Organic coatings, composition fillers

Silica powder, glass beads and fibres are commonly used for the reinforcement of plastics. The produced composite materials have an increased thermal and mechanical stability, compared to the pure polymeric material. In order to bind the inorganic filler to the organic matrix, silane molecules, with both an inorganic and organic side, are used. The silane may be mixed with the matrix and filler material in the composite preparation, or be coated onto the filler prior to mixing. The application... 

The opacity is a critical property if the starch-based films are used for food coatings applications. Transparent films are characterized by low values of the area below the absorption curve. The obtained values showed that films with addition of organic acid modified starch microparticles CMSt were more transparent than films with no chemically modified starch [74]. Besides, the opacity of films decreased due to addition of CMSt, this tendency being more noticeable in sample modified with tartaric acid. Film opacity decreased in order TAMSt/Stcellulose filler composite samples is represented [75].
