The importance of coating preparation

China Paint Online News Information:
Coatings are divided into single and multi-groups according to ingredients, according to the material nature is divided into milk-based, solvent-based, hot-melt type, no matter which paint in storage, static will have different degrees of precipitation or layering, so must be stirred before use. For two-group or multi-group coatings, generally mostly reactive materials, so must be weighed accurately according to the requirements, strict reference to the order of feeding, and fully stirred evenly. Weighing is not allowed, stirring unevenly, will cause two groups of ingredients are not fully reflected, the coating film is difficult to cure or affect the quality of the coating film waterproof material layer after curing. In many engineering examples, many two-part coatings can not conjunctivate or produce presumed matter after construction, resulting in waterproof material layer quality problems, that is, the paint ratio is not allowed or stirring unevenly caused.
