Partial selectivity has been obtained in commercially available black paint coatings by spray and dip techniques. It has been shown that the dip technique is superior to the conventional spray technique in giving low thickness, continuous and abrasion resistant coatings, having lower thermal emittance (ε) with comparable solar absorptance (α). Coatings without a primer underlayer have been found to be quite adherent. an ε value of 0.39 corresponding to an acceptable à value of 0.87 has been achieved in this technique by a suitable combination of thinner concentration and pulling rates.
