Study on Vinyl Ester Based Structural Anchor Adhesive for Fast, Low Temperature Cures

Abstract

An high performance two-component structural anchor adhesive based on vinyl ester resin is synthesized by adding the toughener to improve the material brittleness and bringing in chemical heat source to reduce the affection of the environment on chemical reaction and it can be cured in the damp or in the environment with water by adding the water-absorbable filler.Compound stabilizer consisted of inhibitor and oxalic acid improve the stability of the pro-accelerated vinyl ester resin.The adhesive exhibites high-early-strength developing, excellent bong strength with “can’t dry”substrate and can cure rapid in lower temperature.it allows construction crews to install threaded rod or rebar in concrete that is too damp or soaked to bond with other adhesives.
