Which of the following is NOT a type of Cold Coating?

Polyurethane is not considered a type of cold coating. Cold coatings are typically liquid-applied materials that do not require heating for application and are commonly used because they can be applied in a variety of weather conditions.

Cutback coatings and emulsion coatings are examples of cold coatings; they are formulated to be applied at ambient temperatures without the need for heat. Cutback coatings often consist of asphalt combined with solvents, allowing for easy application and good adherence to surfaces. Emulsion coatings are made from asphalt dispersed in water, making them safe to handle and apply without fumes.

Silicone, while it can be applied at lower temperatures compared to hot-applied coatings, is also considered a cold coating due to its application characteristics and curing process that does not require heat.

In contrast, polyurethane coatings are typically part of a different category, known for their chemical resistance and durability, often requiring specific conditions for optimal application and curing, which sets them apart from traditional cold coatings.
