Definitions

  • polyisocyanates are understood to mean di- and higher-functional isocyanates, preferably di- and trifunctional, in particular difunctional. Examples include: tolylene diisocyanates, diphenylmethane diisocyanates, isophorone diisocyanate, xylylene diisocyanate, hexamethylene diisocyanate.
  • reaction products according to the invention can be used without the addition of copolymerizable monomers or solvents. However, since in many cases the products are viscous, it is advisable to mix them with copolymerizable monomers in order to obtain viscosities suitable for processing and / or to vary the properties of the curing products.
  • the coating agents can be applied to suitable substrates by means of methods customary in the paint industry, such as spraying, rolling, knife coating, printing, dipping, flooding, brushing, brushing.
  • the mixture is stirred at 60 ° C. under dry air until the NCO value is 0.1% by weight. A colorless and odorless, medium-viscosity resin is created.
  • a prepolymeric urethane acrylate according to Example 1 is produced, but with the change that instead of 6.1 g of thiodiglycol, 22.4 g of a polyester made from triethylene glycol and methylene bisthioglycolic acid (OH number: 250) are used.
  • 35 g of a bisepoxide based on hexahydrophthalic acid bisglycidyl ester (epoxy equivalent weight: 175) are reacted with 40 g undecane carboxylic acid at 90 ° C. to an acid number of 0.
  • the reaction product is then reacted with 34.8 g of tolylene diisocyanate and then with 23 g of hydroxyethyl acrylate.
  • the result is a resin with an NCO content of ⁇ 0.1% by weight.
  • a customary, red-colored primer consisting of a soft polyacrylate binder (approx. 25 Shore A), albumin and a medium-hard butadiene-acrylonitrile binder (approx. 40 Shore A) sprayed on, dried, ironed, embossed and then uniformly sprayed on the UV-light-curable mixture mentioned in Example 4 and diluted 1: 1 with ethyl acetate. After curing (polymerizing) using a Hanovia lamp, a glossy, rubbing and solvent-resistant finish was obtained.
