Abstract: Curable sealant compositions comprise the components: a) x weight percent of at least one polythiol; b) y weight percent of at least one unsaturated compound having at least two non-aromatic carbon-carbon double bonds, at least one carbon-carbon triple bond, or a combination thereof; c) from 0.01 to 8 weight percent of at least one organoborane-amine complex; d) from 0.05 to 10 weight percent of at least one organic peroxide; and e) from 0.01 to 10 weight percent of a photoinitiator system capable of generating free radicals upon exposure to actinic radiation. Each of x and y represents a positive real number. The sum x+y is in the range of 72 to 99. The weight percent ranges of the components a)-e) are based on the total weight of the components a)-e). A seal cap including the curable sealant composition and methods of making and using the curable sealant compositions are also disclosed.

Abstract: Methods and apparatuses for screen or stencil printing a pattern on a substrate are provided. The substrate (2) has its major surface in contact with a first major surface (112) of a stencil shell (111) having apertures (116). A coating material is disposed onto the second major surface (114) of the stencil shell (111) to flow through the apertures (116) to contact the substrate (2), where the coating material is at least partially cured. The substrate (2) is separated (C) from the first major surface (112) of the stencil shell (111) after the curing (142) and a pattern (42) of the at-least-partially-cured coating material is formed on the substrate (2).
