摘要:
The present invention provides a polyester (meth)acrylate resin composition that is excellent in terms of compatibility with dicyclopentenyloxyethyl (meth)acrylate (B) and that has a suitability for spraying that means the composition is suitable for use in a spraying method in the field of civil engineering and construction and the like, a coated structure produced by coating the same, and a method for constructing the same by using, as an acid component of the polyester structure of a polyester (meth)acrylate resin (A), an alicyclic dibasic acid (A1) and/or an aliphatic dibasic acid (A2) in an amount of 40% by mole or more.
摘要:
A primer composition used for applying a radical-curable resin-based waterproof material onto a concrete floor slab of an existing or newly established road bridge, is a troublesome application. For example, it is a problem in that a large machine is required for application thereof. The primer composition is a resin composition containing a urethane (meth)acrylate resin, (B) a polymerizable unsaturated monomer containing a hydroxyalkyl (meth)acrylate (B-1) and another polymerizable unsaturated monomer (B-2), (C) a curing accelerator, (D) a paraffin wax, and (E) a drying aid, in which the above components satisfy a specific molar ratio and specific mass ratios. The primer composition has a good crack-load-following capability, blistering resistance, adhesiveness, and bending resistance. Also provided is a waterproof floor slab structure using the primer composition and a method for waterproofing a floor slab.

摘要:
An object of the present invention is to provide an air-drying polyester (meth)acrylate resin composition in a curing system of a ketone peroxide curing agent and a cobalt-based curing accelerator, the resin composition being used as a topcoat in the field of civil engineering and construction, and having such good properties as, when coated or stacked, being capable of forming a cured coating film with no bubbles remaining therein due to non-bubbling properties of suppressing the generation of bubbles in the course of the curing reaction and being free from problems related to room-temperature curability such as a retarded gelation time, even after being stored for about one month; a structure coated with the resin composition; and a method for applying the resin composition.
