An adhesive composition comprising as principal components, a polymerizable component, an ambient temperature radical polymerization catalyst system and a photoinitiator. The adhesive may optionally comprise an adhesion promoter, a toughener, an epoxy, and a filler material. Further, a two-part reactive adhesive comprising, a first part comprising, (i) at least one free radical-polymerizable monomer, (ii) at least one reducing agent, and (iii) a photoinitiator, and a second part comprising an oxidizing agent that is reactive at ambient temperature with the reducing agent to produce free radicals that are capable of initiating and propagating free radical polymerization.

Dual cure adhesive formulations

A composition that includes an epoxy compound, a thiol curing agent, a catalyst and a phosphorus--containing compound having at least one P--OH group and at least one organic moiety characterized by the presence of an ethylenically unsaturated group. The composition is particularly useful as a sealer for an adhesive joint.

Thiol-cured epoxy composition

Containers for storing and/or transporting sulfur-containing compounds, and methods of deodorizing headspace gases containing sulfur-containing compounds, are disclosed. The containers include a body and a lid. In one embodiment, copper or another sulfur-deodorizing substance is attached to either the lid or upper sides of the container or is suspended in the headspace. The sulfur-deodorizing substance reacts with or adsorbs or absorbs any sulfur-containing compounds present in the headspace volume to reduce the odor in the headspace. In another embodiment, when the container include a solid or viscous liquid sulfur-containing compound, a pouch containing a sulfur-deodorizing substance is placed on top of the sulfur-containing compound. The pouch includes a liner or a sealed side in immediate contact with the solid or viscous liquid sulfur-containing compound, and a non-contacting portion providing a breathable, porous construction to permit the headspace gases to come into contact with the sulfur-deodorizing substance.

Container for storing sulfur-containing compounds

A primerless method for repairing a substrate surface that includes applying to the surface a curable filler composition that includes (i) an epoxy compound, (ii) a polythiol curing agent, and (iii) a catalyst and then curing the composition. The filler composition can also include a polyamine in addition to the catalyst.
