    1. Storage life
    a. Each product has shelf life, according to international standards and domestic standards, storage means that at a room temperature (24 ℃).Acrylic glue’s shelf life is 20 ℃.
    b. For acrylic products, the higher the temperature, the shorter the storage period.
    c. For a direct impact on product quality of water-based products if the temperature at minus 1 ℃ below.
    2.Strength
    a. There is not all-purpose adhesive on the world, you should use the proper adhesive to different materials.
    b. If the adherend stickness is low , then you don’t need to use high stickness adhesive, otherwise, would be overkilled and increasing costs.
    c. Not only attach importance to the initial strength, but also durability should be considered.
    d. High-temperature curing adhesive e’s proformance is much higher than room temperature curing,if you need high strength and good durability,you should use high-temperature curing adhesive.
    e.For a cyanoacrylate glue (glue 502) in addition to emergency or a small area of  repair and continuous production,if the material requires high stickness,it’s not proper to use it.
    3.Notes when using the adhesive
    a.When mixing the AB component adhesive, please mix according to the instructions.
    b. AB component adhesive must be fully mixed before your use.If not, it would not cure.
    c. Adherend must be clean and without water (except for underwater curing adhesive.)
    d. In order to achieve high bond strength, polished surface of the material as much as possible.
    e. The design quality of adhesive joint decides the level of bond strength.
    f. When using adhesive, must be present with current use, should not be left too long time, such as the fast-curing, it usually not more than 2 minutes.
    g. If you require high stickness and fast curing, you can heat them according to the actual situation.The adhesive’s tickness should not be too thick, 0.5mm is generally good, the thicker the worse is the bonding effect.
    h. When bonding object,there are preferably a fixed pressure or fixture.
    i. To make higher strength,it’s better to keep 24 hours after adhesion.
    j. One-component solvent-based formulations or water-based, should be fully mixed.
    k.For the solvent-based products, it should be sure to cool and set to the appropriate little sticky,then you can do further bonding.
