| 摘要 |
This application concerns compositions comprising a mixture of air-drying dicyclopentenyl acrylate or methacrylate binder and a granular or particulate aggregate material, which may comprise a hydraulic cement, and is adapted to be formed by casting, extruding, or molding in any fashion into any desired shape and air-drying and resulting shaped article, thereby producing an integral, solid article of unitary mass and structure. The dicyclopentenyl (meth)acrylate may be used as an impregnant, polymerizable in situ, for already formed articles of porous nature, e.g., concrete, wood, pressed boards, and powdered pressed metal, such as aluminum, iron, steel, etc., to reduce the permeability at their surfaces and provides hard, continuous, hydrophobic, wear-resistant, and weather-resistant surfaces thereon.
