Permathane Aliphatic II incorporates a 70620-CA aromatic urethane base coat with a 7490-CA aliphatic urethane topcoat. The 20-year warranty system carries a Class 4 Very Severe Hail rating. It is ideal for institutional, commercial, industrial, and high-rise/multi-family residential applications. Recommended SPF density is 2.7–3.2 pounds.

Innovacoatings -CA urethane roof coatings form a seamless membrane for superior durability, flexibility, color retention and long-term protection. They comply with South Coast AQMD VOC regulations. They are typically rolled, but can also be sprayed (contact Innovacoatings for information on spray equipment). Our 7490-CA aliphatic topcoat has high UV resistance, and is less likely to chalk than an aromatic coating. It and our 70620-CA base coat also have high tensile strength and chemical resistance, which prevents failure due to expansion and contraction of the system, and failures around critical areas like penetrations and flashing.
