Curing Agents & Dilutents
Curing agents (cross-linking agents) are substances or mixtures of substances added to a polymer composition to promote or control the curing reaction. Basic materials such as amines and amides are used for epoxy reactions.
An agent which influences the reaction rate but does not enter into the reaction is known as a catalytic hardener, catalyst or accelerator.
Diluents are divided into two categories: non-reactive (inert) and reactive. Diluents are used to reduce the thickness (viscosity) or consistency of another substance.
List of Agents & Dilutents
Formulated Polyamines offered include AEP replacement, underwater cure, fast set, and high chemical resistance (hcr), and flexible/toughener additives. Other base chemistries include aliphatic amines, aromatic amines, cycloaliphatic amines, polyetheramines, modified aliphatic amines, modified cycloaliphatic amines, mannich bases, phenalkamines, amidoamines, polyamides, and mercaptans.
Our offering of catalyst (or accelerators) range from tertiary amine complexes to other metal and non-metal chemistries. These are effective initiators for epoxy resins cured with polyamines, polyamides, and amidoamines.
Reactive diluents are epoxy functional and include mono-functional aliphatic, di-functional aliphatic, tri-functional aliphatic, mono-functional aromatic, di-functional aromatic, and cycloaliphatic di-functional.
For non-reactive diluents, please refer to Bech Chem’s offering of benzyl alcohol, toluene sulfonamide, liquid hydrocarbon resin, and filtered coal tar.
