摘要： 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 ºC. A difference between the viscosities of the first component and the second component within a temperature range of 60 ºC and 80ºC 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.
