  • Patent number: 6333095
    Abstract: A flame-retardant adhesive film comprises an insulating substrate film, a flame-retardant interlayer provided on the insulating substrate film, and a flame-retardant adhesive layer provided on the flame-retardant interlayer. The flame-retardant interlayer has higher flame retardance than the flame-retardant adhesive layer. The flame-retardant adhesive layer contains a nitrogen-containing organic flame retardant, and the flame-retardant interlayer contains a non-halogen-based flame retardant with better flame retardance than the nitrogen-containing organic flame retardant.

  • Patent number: 6306317
    Abstract: A phosphate and ammonia free composition for treating an object (i.e., lumber, plywood and other wood products) is described. The treating solution may be applied to the object by dipping, soaking, brushing, spraying, etc., however, vacuum and/or pressure techniques may be used to impregnate the object according to the method of this invention, including both the empty-cell process and the full-cell process. The composition achieves fire retardant qualities without object degradation when the treated object is subjected to heat and humidity over time. The composition of this invention includes nitrogen in a predetermined ratio to boron.

  • Patent number: 6294006
    Abstract: An anticorrosive and antifouling additive for paints, which is effective to protect structures such as steel ships and pipes from rust, and prevent the adhesion of marine organisms and algae to the structures used in seawater without adversely affecting the marine environment, and a paint containing the same additive are provided. The additive comprises 70 to 94% by weight of at least one selected from the group consisting of bastnasite, monazite and Chinese complex mineral, 3% by weight or more of tourmaline, and 3% by weight or more of zircon, with respect to the total amount of the additive. The additive emits a required amount of negative ions to achieve the effect of preventing the adhesion of marine organisms and algae and prevents the occurrence of rust. In practical use, the additive can be added to a conventional paint in an amount of 8 to 15% with respect to paint weight.
