  • Patent number: 5403117
    Abstract: The present invention provides pavement and a paving material in which a large quantity of aggregates are bound with one another by a hot melt of thermoplastic resin powder, and also provides producing methods of such pavement and such paving material. The thermoplastic resin powder is neither limited in pot life, nor influenced by working conditions and weather conditions at the time when pavement is laid at a job site. Accordingly, uniform strength can be given to the resulting pavement or paving material. Further, the resulting pavement or paving material is excellent in weather resistance, elasticity and flexibility. Thus, the pavement of the present invention can be suitably used as pavement at play ground, parks, roads and the like. It is also easy to amend pavement, as necessary, after laid. The pavement producing method of the present invention can readily and efficiently produce the pavement.

  • Patent number: 5216093
    Abstract: The present invention discloses a low-temperature curing epoxy resin composition including: an epoxy resin main agent to which unsaturated acid ester of polyhydric alcohol is added and which contains epoxy resin having urethane bonds in the molecules thereof; and a curing agent containing an alicyclic amine compound. This epoxy resin composition may be rapidly cured even at a low temperature and presents a good work efficiency. This epoxy resin composition may be prepared as a cured body excellent in resistance to hot water, mechanical strength, impact resistance and the like.

  • Patent number: 5098973
    Abstract: The invention relates to a hardening resin composition including a monomer represented by the formulas (1) or (2), a monomer represented by the formula (3), and epoxyacrylate or epoxymethacrylate. This composition is easily hardened at low temperature, weak in odor, small in shrinkage in hardening, excellent during durability against water and hot water, and thus suitable as the flooring material for a food processing factory, refrigerated warehouse, and cold storage. ##STR1## where R.sup.1 to R.sup.6, p and r are as defined.
