High Resistance, High Durability & Excellent Adhesion Has Made Epoxy Valuable as Coatings

By Royceintl Subscribe to RSS | June 28th 2012 | Views:

Epoxy is a versatile substance, which finds myriad uses in furniture making and boat-building. In addition, it can be utilized in finishing, for dozens of specialty applications like inlay and as an adhesive. This material come in 2-parts, a hardener and a resin, and is available in numerous types, each with different properties. Additionally, there are slow-curing and fast-curing epoxies, and they can be thin or thick; it entirely depends on the application.

The applications of epoxy materials are widely extensive and include composite materials, coatings and adhesives like those making use of fiberglass and reinforcements. The chemistry of these resins and the range of commercially accessible variations facilitate cure polymers to be produced with an extremely wide range of properties. In general, these resins are popularly known for brilliant adhesion, their good-to-excellent mechanical properties, heat and chemical resistance and great electrical insulating properties.

Aerospace Applications:

In the aerospace sector, these adhesives are utilized as a structural matrix, which is then reinforced by fiber. Fiber reinforcements include boron, Kevlar, glass and carbon. These adhesives are utilized as structural glue.

Coatings and Paints:

Two-part epoxy based coatings were developed for hefty duty services on metal substrates and utilize less energy as compared to heat-cured powder coatings. These systems utilize a 4:1 by volume mixing ratio, and dry swiftly rendering a protective and hard coating with brilliant hardness. Their low volatility makes them gigantically useful for factory cast aluminum, cast steel, cast iron applications and alleviates flammability as well as exposure problems allied with solvent-borne coatings.

Industrial Composites & Tooling:

These adhesives are utilized in industrial tooling applications to produce master models, castings, laminates, fixtures, molds and other industrial production aids. This “plastic tooling” substitutes wood, metal and other conventional materials, and usually enhances the efficiency and lowers the lead-time for numerous industrial processes.

Electronics and Electrical Systems:

Epoxies boasts of immense importance in the electronic industry, and are employed in generators, switchgear, insulators, transformers, bushings and motors. These adhesives are brilliant electrical insulators and safeguard electrical components from moisture, short circuiting and dust. In electronic industry, these chemicals are the primary resins that are utilized in hybrid circuits and transistors, printed circuit boards and integrated circuits.

Marine and Consumer Applications:

These adhesives are sold in hardware shops, usually as a pack comprising of separate hardener and resin, which should be blended immediately before use. Furthermore, they are sold in boat stores as repair resins for marine applications as well. There are 2-key areas of marine use. Since it possesses better mechanical properties than polyester resins, these epoxies are utilized for commercial production of components, wherein high weight/ratio is entailed. The second area is their gap filling properties; solid strength and excellent adhesion to myriad materials including timber have created a boom in recreational building projects including boats and aircrafts.
