A manufacturer of mold-making and casting materials that has been successfully operating in the Lehigh Valley for 35 years is now expanding.

Polytek Development Corp., which has been headquartered in Williams Township since 1984, is a leading manufacturer of specialty polymers used primarily in mold making and casting applications in industrial, construction, entertainment, arts and crafts, and technology sectors.

Polytek announced this month that it has acquired Stone Coat Countertops, an Oregon-based supplier of high-quality epoxy coating systems, casting systems, and related accessories.

“The acquisition of Stone Coat has completed the assembly of our ‘dream team’ in this marketplace and we are excited to get out on the court together,” said Jonathan Kane, CEO of Polytek.

Focused on education and technical support, Stone Coat uses web-based channels and in-person demonstrations to teach artists, designers, woodworkers, and the do-it-yourself community how to create high-end, decorative surfaces and décor.

Stone Coat was established in 2014, and three years later the owners Mike and Kathryn Quist launched the YouTube channel Stone Coat Countertops, sharing educational videos about how to create unique surfaces with epoxy-based products. They quickly developed a loyal following of do-it-yourselfers, contractors, woodworkers, artists, and hobbyists.

“We are excited to work with a company whose values mirror our own and we look forward to collaboration and future growth,” said Mike Quist, owner of Stone Coat, which will continue to do business under its existing name.

High-performance manufacturing has been identified as one of the four optimal target industries for the Lehigh Valley based on the site-specific characteristics of the regional economy. The others are food and beverage processing, high value business services, and life science research & manufacturing.

Manufacturing makes up $7.4 billion – or 18.4 percent – of Lehigh Valley’s overall $40.1 billion gross domestic product. The region’s thriving manufacturing sector was recently the subject of a detailed article in Forbes magazine.

The acquisition of Stone Coat is the second acquisition announced by Polytek in the last three months.

The company announced in June that it had acquired the Florida-based Pro Marine Supplies, high-quality epoxy coating resins for a variety of professional and hobbyist applications, including arts, crafts, boat building, restoration and repair.

“We are excited to join Polytek and take our company to the next level,” Matt Bonwill, owner of Pro Marine, said at the time. Pro Marine will also continue to do business under its existing name.

Stone Coat and Pro Marine further extend the national presence of Polytek, which also has existing operations in Pomona, Calif., and Kalamazoo, Mich.

The specialty polymers manufactured by Polytek include polyurethane elastomers and casting resins, silicone, latex, plastisol, thermoplastic elastomers, and epoxies, according to the company.

 Other Polytek brands include brands include California Medical Innovations, Raw Material Suppliers, Alumilite, BCC Products, Environmental Technology, Inc., and Pro Marine Supplies.
