Coatings update: new raw materials

If the paint chemist is to meet the challenges of ecology, toxicity, and government regulations generally, he must rely on two things. One of these is formulating skill, the other, new raw materials. In fact, however, there have been very few truly new raw materials in the past decade. Most of the advances have involved variations of known products and these variations have related to the needs of the paint chemist. For example there has been a strong desire to convert materials which are normally solvent‐based to forms useful in water‐borne compositions.
