Appendix A
Construction Reference
(Reference)
A1 The construction is mainly spraying. The paint should be stirred before construction. The thinner can be ZBG52003X-4 amino thinner or a mixed solvent of xylene and butanol (4:1).
A2 When used as a glazing, the paint film on the surface of the object to be coated should be gently polished and cleaned with sandpaper before use. A3 To make the paint film bright and full, the baking temperature should not be too high. A4 After spraying, the construction parts must be left to stand for more than 5 minutes before baking. Additional notes:
This standard is proposed by the Science and Technology Department of the Ministry of Chemical Industry of the People's Republic of China. This standard is under the jurisdiction of the National Technical Committee for Standardization of Paints and Pigments. This standard is drafted by the Secretariat of the National Technical Committee for Standardization of Paint Products. The main drafter of this standard is Sun Jiaqi.
From the date of implementation of this standard, the original professional standard ZBG51042-87 "A01-1, A01-2 Amino Baking Thousand Varnishes" of the People's Republic of China will be invalid.
