Dexter and Sons, the company grew from a family-owned saw and grist mill and evolved into a multi-national producer of long fiber papers and chemical laminates.

In its 233 years of operation, the company grew from manufacturing tissues, toilet paper, and tea bags to marketing more specialized products like medical garments and industrial finishes.

Faced with a proposed buyout by International Specialty Products Incorporated in 2000, the Dexter Corporation separated its three divisions and sold them off to avoid a hostile takeover.

The Specialty Polymers division was sold in part to AkzoNobel, and the remaining businesses merged with Loctite Corporation.

The third division, Dexter Nonwoven Materials, located on the company's original site in Windsor Locks, was sold to the Finnish Ahlstrom Paper Group.

The physical plant continues to operate, with offices located nearby at 2 Elm Street.

In 2011, the Home and Personal Nonwovens division of Ahlstrom Windsor Locks was sold to Suominen Corporation, also headquartered in Finland.
