Open time ≥5min Coating temperature 90-110℃ Melt temperature 90-110℃ Coating methods Roller coating Glue amount The general coating amount is 6-10 g/㎡, for reference only. Preprocessing The substrate needs to be clean, dry and free of grease. For low surface energy substrates, corona or flame treatment may be required. Preparation before gluing Please prepare the adhesive melter, heating plate, feed pump and discharge gun, and set the appropriate temperature. Excessive heating will cause the adhesive to decompose. It is recommended to use it below 130 degrees. Users who use glue melt tanks must use nitrogen for protection. The humidity of nitrogen must be below 5ppm, otherwise it will accelerate the formation of skin. After opening the package, please use it up as soon as possible. Curing conditions In order to achieve complete curing, the compounded product can be stored at a suitable temperature and humidity (e.g. 25°C and 50% RH, or above). Under suitable conditions, curing will be completed within 7 days. At lower temperature and humidity, it will take longer to achieve complete curing. 3.Storage and safety
- In a dry and clean environment at 5-30℃, the shelf life of the original unopened product is ≤9 months. The opened but unused product should be used up as soon as possible.
- Be careful! Empty containers of adhesive also contain hazardous materials. Please follow the instructions on the container label and do not use empty containers without professional cleaning.
- If you need more safety information, please refer to our product safety data sheet.
