摘要:
A polyurethane-based resin useful, for example, to repair a surface of a rubber-based component includes a pre-polymer component that is combined with a polyol component. The pre-polymer component includes polyisocyanate, hydroxyl terminated poly-butadiene and ether diol. The polyol component include aliphatic oil, hydroxyl terminated poly-butadiene and aromatic diamine. The polyol component and the pre-polymer component are combined for a selected amount of time to react together and form the polyurethane based resin. The resin may be applied to the surface of a rubber-based component.
