  • Vacuum passivation furnace

    Vacuum passivation furnace

    Request for Price

    Passivation is a process that removes “free iron” contamination left behind on the surface of the componentsparts as a result of machining and fabricating processes. These contaminants are potential corrosion sites which, if not removed, result in premature corrosion and ultimately result in deterioration of the components.

    Application : In this process a chemical treatment accelerates the formation of an extremely thin, about 0.0000001 inch thick, oxide film on the surface of the clean part. This film prevents further corrosion of the surface.

  • UV-Transmitter

    UV-Transmitter

    Request for Price

    IR blocker coating is deposited on quartz windows and transmits the required UV energy from the light source while significantly suppressing the unwanted visible and infrared energy. It protects the heat sensitive materials from infrared radiation. Used in conjunction with our UV reflector coatings, this filter improves the efficiency of high power UV curing machines. It provides additional benefit by protecting the lamp and dichroic UV reflector in running the curing processes.

    uv curing

    Request for Price

    Conventional heat- and air-drying works by solvent evaporation. This process shrinks the initial application of coatings by more than 50% and creates environmental pollutants.Using light instead of heat, the UV curing process is based on a photochemical reaction. Liquid monomers and oligomers are mixed with a small percent of photoinitiators, and then exposed to UV energy. In a few seconds, the products - inks, coatings or adhesives instantly harden.
