Shelf life refers to the time from the date of manufacture to the expiration of the product. Different products and models have different shelf life. For more information, please refer to the instructions of the product.

If there is a small amount of oil on the surface, thread locking adhesives and sealants can be used without surface treatment. If the pursuit of sufficient bonding effect, need to remove grease and pollution. For building adhesives and quick-drying adhesives, acceptance of finished surfaces must be determined by testing. In general, the end user should try to finish the surface with the least complexity.

Anaerobic adhesive, as the name implies is in contact with the air in the environment can occur chemical reactions to cure the adhesive. Under normal circumstances, the curing time of anaerobic glue is a few minutes to more than 10 minutes. The curing rate is different because of the material and the substrate. In addition, heating can accelerate the curing.

Skin: AA super adhesive can also be timely skin bonding is very tight, in case of accidentally put fingers together, not hard pull, but to use warm water or acetone and other solvents a little bit of rubbing;

Eyes: In case AA Super glue is sprayed into eyes, immediately wash eyes with plenty of clear water and seek medical advice (do not wash eyes with solvent or rub eyes);

Infants and children: AA super adhesive has a very strong adhesive force, for safety, please stay away from infants and children;

Air circulation: when AA super adhesive is liquid, it will have a pungent smell. When used in large quantities, pay attention to air circulation;

Heating reaction: AA super adhesive polymerization (curing), there will be a heating reaction, a large number of infiltration into the fabric or foam polyurethane rubber and other porous materials in the liquid curing, will produce considerable heat, if there are caustic soda or amine reaction accelerator, the heating reaction will occur and can release enough heat to cause combustion.

Humidity: AA super adhesive will be resinized by a small amount of water in the air, so pay special attention to humidity. Put the lid on and put it in an airtight box with a moisture-proof strip to avoid contact with the outside air;

Sunlight: AA super adhesive will turn into resin when exposed to ultraviolet light, please avoid direct eyes;

Temperature: When AA super adhesive is stored in a high temperature place, its original bonding strength will begin to decrease.Therefore, it is stored in a low temperature place as far as possible (if it must be stored for a long time, it is best to put it in the refrigerator and adjust the temperature to about 5℃-10℃).

Reactive hot melt adhesive, also known as PUR hot melt adhesive, solvent-free, short time can be cured, high adhesion, good heat resistance, through cooling curing, through moisture reaction hardening. Ultra-narrow frame dispensing, the finest can do 0.2mm dispensing (before pressing); Fast hardening speed, the fastest only need 0.5-3 hours to enter the next process; Good thermal stability, after a long time of heating can also be stable glue; Shading performance, both black and white glue has the essence of shading function; Heavy duty (repairable), by heating can be relatively easy to remove the attached parts. Can be used in mobile phones and other electronic terminals TP screen and front shell bonding, or other parts of the structure bonding.

UV hardening resin UV adhesive

The curing speed after ultraviolet irradiation varies according to the type of light source, irradiation distance and irradiation Angle.

The UV exposure required for full curing will vary with the amount of coating and the size of the coating area.

The ingredients of the adhesive sometimes erode the plastic;

Because of the long-term preservation of the filler may precipitate, when adding the filler, please stir thoroughly;

Once the adhesive has been removed from the container, do not put it back into the container. There is a possibility of contamination;

Container containing adhesive, do not place in the sun. Have the possibility of curing;

Containers with adhesive should be kept in the dark;

Do not freeze storage, may produce crystals;

It can be refrigerated, but the viscosity in the middle will increase if the bottle is removed from the freezer. Please return to normal temperature before use;

When discarding, please seal the container to dispose of industrial waste;

Single liquid epoxy resin

When heating and curing, the temperature and time must be fully managed;

Curing conditions vary according to the heat capacity of the coated material.

When the adhesive is injected into a micron size space, make sure it is cured. Because of the possibility of uncured;

Because of the long-term preservation of the filler may precipitate, when adding the filler, please stir thoroughly;

Once the adhesive is removed from the container, do not put it back into the container, there may be contamination;

It has the possibility of curing when stored at temperatures above 40 degrees Celsius. If it is cured, hot gas will occur and damage the container or produce gas;

Please keep in cold storage;

When discarding, please seal the container and dispose of it as industrial waste.

Two-liquid epoxy resin

The agent, curing agent, correct weight measurement, mixing and stirring under the specified ratio;

The mixture must be used within the allowable time and the viscosity will increase with time;

Because of the long-term preservation of the filler may precipitate, when adding the filler, please stir thoroughly;

Once the adhesive is removed from the container, do not put it back into the container, there is a possibility of contamination;

Containers with adhesive should be kept in the dark;

When discarding, please seal the container and dispose of it as industrial waste.
