About Company

Epichem's original product offering was primarily a line of ultra- high-purity metalorganic chemicals. Thanks to proprietary adduct purification techniques, our facilities yield volatile compounds of Al, Ga, In, As, P, Zn, Fe, Mg, Sb, N, Te and Cd with purities unmatched in the industry. The metalorganics are used in the growth of thin films of compound semiconductors such as gallium arsenide and indium phosphide. A wide range of electronic and optoelectronic devices are made from these materials including light emitting diodes (LEDs), lasers, detectors and solar cells. We also manufacture chemicals used to grow thin films of diamond and silicon carbide, high temperature superconductors and optomagnetic materials.

We have since added dedicated facilities for the production of the gases, boron trichloride and silane. These are used in the silicon industry, for the production of semiconductor devices. Silane is also used to produce thin glass coatings, e.g., for double and triple glazing. Boron trichloride can also be used in the pharmaceutical industry.

As a result of the Inorgtech acquisition, Epichem oxides and nitrides now offers metal alkoxide, alkylamide and beta-diketonate precursors for advanced materials technology. These products are used in a wide range of applications such as ferroelectric, ferrite, superconducting and piezoelectric thin films, barrier films in VLSI technology and antireflection coatings. Application techniques include metalorganic chemical vapour deposition (MOCVD), atomic layer deposition process (ALD), sol-gel, spin-coating, dip-coating, spray coating and vapour infiltration, depending on the desired material property.

Since the re-organization of the Epichem Group, the new Epichem Surface Coatings group has emerged. This sector produces chemicals for application to various building surfaces to protect from weathering, frost/thaw damage and graffiti. "Dynasylan BSM" is a water repellent product which will offer the ideal protection when applied to surfaces such as brick, mortar, concrete, etc. and act as a protective coating so that damaging weather conditions do not permanently destroy the building surface. "Protectosil Antigraffiti" treated surfaces are so repellent to coatings and paints, that they act as a deterrent to further graffiti "tagging", and really speed up the cleaning process.
