  • Binders 'B' & 'D' gave a smoother film.
  • Binder D was better than binder C.
  • Paint powder samples 'G' (without water conditioning component) and ⁇ ' (with water conditioning component) were used. Each sample (100 g) was mixed with 150 ml of mixing water over a 5 minute period using an electric pedestal mixer with a 20 mm horizontal disc blade.
  • Two pH meters were used to take readings: A RaHs PH-009 and a Techpel PH-703. Both meters were calibrated with a pH 7.00 buffer solution. After the initial mixing period of 5 minutes, pH readings were taken on each sample at intervals of 5, 15, 30 and 60 minutes.
  • the addition of the water conditioning component has a significant effect in inhibiting gelling and thereby extending the usable pot life of the paint (Table 1).
  • the water conditioning component also has a 'buffering' effect which reduces the effect of varying pH levels of the tap water used for mixing the paint product.
  • a 'buffering' effect which reduces the effect of varying pH levels of the tap water used for mixing the paint product.
  • the use of the water conditioning component means the pH level of the resulting paint is contained within boundaries which are known to inhibit the growth of mould and fungus.
  • Table 1 Effect of water conditioning component on inhibition of gelling of paint at various mixing water pH levels.
  • Figure 5 is a photographic image of paint sample E of reflected light.
  • Figure 6 is a photographic image of paint sample H of reflected light.
  • Figure 7 is a photographic image of paint sample E of reflected light.
  • Figure 8 is a photographic image of paint sample H of reflected light.
  • Binder sample D yields very good adhesion and water conditioning/buffering properties. Paint sample H has very good paint properties.
  • Figures 5 to 8 illustrate the beneficial results from the present invention.
  • the shearing process yields a significant reduction in particle agglomeration.
