Wits for Win

"Stability is the Core, Technology is the Future". WINSTAR CHEMICALS is dedicated to providing quality chemical products for the industries and contributing to the society through technology — Mr Spande Chang, Executive Director of Winstar Chemicals Company Limited.

Company Profile

Established in 1985, WINSTAR CHEMICALS supplies professional chemical products to international brands from different countries, including those engaged in fashion, mobile phones, auto parts and telecommunications. More recently, its business has been further extended to consumer market with the launch of "AQULLUM" nano disinfection products; and a boutique for the sub-brand "AYYYA" has been opened at the newly-revitalised Central Market. Headquartered in Hong Kong, WINSTAR has branches and technical centres in Mainland China, Japan, Korea and Indonesia; and it possesses 29 invention and utility patents in Mainland China and over 20 product trademarks registered around the world.

Track of Glory

WINSTAR offers a wide range of products to serve various industries according to different standards, with customisation to meet customers' special requirements. WINSTAR places much importance on R&D. As early as 2003, it had brought into its R&D team talents graduated from reputable tertiary institutions in the Mainland and overseas. Many of its self-developed technologies have been successfully commercialised, including the recent ones that are applied to 5G products like wafers and transmitters.

Over the years, WINSTAR has launched a host of green products, in an attempt to foster sustainable development of the industries and promote environmental protection. For instance, its "ZICOLLUM", an environmentally friendly chromium-free zinc and aluminium coating, has been widely used in different industries. By virtue of continuous efforts, the Group was recognised as an "Environmental Green Credit Enterprise in the Yangtze River Delta" and "High Technology Enterprise" by the Shanghai Municipal People's Government.

WINSTAR recently launched the nano disinfection series "AUTOLLUM"(nano protective coating) and "AQULLUM"(nano disinfection product). It also gave special offers to social enterprises and provided training on the application techniques to car beauty and cleaning service industries, carrying out its mission of "Contributing to the Society through Technology".
