Abstract
Polymer concrete compositions comprising a silane-modified polymer (SMP) composition which comprises a silylated polymer, an epoxy resin, e.g., an epoxy-terminated prepolymer, and a cure catalyst, e.g., tetraethyltetraamine, exhibit good adhesion to wet concrete.
Claims9
A SMP composition comprising (A) a SMP, (B) an epoxy-terminated prepolymer, and (C) a cure catalyst.
A polymer concrete comprising a silylated polymer composition comprising:
- A) A silylated polymer comprising at least one molecule of Structure 1:
- where A is either H or has the Structure (II):
- k is a number from 0 to 4;
- m and n are independently numbers from 0 to 3;
- x is a number from 5 to 150;
- y is a number from 4 to 20;
- RI, R2, R10, and R11 are independently straight chain or branched chain alkyl groups having from 1 to about 4 carbon atoms;
- each individual R,0 are the same or different and each individual R11 are the same or different;
- R3, R4, R5, R6, R8, and R9 are independently selected from H and straight chain or branched chain alkyl groups having from 1 to about 4 carbon atoms;
- R7 has from 2 to about 20 carbon atoms and is aliphatic, cycloaliphatic, bis-benzylic, or aromatic;
- and if k is 0, then n is 0 and R1 and R2 are coupled through a carbon-carbon bond;
- B) A polymer containing reactive epoxy functionality, and
- C) A cure catalyst.
