Directions for use
Clean-up: Clean up the surface to be bonded, making it clean and dry. For surfaces with low surface energy, it is recommended to use Huitian special cleaners;
Gluing: Using glue gun or other application tools to apply the glue. The product can be used after the not well-mixed part at the front end is removed by applying contact pressure and the two components are visually inspected to be well mixed;
Curing: Room temperature curing or heat curing.
