Each product has a storage period. According to international and domestic standards, the storage period refers to the situation at room temperature (24°C). For acrylate adhesive products, it is 20°C.
For acrylate products, the higher the temperature, the shorter the storage period.
For water-based products, if the temperature is below -1°C, it will directly affect the product quality.
II. Strength
There is no universal adhesive in the world. For different materials to be bonded, it is best to choose a special adhesive.
If the strength of the material to be bonded itself is low, there is no need to choose a high-strength product. Otherwise, it will be a waste of resources and increase the cost.
Don't just focus on high initial strength, but also consider good durability.
The performance of adhesives cured at high temperature is much better than that of those cured at room temperature. If high strength and good durability are required, choose high-temperature cured adhesives.
For α-cyanoacrylate adhesives (such as 502 super glue), except for emergency use, small-area repair, and continuous production, it is not advisable to use them for materials requiring high bonding strength.
III. Others
White latex and urea-formaldehyde adhesive cannot be used to bond metals.
For adhesives requiring transparency, you can choose polyurethane adhesives, optical epoxy adhesives, saturated polyester adhesives, and polyvinyl alcohol acetal adhesives.
The adhesive should not be corrosive to the material to be bonded. For example, polystyrene foam board cannot be bonded with solvent-based neoprene adhesives.
Adhesives with high brittleness are not suitable for bonding soft materials.
