COATING SYSTEMS / SEALANTS, WATER RESIN DISPERSIONS AND METHOD FOR COATING BY ELECTRODEPOSITION

摘要

FIELD: sealants.SUBSTANCE: invention relates to coating systems / sealant resin aqueous dispersion and electrodeposition coating method using these dispersions. System coating / sealant and the sealant comprises a coating deposited over at least a portion of the coating. Coating comprises the reaction product obtained from reactants comprising phosphated epoxy and curing agent comprising an aminoplast resin. Sealant contains a sulfur polymer comprising thiol-functional polysulfide. Aqueous resin dispersion comprises a neutralized base resin composition comprising ungelatinized phosphated epoxy resin. Coating is applied by electrodeposition onto an electrically conductive substrate functioning as the anode in an electrical circuit comprising an anode and a cathode immersed in the resin dispersion.EFFECT: invention is well suited for use in various applications, such as sealant compositions aviation applications due to their fuel-proof after crosslinking.22 cl, 4 tbl, 15 ex
