Unasco Pty Ltd traces its origin to the formation of W.S. Shamban (Australia) Pty
Ltd in 1962, a joint venture between the W.S. Shamban Co. of the U.S.A. and Australian
partners. By the end of the 1960s the W.S. Shamban Co. sold its share of the business
to its Australian partners and the company became known as Unasco Pty Ltd.
Under the leadership of H. William Bentley, Unasco Pty Ltd made a number of innovations
in the area of thread sealing tape. In the late 1970s Unasco was the first company
to systematically color-code thread sealing tapes for different applications. This
color-coding has become standard in many places in the world including the U.S.A.
& Canada. Bill Bentley also pioneered the concept of filled thread sealing tapes
for anti-seize applications.
Since 1962 Unasco has proudly been at the fore front of manufacturers of thread sealing
tape world wide. Unasco aims to provide top quality products at fair prices.
