Are all sol-gel coatings the same?

No, they are not - just as not all conventional PTFE coatings are the same.

There are, in fact, many differences. Sol-gel systems are typically multipack systems. Each coating can have 2 or more packs to be mixed to achieve the final coating. So, for example, a one-coat sol-gel coating will have 2 or more packs to mix to achieve that coating. For a two-coat, each layer of the coating has multiple packs to mix, separately for each layer, and then applied as directed by the manufacturer. The number of packs per layer is determined by the coating manufacturer and varies from product to product. Also, some require a full 24 hours of mixing, while others as little as 3 hours.

Some of the newer Sol-Gels have more than twice the release of other coatings.

A few form tighter, more cohesive coatings, which improve their stain resistance. These few also provide greater eye-catching gloss at point-of-sale for the same reason. There is even one brand of sol-gel “ceramic” coatings that has been fully checked for regulatory compliance, supported by a legal letter verifying that it is compliant with the EU and US regulations for food contact.

It’s important to talk with your supplier to make sure you get the Sol-Gel coating that is precisely what you need, because they are not all the same.
