    Adhesives and other polymer materials for the soil, and some will add a certain amount of solvent, relying on chemical or physical effects to achieve curing, which in the custody of the adhesive process will occur slowly, therefore. Adhesives have a certain shelf life, which is related to storage conditions such as humidity, temperature, ventilation and so on. In order to ensure that the adhesive within the specified period of time the basic performance of the same, strict attention to the method of keeping the adhesive is necessary. For different types of adhesive, because of its different nature, storage conditions are not the same.

    Here mainly talk about lamination adhesive storage method, it should be in a ventilated, dry, cool, room temperature storage, for a period of six months to one year. Containers can not use metal containers, can not use rubber and cork stoppers. And prevent moisture into, or will occur polymerization metamorphism.

    Testing the durability of the lamination adhesive is a difficult thing, and some methods help to test the life of the adhesive, resulting in the actual time that the workpiece can be stuck, such as high temperature, aging and high humidity. The most accurate way to determine the bonding time of the workpiece is to allow the workpiece to age for a certain period of time. The best way to estimate the bonding time is to compare the product with a new product with a product that has been known to have a lifetime and performance ratio in the aging test to evaluate the bonding life of the new product. The longer the product's life expectancy is, the more important the aging of the product is.

    The four most commonly used sizing methods are spraying, dipping, brushing and flow coating (pouring). In most cases, the use of a lamination adhesive requires only a poor side of the adhesive. If a very fast cure time or a gap in the adhesive zone is required to have a gap greater than 0.15, it is usually necessary to double the bottom. When using the primer, the best less. If there is a small amount of oil on the surface of the adhesive, you do not need to do the surface treatment can use thread locking glue and sealant. To have sufficient bonding effect to remove grease thick film and contaminants. For building adhesives and quick-acting adhesives, the acceptance of the machined surface must be determined by testing. In general, the end user should try the least complex machining surface.
