The optical properties of coatings pigmented with different black colorants were systematically investigated and their surface temperatures and cooling energy savings were estimated. The black coatings pigmented with chromite iron nickel black and manganese ferrite black spinel colorants are not cool enough to be energy efficient cool black coatings. The cool black coatings pigmented with NIR-t...

Calcium tannate was synthesized, characterized, and dispersed into an epoxy coating as inhibitive pigment. Electrochemical Impedance Spectroscopy (EIS) employed to monitor the anti-corrosive performance of formulated with as-prepared pigment after exposure salt spray chamber. Reference coatings commercial calcium phosphate unpigmented were also evaluated for comparison reasons. EIS results show...

The formulations contained different acrylate monomer with different structure and functionalities and TiO2, were applied to obtain pigmented acrylic films by UV exposure. The conversion and mechanical characteristic were correlated. The results showed that there is a significant interaction between pigment, reactive diluents’ type and mechanical properties of coatings. It seems that cured film...

It is well known that the behavior of diverse multicomponent systems such as fibrous composites, particle—filled polymers, polymer blends, and pigmented coatings depends not only on the composition, morphology, and properties of the constituents, but also on the nature of the interfacial region. This paper reviews typical examples, with emphasis on interpretation of interactions between constit...

isolation of pigmented t.violaceum from a patient with endothrix infection associated with the inflammatory and kerion symptoms and also isolation of the non- pigmented strain from another patient with non-inflammatory symptoms, led us to investigate the enzymic activities in both strains. most of the studies on dermatophyte compoxition have shown the relationship between proteolytic enzymes an...

A general overview of visible light photoinduced polymerization reactions is presented. Reaction mechanisms as well as practical efficiency in industrial applications are discussed. Several points are investigated in detail: photochemical reactivity of photoinitiating system (PIS), short overview of available photoinitiators (PIs) and photosensitizers (PSs), mechanisms involved in selected exam...

Powder coatings are a green alternative to conventional solvent-borne liquid coatings, but they have the intrinsic drawback of color-matching and adjustment in production with extrusion process. In this study, an industrially applicable approach formulate color powder utilizing ultrafine powders, i.e., powdery blending pressing method, was invented. This novel method validated by comparing samp...
