An aqueous passivation composition, having a pH of less than 3, comprising:

Passivation composition based on trivalent chromium

A water comprising, two component polyurethane dispersion adhesive comprising an anionic polyester polyurethane resin and a solvent-free liquid aliphatic polyisocyanate cross-linker. The dispersion can be reactivated one or more times for edge bonding a flexible sheet material onto a substrate having a main surface, a peripheral surface and an edge connecting the main surface and the peripheral surface.

Two-component, water-based lamination adhesive and use of the same to bond substrates and foams

This invention relates to an autodeposition bath composition comprising a nitrogen containing compound, said bath being suitable for generating a uniform autodeposition coating on two or more of ferrous, aluminum, magnesium and zinciferous multi-metal substrate surfaces, treated either sequentially or simultaneously. The invention also provides autodeposition concentrate compositions for use in the bath, methods of making and using the concentrate and bath, as well as metal articles comprising an autodeposition coating according to the invention.

Single bath autodeposition coating for combination metal substrates and methods therefor

The invention provides an improved appearance, glossy, autodepositing coating composition that maintains its desirable properties such as moisture barrier properties, although it is still able to deliver a glossy finish. No additional coatings are necessary over the instant coating to achieve a gloss. The glossy composition is accomplished by narrowing the molecular weight distribution and the molecular weight of an autodepositing epoxy dispersion coating by adding a chain transfer agent. The chain transfer agent is a thiol-containing compound made from an epoxy resin mixed with at least one ethylenically unsaturated monomer polymerized through a polymerization process, a curing agent, and a starter composition of peroxide, FeF3, and hydrofluoric acid. By eliminating the starter composition, a bath concentrate suitable for selling is manufactured.
