Abstract
An acrylate composition, especially useful for producing conformal coatings on circuit board assemblies, includes a photoinitiator and an air-curing system, the latter being comprised of a compound having multiple allyloxy groups in its molecule and a transition metal salt catalyst. The composition is highly stable against auto-induced reaction in the absence of oxygen and at room temperature; it contains no active oxygen catalyst and no nonreactive diluent, and is advantageously formulated as a one-part product.
