Method and apparatus for applying a curable material having variable curing characteristics to a surface in a defined application cycle which includes the steps of applying only a first slow curing component to the surface of an article at least at the beginning or at the end of an application cycle

Method and apparatus for applying a curable material having variable curing characteristics to a surface in a defined application cycle which includes the steps of applying only a first slow curing component to the surface of an article at least at the beginning or at the end of an application cycle and applying during the remaining part of the application cycle a mixture of the slow curing component and a curing agent which accelerates the curing of the first component.

A process for applying a curable material including first and second components onto the surface of an article, said first component being curable under ambient conditions after application to the surface of an article and said second component comprising a curing agent which reacts with said first

A process for applying a curable material including first and second components onto the surface of an article, said first component being curable under ambient conditions after application to the surface of an article and said second component comprising a curing agent which reacts with said first component to accelerate the curing of said first component, wherein said first and second components are selected from the group consisting of: (A) the first component being polymercapto compound and alkaline earth peroxide and the second compound being water containing polymercapto compound; (B) the first component being polyurethane prepolymer with silane end groups and the second component being a mixture of water or polyamine with a softening agent; (C) the first component being polyurethane prepolymer with isocyanate end groups and the second component being water, polyole ore polyamine in a softening agent; (D) the first component being polyurethane prepolymer with isocyanate end groups and the second component being polyurethane prepolymer with mercapto, hydroxy amino or carboxy end groups; (E) the first component being humidity curable silicon compound and the second component being dihydroxypolysiloxan paste; (F) the first compound being a mixture of an epoxy resin and a polyfunctional ketimine and the second component being diamine or water paste; (G) the first component being a mixture of an epoxy resin and molecular sieve loaded with a polyfunctional amine and said second component being diamine or water paste; (H) the first component being unsaturated polyester resin with alkaline earth peroxide and said second component being peroxide paste and (separated) cobalt napthenate; (I) the first component being a mixture of polyurethane prepolymer with mercapto end groups and an oxidation accelerator, and said second component being peroxide paste; (J) the first component being a mixture of an epoxy resin and BF3-amine-complex and said second component being BF3-etherate; and (K) the first component being a mixture of an unsaturated polyester resin and heat curable organic peroxides and said second component being co-napthenate, sulfinic acids or amines; said process consisting of an application cycle having a beginning and an end which cycle comprises the steps of applying a mixture of said first and second components to a predetermined portion of the surface of an article at the beginning of the application cycle, and thence applying during the remaining part of said application cycle only said first component.
