Appendix A
Construction reference
(reference)
A1Before use, components A and B must be fully stirred and evenly mixed, strictly in accordance with the prescribed proportion, and used up within 8 hours. A2The surface of the object to be painted must be cleaned before painting, so that the surface is free of rust, oil, ash and water, reaching Sa2-level or St3 level, in order to increase
the adhesion and durability of the paint film.
A3The paint can be applied by brushing, dipping, rolling and spraying. It is strictly forbidden to mix with different types of paint and thinners. When the paint liquid is viscous, use the matching thinner to dilute it.
A4When this paint exceeds the storage period, it can be tested according to the items of this standard. If the results meet the requirements, it can still be used. Additional remarks:
This standard is proposed by the Technical Supervision 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 Coatings and Pigments. This standard was drafted by the Chemical Plant of the Research Institute of Jilin Chemical Industry Corporation and the Jiangsu Lanling Anticorrosion Material Factory. The Ministry of Chemical Industry's Changzhou Coating Chemical Research Institute, Tianjin Dengta Coating Co., Ltd., Longkou Anticorrosion Installation Engineering Corporation Chemical Plant, Tongling Nonferrous Anticorrosion and Waterproofing Material Factory, Chengdu Sifang Anticorrosion and Insulation Engineering Co., Ltd., Shanghai Jianke Institute New Building Materials Factory, Shijiazhuang Special Paint and Ink Factory, Henan Changyuan Anticorrosion Material Factory, and Tianjin Seawater Desalination Research Institute participated in the drafting. The main drafters of this standard are Liu Weicheng, Liu Zhongkun, Wang Yujie, Chen Jiangang, and Su Mei. From the date of implementation of this standard, the former Ministry of Chemical Industry of the People's Republic of China Standard HG/T2241-91 "J52-81 and J52-61 Chlorosulfonated Polyethylene Anticorrosion Coatings" will be invalidated.
