Definitions

  • the invention relates to an anti-slip coating and the processing of synthetic silica in nano-particle form as an additive in a composition or mixture, for use as a slip-resistant coating or floor covering with anti-slip properties.

  • RIO means: normal friction coefficient
  • Rl 1 means: increased coefficient of friction
  • R12 means: high static friction value; Inclination angle> 27 ° - 35 °
  • Rl 3 means: very high friction coefficient; Inclination angle> 35 °
  • builders and architects are increasingly paying attention to the required slip resistance classes when selecting floor coverings. More problematic is the retrofitting of old systems in which not the flooring material can be replaced, but by a new coating of the floor covering the required Slip safety class must be adjusted.

  • Such coatings have slow curing properties of up to 12 hours at 20 ° C. for drying and 24 hours for accessibility. For full cure under standard atmospheric conditions, 5 to 7 days are required for such coatings.
  • the addition of accelerators can reduce the drying time by about 50% and make coatings passable in 4 to 6 hours.
  • a major disadvantage of this acceleration is the strong odor, which is particularly dangerous indoors, so that the use of these coatings is often rejected by the customer.
  • Epoxy-based compositions have in normal case short pot life of up to 30 minutes and at standard temperature a drying time of up to 12 hours. Accelerators can significantly shorten the drying time, but also reduce the pot life and lead to significant yellowing, with more or less strong yellowing. The odor development is weaker compared to acrylic-based compounds and the abrasion values are significantly better. A serious disadvantage for the processing are the short pot lives. In addition, due to yellowing, epoxy-based compositions are often rejected by the customer.
