    Construction Recommendations

    1. Clean: Clean the dust, water, oil pollution on the surface of the product, and keep the surface dry.

    2. Stirring: Before the ratio, stir the A agent first to divide the pigment (filler) at the bottom into the glue liquid.

    3. Mix ratio: Weigh the product separately according to the A / B ratio of the purchased product and pour it in turn (* Note: according to the weight ratio, non-volume ratio).

    4. Mixing: Mix the mix of A / B glue, fully stir to avoid incomplete curing.

    5. Defoaming: The mixed glue static 5-10 bubbles will automatically discharge if conditions can be vacuum defoaming.

    6. Use glue: Pour the glue into the adhesive products, please use it up within the operational time.
