Provided are a curable composition which can easily reinforce shaped objects and can provide shaped objects with good color developability and excellent texture, and a method for reinforcing shaped objects using the same. The curable composition comprises a 2-cyanoacrylic acid ester and a surface conditioner, the content of the surface conditioner being 0.001-10 parts by mass relative to 100 parts by mass of the 2-cyanoacrylic acid ester, and the surface tension of the composition being 28 mN/m or less at 25°C. Preferred surface conditioners are silicone-based and fluorinated surface conditioners.
摘要:
The present invention relates to a cyanacrylate adhesive, comprising at least a 2-cyanacrylate and polyacrylnitrile. The invention also relates to the use of such adhesive mixtures as adhesive having improved water resistance and/or for the gap-filling bonding of substrates.
摘要:
Disclosed are methods and compositions for closing and sealing a wound, laceration, incision, or other percutaneous opening using an adhesive. In one preferred embodiment, the sides of the percutaneous opening are brought together in apposition and the adhesive is applied topically over the apposed opening and the skin adjacent thereto. Adhesives used in the methods of the preferred embodiments exhibit sufficient viscosity to substantially prevent flow of the adhesive into the percutaneous opening. Adhesives may also be used in surgical applications, as a covering for a trauma to the outer surface of the skin, or as a secondary means of closure in combination with other means of closure, including staples and sutures. In a preferred embodiment, the adhesive is a adhesive comprising cyanoacrylate monomer, cyanoacrylate polymer, and a plasticizer.
摘要:
This invention relates to cyanoacrylate compositions that include, in addition to the cyanoacrylate component, a compound embraced by structure A: where D is independently a member selected from O or S, and A is independently a member selected from hydrogen, linear, branched or cyclic alkyl groups having from 1 to about 20 carbon atoms, alkenyl groups having from 2 to about 20 carbon atoms, alkynyl groups having from 2 to about 20 carbon atoms, and aryl groups having from 6 to about 20 carbon atoms, with or without interruption or substitution by a member selected from halogen, silicon, hydroxy, ester, and sulfate, provided that at least one A is not H and that at least one A has at least one carboxyl group attached thereto.
