Suggestions Operating Conditions
 Before gluing, choose corresponding treatment agents for various materials;
 Apply glue after the treatment agent is fully dried, and the amount of glue applied should be uniform to avoid uneven thickness or lack of glue;
 The combination of this product and our curing agent can effectively improve its heat resistance, water resistance, grease resistance and other properties. Suggested dosage: 3% to 5%;
 The curing agent is more likely to react with moisture in the air, etc. After use, it should be tightly closed immediately to avoid deterioration;
 After gluing, the drying temperature should be set between 60°C and 70°C, and the drying time should be 4 to 5 minutes;
 When laminating, you should choose the best sticking time for lamination, align once, and try to avoid pulling apart and laminating again. After pasting, be sure to complete all pressurization actions within the stickiness maintenance time. Missing the best pasting time may lead to poor adhesion;
 When using a finishing agent to remove pollutants on the shoe surface, prevent the solvent from penetrating into the adhesive layer and destroying the crystallization, resulting in poor bonding;
 When the product is transformed by objective factors such as weather, if there is any difference in operation, process and quality, please contact our technical department in time to solve relevant problems in a timely and effective manner.

Save Conditions
Storage sealed and protected from light, the storage temperature range is controlled at 5-30°C, and the storage period should not exceed six months, do not mix with other adhesives of different properties.
