature (about 20 ° C) for one week. , A sample to which a cured product of each resin was attached was obtained. 80 mL of each solvent composition was placed in a 100 mL beaker, sealed with aluminum foil, and heated on a hot plate to a liquid temperature of about 60 ° C. It was evaluated according to the following criteria.
  • Test Example 12 Resin cured product dissolution test In a test tube (capacity: 4 ml, 10 ⁇ 75 mm, manufactured by PYREX®) covered with aluminum foil, the amounts of each resin described below are added to 2 g of each composition. It was immersed and allowed to stand at room temperature (about 20 ° C.), and evaluated according to the following criteria.
  • the solvent composition contains p-chlorobenzotrifluoride, it is a solvent composition having a low environmental load. Further, from Test Examples 1 to 9 and 11 to 12, the solvent composition has excellent solubility of resins and the like, and is a cleaning agent, an aerosol composition, a dissolving agent for a cured resin, a coating agent for a resin, and a cured product for a resin. It had an excellent effect as an adhesive for. Further, from Test Example 10, the solvent composition was a solvent composition having a reduced VOC and a low environmental load. From Test Example 1, when the content of the component (B) was 30 parts by weight or more with respect to a total of 100 parts by weight of the solvent composition, the solubility of the uncured resin was excellent.
  • the solubility of the uncured resin was superior.
  • the content of propylene glycol monomethyl ether is 5 with respect to a total of 100 parts by weight of the solvent composition. Even when the amount was up to 20 parts by weight, the solubility of the uncured resin was superior when combined with 1-bromopropane or trans-1,2-dichloroethylene.
  • the group further comprises a nitro compound, a cyclic ether and an epoxide.
  • Example 337 in Test Example 6 the solubility of the cured product of the resin was superior in the same case.
  • the component (B) contains 1-bromopropane in a specific amount.
  • Examples 183 to 198 when a specific amount of 1-bromopropane and propylene glycol monomethyl ether is contained (Examples 199 to 222), and when a specific amount of trans-1,2-dichloroethylene and propylene glycol monomethyl ether is contained. (Examples 230 to 235) were excellent in the detergency of the flux.
