 2. Sizing: Apply the glue to the gluing part of the corresponding substrate manually or using dispensing equipment.

 3. Curing: This product is a moisture-curing material. Its surface drying and curing speed depend on the relative humidity, temperature and thickness of the glue (2mm) in the environment where the material is used. Generally, it is under the conditions of 25oC, RH: 50~60% It can be put into use after curing for 24 hours, and reaches the best design performance after 7 days. The surface dry time will be extended with the storage time. Generally, the surface dry time can be maintained within 3 to 10 minutes within 3 months from the date of production. Please use it with caution when it exceeds 30 minutes.

 4. Precautions: After opening, the unused glue should be sealed and stored immediately. When using it again, if there is a little crust on the seal, it can be used after removing it without affecting the performance of the glue.

(4) Storage and validity period
