If it is used in the industrial field, requires attention to quality, so how to determine the quality of the hot-melt adhesive? Material as the temperature rises, the volatile gas concentration grows, are smell the smell of the heavier, vice scent is light. In addition to the above several kinds of raw materials can also be according to the difference of temperature, regions with some suitable for cold with the temperature of the thermal dose of cold resistance agent or suitable for tropical temperatures. ( 2] Oxidation - - Reduction system is made up of two or more components. Smell is the inherent nature of the material, is one of the important features, material can be measured. How much is the product selection of yancheng henkel laminating adhesive shall be conducted according to GB/T 2792.
