Abstract:
Effect of addition 0.5 and 1% of poly (vinyl chloride-co-vinyl acetate) (PVCV) as crosslinking agent to acrylic syrup on mechanical properties of primer was studied. Acrylic syrup made from a methyl methacrylate monomer solution of terpolymers. Terpolymers were used based on methyl methacrylate, 2-ethylhexyl acrylate and methacrylic acid. Mechanical properties including pot-life, tensile strength, elongation, water absorption, contact angle and bond strength were investigated. The results showed that the addition of PVCV to acrylic syrup improved the mechanical properties of primer due to the presence of carbon-chlorine bonds which produce the dispersion forces. However, as the concentration of PVCV increases, the mechanical properties of primer increases. The primer syrup containing 65% 2-ethylhexyl acrylate and 1.0% PVCV has good bonding strength with concrete substrate around 2.05 MPa.
