Bill Bunnelle


Bill graduated from Century College in White Bear Lake, Minnesota with an Associate Degree in Chemistry.  In 1975, he joined the H.B. Fuller Company in St. Paul, Minnesota as a laboratory technician in the Hot Melt R&D Laboratory.  During the next 28 years Bill proved himself to be an exceptional product development chemist, and developed many of the first products for such applications as diaper construction and elastic attachment adhesives.

In 1990, Bill became H.B. Fuller’s first Hot Melt Research Fellow, the company’s highest technical rank, and in 2002 he received the company’s Annual Technical Achievement Award.   

Some of Bill’s career highlights include:
