#BINFER IN DENTIFRICE SKIN#

Glue is traditionally made by the boiling of hoofs, bones, or skin of animals and then mixing the hard gelatinous residue with water. Materials include wax, linseed oil, natural gums such as gum arabic or gum tragacanth, methyl cellulose, or proteins such as egg white or casein. Compressive strength can be improved by adding filling material.īinders hold together pigments and sometimes filling material to form paints, pastels, and other materials used for artistic and utilitarian painting. Tensile strength is greatly improved in composite materials consisting of resin as the matrix and fiber as a reinforcement. Other binding agents such as resins may be tough and possibly elastic but can neither bear compressive nor tensile force. Some materials labeled as binders such as cement have a high compressive strength but low tensile strength and need to be reinforced with fibrous material or rebar if tension and shear forces will be applied. 8-16 atm pressure and, e.g., comprise CaSiO3 materials). For example, in the compound WC-Co (Tungsten Carbide used in cutting tools) Co constitutes the binding agent for the WC particles.īased on their chemical resistance, binders are classified by the field of use: non-hydraulic ( gypsum, air-cements, magnesia, hydrated lime), hydraulic ( Roman cement, portland cement, hydraulic lime), acid-resistant ( silicon fluoride cement, quartz cement), and autoclavable (harden at 170 to 300°С i.e. These can be either metallic or ceramic as well as polymeric depending on the nature of the main material. Binders are loosely classified as organic ( bitums, animal and plant glues, polymers) and inorganic ( lime, cement, gypsum, liquid glass, etc.).
