Their producers are faced with the challenges of selecting binders that will ensure proper binding at very high PVC levels. This article introduces the principles behind the formulating and optimising of low-cost emulsion paints on the European market, and looks at case studies for assessing dirt-pick-up resistance and dry-rub resistance. A later article will present the results of wet scrub resistance and the final conclusions. Note de contenu : - Formulations for low-cost interior emulsion paints

In brief, essential oils of Thymus zygis, Citrus limoniumand Cinnamomum cassia microencapsulated as per the standard protocol followed elsewhere. The obtained microcapsules characterized, fused on to the foot bed materials of footwear using hand sprayer and assessed the antimicrobial property after airdrying. The foot bed material chosen for the present study includes leather, textile and polymer. Representative standard Gram -positive and Gram – negative bacterial species, and few of the fungal species isolated from leather samples are the test organisms used in the present study. Results revealed the size of the microcapsules as 25-60 nm. Optical and Scanning electron micrographs suggested the spherical nature of the capsules. Antibacterial and antifungal activity studies on microcapsules as such and foot bed materials before and after the incorporation of microcapsules infers the complete inhibition of microbial growth in microcapsules incorporated foot bed materials. The stability studies on the spray coating of microcapsules on to the foot bed materials reveal more than six months stability. SEM analysis of fungal species before and after exposure to microcapsules suggested the thinning of filaments and the natural mechanism of growth inhibition. In conclusion, coating of microencapsulated essential oils adds antimicrobial property to the foot bed materials. Note de contenu : - Chemicals
