Organic solvents are commonly used in 2-pack waterborne epoxy coatings such as high performance floor finishes. Generally, these solvents provide various benefits, such as facilitating proper film formation, making it easier to mix parts A & B together, and are also thought to extend the pot-life. However, due to new lower VOC limits on floor coatings enacted in the south coast region of California, the reduction or removal of organic solvents is desired. By using specific raw materials and formulation techniques, it is possible to formulate garage concrete floor topcoats with VOC contents below 50g/L, while maintaining good performance properties and ease of field applications by do-it-yourselfers (DIY) |
