Abstract
The disclosure involves an improved asphalt roof-coating composition which includes asphalt, clay, and a novel ether amine-acid-complex surfactant. The surfactant comprises an alkyloxyalkylamine, preferably having an alkyl chain with from 8 to 20 carbon atoms and an acid present in an amount in excess of the amount required to neutralize the amine. The composition is less expensive than prior art formulations and has improved viscosity and gel stability.
