What is left behind when the solvent in Cutback Coating evaporates?

• A. Water
• B. Asphalt
• C. Residual Solvent
• D. Coating Additives

Answer: (B)

When the solvent in Cutback Coating evaporates, what remains is asphalt. Cutback coatings are essentially asphalt that has been diluted with a solvent to achieve a desired workability. The solvent makes it easier to apply the asphalt, but it is not a component of the final product. Once the coating is applied, the solvent eventually evaporates, leaving behind the asphalt itself, which provides the protective and waterproofing properties necessary for roofing applications. This characteristic is crucial for the durability and effectiveness of the roofing system. The asphalt that is left behind solidifies, forming a robust layer that contributes to the integrity and longevity of the built-up roofing system.
