Figure 1: Comparison of two silicone hybrid resins with a high-solids polyester resin.
Experience shows that, with conventional binder technology, it is not possible to formulate high-solids paints with fewer than 250 g/L VOC. Simply reducing the solvent content in existing medium-solids paints to meet legal requirements results in a highly viscous paint which cannot be applied. To reduce the non-volatile components (NVCs) requires major changes in the molecular structure of the binder.
Reduction in molecular weight, improved dilutability of the resin
