SAUKVILLE - A worker was injured Friday in an explosion at the Cook Composites & Polymers plant in Saukville.

The victim, a 57-year-old Grafton man, suffered severe burns.

According to Saukville Police, the man was mixing several ingredients and had just put them in a heated kettle which caused a "flash back," burning the employee. He was transported to Columbia St. Mary's Hospital in Mequon.

The company's Web site says, Cook Composites "is a world leader in the production and distribution of gel coats, unsaturated polyester resins, coatings resins and emulsions."

It is the world's leading producer of gel coats and also has the largest composites distribution network in North America.
