Our company was founded in 1983, formerly named Zhuzhou Welfare Petrochemical Factory which served as a profit earning subsidiary of local civil administration to fuel government expense on welfare issues.

Now we are a full enterprised company. We have 180 employees, including more than 70 technical persons. We mainly offer crystal violet lactone (CVL) and naphthenate/ethylhexanoate based coating dryers. The annual production of CVL is 80 tonnes.

We focus on research and development. We are in close collaboration with some academic research institutes to bring out new products and solutions needed by customers.
