发明名称 FOAMABLE COMPOSITION EXHIBITING INSTANT THIXOTROPIC GELLING.
摘要 The invention relates to a foamable composition comprising at least two parts. The first part comprises a polyol, a thixotropic gelling agent, a blowing agent, a urethane reaction catalyst and a isocyanurate reaction catalyst. The second part comprises at least one isocyanate. A foam mass can be prepared by combining the first part polyol component with the second part isocyanate component. The composition is foamable under water and exhibits, upon foaming under water, substantially the same wet foam density and dry foam density. The invention also relates to a method of repairing or reinforcing structural members having defects such as spike holes left after spike removal from railroad ties during road bed maintenance or repair by means of the foamable composition.
