Also known as agglutinating agent or coagulant, it is a substance that can make unstable colloidal particles (or particles formed in the process of coagulation) gather together to form agglomerates. coagulant is usually used in the latex dipping process to make the liquid latex form a solid film. coagulant can be divided into three categories: coagulant, gelling agent and thermosensitive agent: coagulant: a kind of material that can quickly coagulate and agglomerate macromolecule materials, and is usually added to latex. Coagulants include acids (such as hydrochloric acid, neutral acid, acetic acid and other organic acids), metal salts (such as calcium chloride, calcium nitrate, barium carbonate, zinc chloride and other bivalent and trivalent metal salts), organic solvents mixed with water (such as ethanol, acetone, etc.), organic solvents mixed with polymer (such as benzene, carbon tetrachloride, etc.), and cationic surfactants (such as cetyl ammonium bromide, etc.). These coagulants are mainly used in the production of various latex gloves, weather balloons, holiday balloons, rubber hoses, finger covers, medical and health products, and rubber rings. Gelling agent: Gelling agent is a kind of substance that can make latex gradually transformation from liquid to uniform semi-rigid gel and maintain its original shape and size. They are mainly used for the preparation of latex foam. Some common gelling agents include fluorosilicates such as sodium fluorosilicate and potassium fluorosilicate. Thermosensitizers: Thermosensitizers are a type of substance that does not change the stability of latex at room temperature, but can quickly coagulate when the latex is heated to a certain temperature. Some common thermosensitizers include polyethylene methyl ether, polyether polyoxymethylene dimethyl acetal, polyphenylene glycol, etc. These thermosensitizers can be used to prepare products such as rubber hoses. coagulant plays an important role in the latex industry, helping to control the solidification process of latex to obtain the required shape and performance.
