  • 1. Preservation of Adhesive SealantIntroduction of Adhesive SealantAdhesive sealant is mostly the carrier of high-molecular substance and it achieves curingrelying on a chemical reaction or physical action, these will occur slowly in the process ofadhesive storage. And adhesive sealant has a certain period of storage which is closelyrelated to the humidity, temperature, ventilation and other factors. In order to ensure that theperformance of adhesive is kept the same within the prescribed time, we should pay strictattention to the methods of maintaining the adhesive sealant. Storage conditions are differentfor its different nature and kinds.Methods to Maintain Adhesive SealantFirst, epoxy adhesives should be stored in ventilated, dry and cool room with appropriatetemperature and the period should be six months to a year. Second, phenolic resin adhesivesealant should be installed in a closed container, stored in a cool place, away from fire andits period should be six months to one year. Third, the multi-isocyanate adhesive sealantshould be loaded into a brown bottle with dark cryogenic storage, rubber and cork stoppersand metal containers cannot be used. And do not permit water to enter, otherwise it willcause polymerize deterioration and prepolymer polyurethane adhesives should avoidcryogenic storage to prevent condensation. Fourth, storage temperature of urea-formaldehyde resin smt adhesive should be as low as possible. Adding 5% methanol canimprove the storage stability. Fifth, chloroprene rubber adhesive containers must be sealledbetter. And it should be stored at room temperature, and the temperature cannot be too high,in addition, it should be away from the fire source. The period of storage is 3 to 6 months.Sixth, anaerobic adhesive should be stored in a cool, dark place, the storage period is sixmonths, and the packaging material of the container should be polyethylene instead of ironcontainer and cannot be filled. Seventh, SGA adhesive sealant should be sealed and stored,and the two components have to be isolated and placed in a cool, ventilated and dry place.Eighth, inorganic adhesive sealant should be sealed and stored, to prevent moistureabsorption. Ninth, hot melt adhesive should be stored away from light and it should be storedin room temperature with heat insulation.The Correct Selection of Adhesive SealantIn terms of bonding, the adhesive sealant is the base. It is impossible to bonding firm withoutproper adhesive sealant. Existing adhesives are not a panacea, they have a certain range ofapplications, therefore, it cannot be arbitrarily used, while it must depend on the type of the
