Abstract: A method of applying coating composition is described in which the coating composition comprises a multi-stage emulsion polymer that is both radiation curable, removable and includes chemically reactive functional groups in the coating that react with one or more conventional chemical stripping agents, effecting the removal of the coating from a substrate. The UV curable and removable composition is included within one or more layers applied on top of a substrate or on top of a base coat that itself is disposed on top of a substrate.

Abstract: A two-component floor coating composition comprising: (a) an aqueous solution of a polyhydroxypolyacrylate having acid groups neutralized with a tertiary amine containing at least two hydroxy groups; said solution comprising an organic solvent; and (b) an aliphatic polyisocyanate.

Abstract: Aqueous coating compositions containing (1) a first polymer containing reactive functional groups with a selected level of carboxylic acid functionality and (2) a polyfunctional crosslinker agent containing functional groups that are reactive with appropriate functional groups of the first polymer, are disclosed. The two-component polymer compositions provide a combination of durability and ready removability of the final coating after curing. Two-component polymer compositions based on the first polymer containing hydroxyl functionality in addition to carboxylic acid functionality and use of a polyisocyanate as the polyfunctional crosslinker agent are especially useful as floor polish compositions.

Abstract: A method for preparing multi-layer protective coatings having enhanced durability with easy removability under conventional stripping conditions is disclosed. The invention is based on applying to a substrate, a first-coating composition that is removable, followed by application of a second-coating composition that is highly durable but not readily removable. Preferred second-coating compositions are based on polymers that provide highly crosslinked ‘non-removable’ (under conventional stripping conditions) coatings if used alone. The resultant multi-layer coating compositions provide enhanced detergent resistance while retaining easy overall removability properties.

The UV curable and removable composition is included within one or more layers applied on top of a substrate or on top of a base coat that itself is disposed on top of a substrate.
