Research and Development

The research, development, and manufacturing of all API USA products are conducted in laboratories and facilities right here in the United States of America. Many of our products have been designed to meet the needs of individual customers. As a brand of The Stonhard Group, we have access to world-class laboratories and manufacturing facilities. This has driven the innovation, development, and quality improvements which have led to resin-based formulas that have chemical and physical advantages that are hard to find in other materials.
