A crosslinkable composition that can be crosslinked by the addition reaction of Michael Real and resins for use in said composition

摘要

An RMA crosslinkable composition comprising at least one crosslinkable component, the at least one crosslinkable component comprising reactive components A and B each comprising at least 2 reactive groups in which the at least 2 reactive groups of component A are acidic protons (CH) in activated methylene or methine groups and the at least 2 reactive groups of component B are activated unsaturated groups (C = C) and a base catalyst (C) whose reactive components A and B are crosslinked by Michael's Addition reaction real (RMA) under the action of the base catalyst, characterized in that the at least one crosslinkable component comprising the reactive components A and B in the composition has a total hydroxy number of less than 60, preferably less than 40 and more preferably less than 20 mg of KOH / g of solids.
