We at Fuji Chemical specialize in both fine chemical technology pertaining to adhesives, coating, potting and printing and resin processing technology for precision extrusion molding of engineering plastics. We aim to contribute to society by assisting our customers with industrial technology and our engineering service of printed circuit board assembly.

The mounting density of PCBs can be called the heart of electronic appliances and equipment. This mounting density has increasingly become higher to result in the narrowing of space between leads. Furthermore, usage requires PCBs products to stand against a variety of application environments. Some problem causing factors at issue lately are moisture, condensation, oil, detergent, impurities, cohesion of mold, dead insects dust and lead breaks due to vibration have not been addressed adequately at this time. "Seal-glo insulating moistureproof coatings” dries into a thin film at room temperature, while maintaining excellent anti-moisture and insulating properties. This coating will stabilize components as it seals out moisture ( known as conformal coating applied for several types of circuit boards) and numerous types of electronic parts. We are confident that “Seal-glo　insulating moisture-proof coatings” will surely enhance the quality and reliability of the electronic equipment that it is applied to.

■Conformal coating for PCBs of home appliances, industrial electronic devices and automobile in order to moisture proof, dust prevention, and antifouling.

■Moisture proof and Insulating seal to the terminal area of IC and LSI

■Airtight seal for moisture proof and insulating to the coil , trance, relay and hybrid IC.
