Abstract
The present invention is concerned with curable adhesive compositions for anchoring elements in a structural body that exhibit low temperature versus standard temperature degree of cures that are at least 50% or higher. The compositions include, in a first component, a reactive resin, an acetoacetoxy functional monomer and a silane monomer. By using phthalate-free constituents in the formulation, a further 10% increase in strength and durability of the resins at standard temperatures may be realized after curing at low temperatures
