“…Recently, an alternative pigment namely calcined kaolin was found to exhibit similar properties to titanium dioxide [42][43][44] such as brightness, opacity and they are less costly [45,46]. Kaolin is essentially used in paints to improve the brightness of colours, controls the texture for dispersant and coat ability, cost effective, signi cantly extending the product life, improves opacity, gloss, colour and viscosity.…”

“…Kaolin is essentially used in paints to improve the brightness of colours, controls the texture for dispersant and coat ability, cost effective, signi cantly extending the product life, improves opacity, gloss, colour and viscosity. Very good quality of crack resistant paint with high gloss and opacity are produced from calcined kaolin [42,47]. The particle size majorly determines qualities of opacity, gloss, colour and viscosity in paint.…”

No thanks to the injurious levels of lead in paints reported in the past. This study seeks to revisit the concentrations of lead in paints from different sectors, brand and types in the Nigerian markets. The study was investigated to check the marketed paints for improved and healthy formulation. The analysis showed Pb levels (µg/g in dry weight) in the samples across different manufacturers ranged from 2,220 − 91,500 in a cream (water-based) and black (oil-based) coloured decorative paints. The levels of Pb in oil-based paint ranged from 4,490 − 91,500 with mean of 38100 and 2,220 − 91,500 with mean of 21,800 in water-based paints. The Pb level in the paint samples is 50 times the 600 µg/g and 500 fold the 90 µg/g recommended by the US EPA and CPSC for paints. The main Principal Component Analysis accounted for upto 70% indicating that lead compounds, are majorly used as pigment to improve the quality of paints by paint manufacturers. Lead, has continuously been reported for its toxicity and no safe levels for children. This study is so revealing. Therefore, there is a major challenge to abate lead in all paint sectors by the government and this, should be done in good time.

“…There are numerous benefits of replacing chemical-based or TiO2-based pigments with renewable resources like kaolin. These include a major drop in the environmental impact of paints, a reduction in abrasion, improved mechanical qualities, and increased operational durability [16][17][18].…”

This research is focused on evaluation of kaolin (Calcined Aluminum Silicate) micro-based pigment or filler that can substitute titanium dioxide in waterborne paints. Calcined aluminum silicate has shown ability for partial replacement of titanium dioxide by fractionally and runnability. Titanium dioxide is very essential white pigment that has highest hiding power in waterborne coatings. But titanium dioxide is most expensive pigment. Our purpose was to find inexpensive pigment for replacement of titanium dioxide that does not affect properties of waterborne coatings but reduce cost of titanium dioxide in paint formulation. Fillers or calcined aluminum silicate has effect on properties of coatings like gloss, textures, viscosity, emulsion and tinting or coloring strength of paint. Our research main focus was that these properties of paint will not be affected by replacement of TiO2. To evaluate new pigment five samples are prepared in laboratory using high speed disperser. These samples were prepared at room temperature with same period of time in mixer. One sample is prepared as standard with no replacement of TiO2, other four sample were prepared with TiO2 replacement about 5%, 10%, 15% and 20% in coatings. Additives, binder and fillers were added according to paint basic formulation. Tests includes gloss, appearance, opacity, density, viscosity, smoothness, scrub resistance and whiteness or brightness. Results of these samples show that calcined aluminum silicate has potential to replace titanium dioxide in paint. The rheological, optical, mechanical and weathering properties were studied. Other properties like gloss, opacity, density, viscosity, brightness, scrub resistance, brushability, light fastness and reflectivity values were in range. In our study it is shown that titanium dioxide can be replaced from 5% to 20% in waterborne coatings without any effect on properties of paint. Replacement of titanium dioxide give better quality and economically favorable.
