What Does Aliphatic Acrylic Urethane Coating Mean?
An aliphatic acrylic urethane coating is a chemical compound used to protect metallic surfaces from contact with external corrosion causing agents. It is composed of several chains of urethane, which is a synthetic crystalline substance with high toughness and flexibility.
Corrosionpedia Explains Aliphatic Acrylic Urethane Coating
Aliphatic acrylic urethane coatings are primarily composed of polyurethane compounds. The molecular forces within polyurethane are spring-based with strong intermolecular attractions, which give polyurethane compounds their unique physical characteristics of being both flexible and tough.
Coatings that are created from polyurethane compounds, such as aliphatic acrylic urethane, typically have high tensile strengths and elongations that are also maintained at very low temperatures. This trait makes aliphatic acrylic urethane coatings suitable for outdoor and industrial usage. However, the use of acrylic urethane coatings in high temperature environments above 100°C (212°F) is best implemented with the complimentary use of an epoxy coating for support.
