As the former president of Poly-Granite International in Wilmington, California, Gerald Thermos oversaw the manufacture and sale of various polyurea coatings. Gerald Thermos marketed these products to a diverse client base of construction professionals and companies.
A chemical created when a polyamine compound reacts with a diisocyanate, polyurea is a pure compound made without a catalyst. As such, it is not to be confused with polyurethane, which includes a third component that shortens the compound's reaction time. Pure polyurea, which already offers a fast reaction time that allows complete treatment in as little as one hour, is solvent free and provides a far higher ultraviolet stability compared to polyurethane, particularly when prepared using aliphatic diisocyanates.
Polyurea is seamless and applicable at any thickness. It bonds securely to carefully prepared, humidity-free substrates but can also bond acceptably at mild humidity levels. As such, it stands out as a particularly useful compound for waterproofing and atmospheric resistance applications, as well as for structural strengthening and protection against corrosion.
