Abstract
Provided is a curing agent containing a diester compound represented by the following Formula (I): wherein in Formula (I), R1 and R2 each independently represent a hydrogen atom or a monovalent hydrocarbon group having 1 to 15 carbon atoms, or R1 and R2 are bonded together to form a divalent hydrocarbon group having 3 to 15 carbon atoms; and R3 and R4 each independently represent a monovalent organic group having 1 to 30 carbon atoms, or R3 and R4 are bonded together to form a divalent organic group having 3 to 30 carbon atoms.
Claims9
A curing agent comprising a diester compound represented by the following Formula (I):
- wherein in Formula (I), R1 and R2 each independently represent a hydrogen atom or a monovalent hydrocarbon group having 1 to 15 carbon atoms, or R1 and R2 are bonded together to form a divalent hydrocarbon group having 3 to 15 carbon atoms;
- and R3 and R4 each independently represent a monovalent organic group having 1 to 30 carbon atoms, or R3 and R4 are bonded together to form a divalent organic group having 3 to 30 carbon atoms.
A method for suppressing penetration of a deterioration factor into a cement-based structure by coating at least a portion of the surface of the cement-based structure with a surface protective agent containing a diester compound represented by the following Formula (I):
- wherein in Formula (I), R1 and R2 each independently represent a hydrogen atom or a monovalent hydrocarbon group having 1 to 15 carbon atoms, or R1 and R2 are bonded together to form a divalent hydrocarbon group having 3 to 15 carbon atoms;
- and R3 and R4 each independently represent a monovalent organic group having 1 to 30 carbon atoms, or R3 and R4 are bonded together to form a divalent organic group having 3 to 30 carbon atoms.
