Abstract
A composition and method for consolidating aggregate material is disclosed. The method includes introducing a reaction composition into the aggregate material and allowing it to reach on form a polymer which binds the aggregate together. The composition includes polyol, isocyanate, and ester.
Claims21
A method for consolidating aggregate material comprising:
- introducing a reaction composition into aggregate material;
- and
- allowing the composition to react and form a polymer;
- wherein the reaction composition comprises:
- polymeric MDI, and a B-Side component comprising between about 35 weight % to about 45 weight % of an amine based polyether polyol, about 15 weight % to about 35 weight % polyglycol, and about 20 weight % to about 45 weight % 2,2,4-trimethyl-1,2, pentanediol diisobutyrate.
