Moisture cure coatings are predominantly made of which substance?

Moisture cure coatings are predominantly based on silicones due to their unique curing process that involves the presence of moisture in the air. These coatings utilize the moisture in the atmosphere to initiate a chemical reaction, leading to a durable, water-resistant finish. Silicones have excellent weather resistance and flexibility, making them ideal for roofing applications where exposure to environmental elements is a concern.

This functionality of silicones allows them to form a strong bond and maintain performance over a range of temperatures, which is crucial in the context of built-up roofing systems. Their properties improve not only water resistance but also UV protection, contributing to the overall longevity of roofing materials.
