1. Each product has a storage period. According to international and domestic standards, the storage period refers to the condition of normal temperature (24 ℃). Acrylate adhesive is 20 ℃.
2. For acrylate products, the higher the temperature, the shorter the storage period.
3. For water-based products, if the temperature is below minus 1 ℃, it will directly affect the product quality.
1. There is no universal adhesive in the world. For different adherends, it is best to choose special adhesive.
2. If the strength of the adherend itself is low, it is not necessary to choose high-strength products, otherwise, it will overuse and increase the cost.
3. We should not only pay attention to the high initial strength, but also consider the good durability.
4. The performance of high-temperature curing adhesive is much higher than that of room temperature curing. If it is required to have high strength and good durability, high-temperature curing adhesive shall be selected.
5. For a cyanoacrylate adhesive (502 strong adhesive), in addition to emergency or small-area repair and continuous production, materials requiring high bonding strength should not be used.
1. White latex and urea formaldehyde glue cannot be used to stick metal.
2. For adhesives requiring transparency, polyurethane adhesive, optical epoxy adhesive, saturated polyester adhesive and polyvinyl acetal adhesive can be selected.
3. The adhesive shall not be corrosive to the adherend. For example, polystyrene foam board, solvent chloroprene adhesive can not be used.
4. The adhesive with high brittleness should not stick to soft materials.
1. For ab component adhesive, please mix it according to the requirements of the manual.
2. The AB component adhesive must be fully stirred before use. No dead corners shall be left, otherwise it will not solidify.
3. The adherend must be cleaned without water (except underwater curing adhesive).
4. In order to achieve high bonding strength, the adherend shall be polished as much as possible.
5. The design of bonding joint determines the bonding strength.
6. When the adhesive is used, it must be prepared and used now. It must not be left for too long. In case of rapid curing, it should not exceed 2 minutes.
7. The thicker the adhesive is, the better the curing effect is. If it is too thick, the better the bonding effect is. 7. If it is too thick, it should not be visible.
8. When bonding objects, it is best to press or fix them with clamps.
9. In order to improve the strength, it is better to leave it for 24 hours after bonding.
10. For single component solvent type or water agent type, be sure to stir evenly when using.
11. For solvent products, after gluing, it is better to cool them until they are not sticky, and then glue them.
