One example is protective coatings to shield materials in some way, making it resistant to water or UV-radiation. They can also lend it completely new functions, such as when an inert carrier material is coated with a catalytic substance.
The type of process used to apply a coating is usually determined by the nature of the material. Fine particles or granular bulk materials will need a different treatment than larger formed parts.
At IBU-tec, we can carry out coating of materials in combination with treatment of the material beforehand or afterwards in rotary kilns. Most often, the raw material is first coated in a mixer, and then the coating is cured or transformed by thermal treatment in a rotary kiln in order to create the desired characteristics of the product. A good example is the coating of proppants or gravel packs with phenolic resin, which is then hardened in the kiln.
If you need any help with projects that require a coating or impregnation step, please contact us! We will be happy to advise you.
