Abstract:
Chromate-free and metal phosphate free treatments and compositions for aPPlying a conversion or passivation coating for metals, more particularly, steel, zinc coated steel, and aluminum surfaces. The methods of the invention comprise contacting the requisite metal surface with a treatment composition comprising a member or members comprising one or more Group IV B elements, fluoride, and a phosphonic acid or phosphonate. Optionally, a silane may be added as a treatment component .
Abstract:
Conversion and passivation coatings and methods for treating metal surfaces such as steel and aluminum are disclosed. The coating compositions comprise a silane and a stabilizing agent. The methods herein comprise contacting the requisite metal surface with the coating composition.
Abstract:
The present invention related to a novel continuous process for the manufacture of hindered, ester-substituted phenols using 2,6-dialkylphenol a basic catalyst and acrylate esters.
Abstract:
An oil-in-water emulsion composition remover is disclosed. The compositions comprise a solvent, water and a surfactant. The removers are useful in removing non-aqueous and aqueous coatings, waxes, greases, and the like, from substrates to which the coatings, waxes, greases, and the like, have been applied.
