Repellent (Encapsulation Coating)

Encapsulation coatings act as repellants in certain conditions and environments, and they provide important protection from exterior elements. Several industries, from food to chemical engineering, use encapsulation to repel undesirable factors such as moisture and oxidization. Using encapsulation coatings as repellents can make products resistant to extreme temperatures, abrasion, humidity, mold, and water . Using an encapsulation coating such as an epoxy adhesive can provide excellent protection in a variety of environments and circumstances.

There are hundreds of different types of encapsulations and just as many combinations of ingredients to create a repellent. For example, repellents used on woods, may consist of chromated arsenicals, creosote, and pentachlorophenol (PCP). Newer wood preservatives may have ingredients like propiconazole (a fungicide), acid copper chromate, and alkaline copper quaternary (an insecticide). Encapsulation options for metal and cement surfaces will typically come in the form of water-based acrylic coatings that prevent corrosion. Hydrophobic repellents will protect surfaces and products from water, moisture, debris, and abrasions. Hydrophobic coatings are important for protecting wood, electronic devices, and other products from water damage.
