摘要:
Processes for enhancing the drainage of residual aqueous rinse from the external surfaces of plastic parts, such as auto fascia, are disclosed. The processes employ an aqueous solution of an amine functional silane compound, which when applied to the surfaces of plastic parts will not rinse off during subsequent rinse stages and will remain on the plastic parts.
摘要:
A cleaning and passivating treatment for metals comprising an amphoteric surfactant which is a caprylic acid derivative of imidazoline compounds. The treatment is substantially free of amines, alkanolamines and phosphates. The preferred treatment includes small quantities of borate ions and molybdate ions. In addition a nonionic surfactant may be added as a foam control agent.
摘要:
Methods and compositions for providing a conversion coating to a metal surface are provided. The methods comprise applying to a metal surface an aqueous composition comprising a diglycidyl ether of Bisphenol A, a fluoroacid, and a silicon compound containing a hydrolyzable group.
摘要:
A Mannich base and thiourea inhibitor composition and method of inhibiting the acid attack by aqueous hydrofluoric acid on ferrous metal surfaces, and in particular, highly reactive ferrous metal surfaces.
摘要:
Compositions and methods for cleaning and etching an aluminum surface with a low etch, low phosphate alkaline cleaner solution are disclosed. The preferred composition employs a stable combination of an alkali metal hydroxide, gluconic acid, a detergent source, an aluminum sequestrant, an oil emulsifier, a defoamer, and a hydrotrope.
摘要:
Compositions and methods for cleaning aluminum while providing oil splitting and no oxide build-up on the aluminum surface including an alkali metal silicate and a quaternary cationic surfactant in an alkaline aqueous cleaning solution.
摘要:
A composition and method for treating tin-plated ferrous metal surfaces to remove oils and other contaminants in the form of soil thereon, without etching the surface. Particularly, this invention relates to a composition and method for cleaning drawn and ironed tin-plated ferrous metal containers.
摘要:
Disclosed are methods and compositions for inhibiting the corrosion of low carbon steel in contact with aqueous systems. The composition comprises a silicon compound containing a hydrolyzable group, a complex fluoro acid, and a cross-linking agent.
