Packaging and storage	Comens Bondmelt 950 is packaged in 30 mL PP tube or 310 mL aluminum tube or 5 gallon iron drum and is recommended to be stored at 8-25ºC for 6 months. Storage at 12ºC is helpful to prolong the storage life of the product. Long-term exposure to the environment above 25ºC can shorten the storage life of the product. Do not expose products to high temperature and humidity environment. Recommended storage environment: ventilation, drying and shelter.
Supporting equipment	It is suggested that the equipment recommended by our company (dispensing machine/handheld glue gun/PUR hot melt glue machine) be used for sizing.
Surface cleanliness	In order to achieve the desired adhesive effect, it is recommended to clean up the dirt and oil on the surface of the substrate in the following way: Metal substrate: alcohol wipe 1 times. Plastic substrate: 2 times with alcohol.
Matters needing attention	This product is not inflammable. Wear protective glasses and protective gloves to prevent contact with skin and eyes during use. If you touch the skin carelessly, rinse it with a large amount of soapy water. If you enter the eyes, rinse it with a large amount of clear water for 15 minutes and see a doctor immediately. Please do not swallow. If you are not careful, please seek medical attention immediately. Please store this product in places where children can not reach it. Keep the container closed, away from heat source, open fire, and avoid direct sunlight. For more safety information, please refer to this product MSDS safety data sheet.
