History

Mar. 1962 Sony Chemicals Corporation Established.

Sony Corporation put the Japan's first transistor radio TR-55 on the market in 1955, which achieved significant downsizing with the use of transistors in place of existing vacuum tubes. The company also succeeded in developing a copper foil with adhesive for printed circuit board (PCB) for transistor radios.In anticipation of the growing demand for transistor radios, Sony Chemicals Corporation was founded as a wholly-owned subsidiary of Sony Corporation for manufacturing and sales of copper foil products for circuits and industrial adhesive products, and encouraged domestic production.

Mar. 1963 Broke into the liquid adhesive domain to build up a new core business.

Sony Chemicals Corporation started production of Z782, a liquid adhesive for polyvinyl chloride (PVC) steel sheets with the opening of Haneda Plant. The company released Bondmaster "Tuff" for general-purpose adhesive for home use followed by a series of products including "Clear," "Epoxy" and "Vinyl." For industrial adhesives, as the certification of UL (Underwriters Laboratory) became mandatory for fixing of electronic parts in electrical appliances, chloroprene-rubber base flame retardant adhesive SC12N went on sale for fixing of electronic parts, so the company expanded the business in both domains, industrial use and home use. The next year the company also pushed into the industry of sealing materials for building materials.

Apr. 1964 The Primaster production line for printed circuits at the Haneda Plant was completed.

Production of the long-awaited copper foil with adhesive made in Japan started.

Apr. 1965 Expanded the application of bonding technologies to double coated tapes.

Sony Chemicals Corporation also moved into the double coated tapes industry. Following the introduction of home-use "Tuck Master," the industrial-use "Tuck Master" was also launched in 1967. Particularly the model #1477J introduced on the market in 1968 earned an excellent reputation, so it evolved into the later T4000 Series, which won a position as a standard option of high-performance double coated tapes.
