The dual-cure hardener blends are based on a blend of at least one amine-based curing agent and at least one phenolic curing agent.
A blend of two hardener components, an amine and an imidazole component is added to the potting compound as a hardener, both hardener components having a solid form at ambient temperature.
The epoxy resin composition comprises the epoxy resin and a hardener.
Depending on the particular resin system, the novel hardeners may also be used in combination with further known co-hardeners or accelerants.
Additionally, a use of a polymer dispersion or a mixture of different polymer dispersions in a hardener for use in a method for separate application of adhesive and hardener is disclosed.
As the hardening agent, use is made of a phenolic resin hardening agent with biphenyl skeleton.
The resin composition also can include a hardening composition including a water control hardening agent.
The first layer contains a cationic hardening agent and an epoxy resin, and the second layer contains a radical hardening agent, an acrylic resin and an epoxy compound.
This layer also includes a water-soluble binder and a silane hardening agent.
The compositions include an aggregate, a liquid resole resin, and a magnesium hardening agent.
An acid anhydride curing agent or phenol curing agent is used for the curing agent, and solder particles are used for the conductive particles.
The thermosetting elastomer can contain a curing agent.
The composition further includes a curing agent and a cure catalyst so that it can be molded and quick-cured.
In one embodiment, the dielectric substrate is comprised of an epoxy resin made with a curing agent that is other than an amine curing agent.

The composition includes a film-forming binder comprising a carbamate material, a curing agent, typically a monomeric melamine curing agent, and a hydroxy functional silane component.
In either aspect, the second curing co-agent is an organic compound including at least one terminal alkene, with the proviso that the second curing co-agent is not a member of the group of first curing co-agents.
The flame-retardant adhesive resin composition comprises: (A) a phenoxy resin; (B) an epoxy resin; (C) a curing agent; and (D) a curing-accelerating agent as essential components.
A curing-composite film comprising an insulating polymer and a curing agent is formed on the outermost layer of an inner sheet.
A novel water compatible curing agent for epoxy resins is provided.
The curing of the resin is controlled by filling the curing agent into micropores or microporous particles which are dispersed throughout the resin.
Such amine-terminated curing agent can also be capped with a monoepoxy.
The resin composition comprises: an epoxylated polyphenylene oxide resin; an inorganic filler; a curing agent; and a curing accelerator.
