Epoxy Accelerators
 

Epoxy resins are made from tightly-linked, adhesive polymer structures and are often used in surface adhesives and coatings. They are capable of being cross-linked to form tough polymers that have a low shrinkage and strong adhesion, making them suited to applications that require toughness and resistance to chemical and environmental damage. The high strength and low shrinkage during cure, in addition to the almost unparalleled chemical and heat resistant properties, make epoxy resins ideal for use as potting agents, resin binders in fiberglass construction, electrical conductors, and for uses in various structural bonding applications. Like many chemical applications whose cost and efficiency depends on how fast a reaction occurs, the use of epoxy resins in structural applications depends largely on how fast it can cure. It is for this reason that epoxy accelerators are added to the resins to act as catalysts for the curing reaction.

There are a number of curing agents and epoxy accelerators available that are specifically designed for the various resin systems, such as the one-part and two-part systems. Epoxy accelerators and other cuing agents offer many advantages to epoxy resins. These include low volatility, low color, low viscosity, low exothermic heat of reaction, low affinity for carbon dioxide, high primary amine content, controlled reactivity, and miscibility with curing agents and solvents like water and flexible backbone. Resins with epoxy accelerators can be used in adhesives, protective and decorative coatings, potting and encapsulation, composites and laminates, and in the construction industry as sealants, decorative aggregates, and in wood consolidation and flooring. Some of the end-user benefits of epoxy accelerators include a high gloss in clear coatings, improved flexibility, toughness, thermal shock resistance, blush resistance and adhesion, decrease in shrinkage, faster setting times, moldability, good electrical properties, and good substrate wetability.

Resins with epoxy accelerators can be used in water-based systems due to the miscibility with other solvents. The miscibility with additional curing agents allows these resins to be used as reactive diluents that have a reduced working viscosity and have improved cured resin properties. To achieve all these benefits, it is important to use good quality epoxy accelerators that add to the benefits of epoxy resins.
