A two-package solventless rust preventive material comprises (A) a sprayable component essentially containing a liquid epoxy resin and a liquid polycarboxylic acid anhydride and (B) a sprayable component essentially containing a liquid primary or secondary amino compound and a curing accelerator, at least one of said components (A) and (B) essentially comprising a non-reactive epoxy resin diluent having a molecular weight of 300 to 4,000 and an electrically conductive powder.

Two-package solventless rust preventive material

A novel unsaturated polyester resin composition comprising an unsaturated alkyd and a crosslinkable vinyl monomer, said unsaturated alkyd being a modified unsaturated alkyd obtained by reacting a polybasic acid with a polyhydric alcohol in the presence of a cyclopentadiene-type oil having a viscosity at 25.degree. C. of 50 to 50,000.

Unsaturated polyester resin composition

Adhesive compositions

Hydrocarbon resins having a softening point of 60.degree.-140.degree.C and a Gardner color of 6 or less and having excellent cohesive strength and thermal stability prepared by copolymerizing 1,3-pentadiene and cyclopentene, together with, if desired, 1,3-butadiene or isobutene and small amounts of incidental other olefins in the presence of aluminum chloride.
