New resin technology for semi-matte and dull-matte powder coatings—part 2
Commercialized resin technology has been developed that provides a new route to manufacture matte powder coatings offering advantages in processing and gloss consistency. This patent-pending technology provides a new solution to obtain 60° gloss results in the semi-matte and near-dull-matte ranges for both standard and super-durable powder coatings. The new resin binder systems are combined with the powder coating ingredients in a single extrusion versus the typical use of either matting agents or dry-blend technology using previously manufactured powders of differing reactivity. This two-part article summarizes results confirming the reliability and attractiveness of the matte powder finishes that may be achieved through the use of this new technology. Part 1 was published in the September issue.
In part 1 of this article, the introduction of an advantageous new technology that provides reproducible semi-matte and dull-matte standard or super-durable powder coatings was introduced. In part 2 here, the performance attributes of the new one-shot matte technology are examined.
