Abstract
A sprayable polyurethane based reaction system for forming a protective coating in industrial containers includes a first component and a second component, each having a viscosity less than 1500 cP at 25° C. A difference between the viscosities of the first component and the second component within a temperature range of 60° C. and 80° C. is from −150 cP to 150 cP. The first component is a reaction product of a polyol component that includes a first butylene oxide propylene oxide copolymer polyol having a polyoxybutylene content of at least 50 wt % and an isocyanate component that includes at least one polyisocyanate. The second component has a second butylene oxide propylene oxide copolymer polyol having a polyoxybutylene content of at least 50 wt %. At least one selected from a group of the polyol component and the second component includes a primary hydroxyl containing polyol.
