A redox curable composition, methods for manufacturing same and uses thereof are disclosed. The redox curable composition is useful as a pre-applied adhesive. The redox curable composition is solid at room temperature, may be heated for application to a substrate, and cools to form a dry-to-touch adhesive layer on said substrate, which may be activated when required by mating with another substrate and exposure to an anaerobic environment. The composition is particularly suited to manufacturing complex products, such as mobile phones, computers and circuits.

Redox curable compositions and methods of manufacture thereof

A curable primer composition comprising:(a) a curable component such as methacrylate; (b) a cure initiating component; and (c) a polymer material selected from the group consisting of: (i) block polymers represented by S-A-S where S is polystyrene and A stands for a polymer or copolymer formed from one or more of ethylene, propylene, butylene, and styrene, which are optionally substituted with carboxylic acid or maleic anhydride; provided that when A comprises styrene then A is a copolymer of styrene with at least one of ethylene, propylene and butylene, and is optionally substituted with carboxylic acid or maleic anhydride; and (ii) polystyrene-poly(ethylene-propylene) ('SEP'); and (iii) any combination of said polymer materials. The composition is applied to a part then photocured. It is dry to touch. Thereafter a thermoplastic material such as a polyolefin is overmolded (e.g. injection molded) over the applied composition. It enhances bond strength of the polyolefin to the part.

Primer compositions for injection molding

Cyanoacrylate compositions, methods for forming same, and applications thereof are disclosed. The compositions demonstrate improved thermal ageing performance, including improved tensile strength performance after heat ageing in high humidity.

Cyanoacrylate compositions

A cyanoacrylate composition with thermoplastic polyurethane, formulated as a non-flowable soft solid or semi solid mass, for example in stick form, is reported.

Solid cyanoacrylate compositions

Cyanoacrylate compositions that include a cyanoacrylate component, a rubber toughening component, a component containing at least two (meth)acrylate functional groups and an anhydride component are provided.

Cyanoacrylate compositions that include, in addition to an allyl-2-cyanoacrylate, a rubber toughening component and a component functionalized with at least two blocked hydroxyl groups are provided.

An anaerobically curable composition comprising an anaerobically curable component that is a combination of a solid resin component and a solid anaerobically curable monomer. A curing component for curing the anaerobically curable component is included. The composition is solid and has a melting point in the range from 30&#xb0; C. to 100&#xb0; C. The composition is dry to touch and can be used to form articles of manufacture such as a tape, an elongate filament, a gasket, a patch.

Anaerobically curable compositions

Two part cyanoacrylate/cationically curable adhesive systems are provided, which contain vinyl ethers.

Two-part, cyanoacrylate/cationically curable adhesive systems
