A vehicle bond filler formulation is provided that includes a part A having curable resin and a monomer reactive diluent. A part B storage-separate, cure initiator package contains a free-radical cure initiator. At least one color changing dye adapted to change color upon mixing the part A and the part B and within ±5 minutes of cure of the curable resin to a sandable condition is present in either the part A or a separate part C, a guide coat colorant, or a combination thereof. A process of for repairing a vehicle body is also provided that includes mixing a part A containing the at least one color changing dye with the part B to form an internal guide coat mixture applied to a substrate of the vehicle body in need of repair. The mixture cures causing the color changing dye to the terminal change color within ±5 minutes of cure of the curable resin to a sandable condition.

A method for rapidly repairing a road surface includes: forming a base layer reinforcing material by low-shrinkage unsaturated polyester resin, diluent, expansion agent, accelerator, and polymerization inhibitor, adding a curing agent and pouring into a base layer at a damaged part of the road surface until infiltration is stopped; laying chopped basalt fiber, forming a surface layer repair material by acrylate monomer, acrylic resin polymer, silane coupling agent, calcium carbonate powder, talc powder, quartz sand, metal hydroxide flame retardant and accelerator, polymerization inhibitor and short cut basalt fiber; adding curing agent to fill the road surface and solidifying. The repairing method can not only play a reinforcing effect on the road base, but also repair the surface layer on the damaged parts such as cracks on road surface, so as to realize the dual functions of the base layer reinforcement and the surface layer repair.

A radical-polymerizable resin composition comprising one or more metal-containing compounds (A) selected from a metal soap (A1) and a β-diketone skeleton-containing metal complex (A2); one or more thiol compounds (B) selected from a secondary thiol compound (B1) and a tertiary thiol compound (B2); and a radical-polymerizable compound (C) can stably cure under a dry condition, in water and in seawater and further on a wet substrate. The radical-polymerizable resin composition is useful as a repairing material for inorganic structure, a radical-polymerizable coating composition, a concrete spall preventing curable material, a reinforcing fiber-containing composite material, etc.

There is described an acrylic polyester resin, obtainable by grafting an acrylic polymer with a polyester material. The polyester material is obtainable by polymerizing (i) a polyacid component, with (ii) a polyol component. At least one of the polyacid component and/or the polyol component comprises a monomer having an aliphatic group containing at least 15 carbon atoms.
