Amercoat Canada, Headquartered in Oakville Ontario, is the licensed Canadian manufacturer of PPG / Amercoat Protective and Marine Coatings. Formed in 1993, in partnership with the Allcolour Paint Group of Oakville Ontario, Amercoat Canada assumed the business activities of Ameron Canada Inc., a wholly owned Ameron company which had distributed Ameron coatings in Canada since 1984.

The Amercoat Corporation was established in California in the 1950's and was eventually renamed Ameron Protective Coatings. In 1996, Ameron purchased the Devoe marine coatings business of Imperial Chemical Industries PLC. The acquisition made Ameron the largest supplier of high-performance marine and offshore coatings in North America and also greatly expanded the company's sales and service network and global presence in these markets. Early in 1997, Ameron also acquired the worldwide Valspar maintenance coatings business. Both these product lines are available in Canada through Amercoat Canada. PPG established a new business unit, PPG Amercoat Protective and Marine Coatings. In 2007 PPG acquired Sigma Coatings which is also being incorporated into the PPG PMC group worldwide.

Ameron high performance coatings are used throughout the world to protect steel and concrete in industries such as oil and gas production, refining, petrochemical processing, marine and offshore, power plants, pulp and paper plants, infrastructure maintenance, railroads, general manufacturing, and municipal water and wastewater treatment. Ameron high performance coatings safeguard structures such as the Hibernia platform and Terra Nova FPSO offshore oil installations in the Grand Banks Newfoundland, the historic Peace Bridge that spans the Niagara River between Buffalo, N.Y. , and Fort Erie, Ontario and the huge container port cranes at Robert Banks in the Port of Vancouver.

The majority of Amercoat coatings products are now "environmentally designed" with low-solvent, solvent-free and waterborne technologies that reduce the possibility of pollution and enhance workers' safety.

Amercoat coatings, since the 1950's have been industry-leading coatings technologies. These include:

• Dimetcote (1950), the first heavy-duty water based inorganic zinc silicate primer for steel;
• Amerlock (1981), the first full colour range high-solids, low-solvent, surface-tolerant (i.e., can be applied over intact rust and old paint) epoxy coating for steel and concrete;
• Amershield (1986), the first high-build, low-solvent polyurethane which offers far more resistance to impact and abrasion than conventional polyurethane's, and
• PSX 700 (1993), the first epoxy polysiloxane coating, a new technology that significantly enhances resistance to corrosion, heat, weathering and a wide range of chemicals.

Manufacturing of Amercoat coatings in Canada is carried out in the Group's 65,000 sq ft ISO 9001 certified plant in Oakville. Distribution of our coatings throughout Canada is available through office/warehouses from St. John's, Newfoundland to Victoria, BC in conjunction with General Paint of Vancouver, BC in Western Canada. Amercoat Canada is also the Canadian distributor for Vinyl Ester and Epoxy Novolac chemical resistant surfacers, linings, and floor coatings manufactured by Polyspec Corporation. In addition Amercoat Canada's associate company, Nukote Canada Inc, is the Canadian Distributor of Nukote Polyurea coatings.
