The correct usage method of epoxy resin

Classification specification for epoxy resin

There is currently no unified classification for epoxy resin. Classified by ordinary strength, heat resistance level, and characteristics. There are 16 types of epoxy resin, including universal adhesive, layout adhesive, high-temperature adhesive, low-temperature adhesive, water wet surface adhesive, conductive adhesive, optical adhesive, spot welding adhesive, epoxy resin film, foam adhesive, stretching adhesive, soft material adhesive, sealant, and special adhesive. There are 16 types of ambush curing adhesives and civilian equipment adhesives.

In industry, the classification of epoxy resin adhesives can also be divided into the following categories:

1. According to its essential components, it can be divided into pure epoxy resin adhesive and modified epoxy resin adhesive;

2. It can be divided into machine epoxy resin adhesive, equipment epoxy resin adhesive, electronic epoxy resin adhesive, repair epoxy resin adhesive, transportation adhesive, marine adhesive, etc.

3. According to the construction premise, it can be divided into room temperature curing adhesive, low-temperature curing adhesive, and other curing adhesives;

4. According to its packaging form, it can be divided into single component glue, two-component glue, and multi-component glue;

There are other techniques, such as solvent-free adhesives, solvent based adhesives, and water-based adhesives. However, component classification is widely applied.

When applying epoxy resin, it is usually necessary to use it together with the epoxy resin curing agent. Before application, the epoxy resin and epoxy resin curing agent should be mixed in a 1:1 ratio, thoroughly stirred, and then applied to the area to be bonded.

If the epoxy resin is bonded to a straight or inverted surface, after applying the mixed solution of epoxy resin, it is necessary to use tape or 502 to fix the adhesive to prevent the adhesive from shifting and affecting the bonding effect of the epoxy resin.

In order to ensure the bonding effect of epoxy resin, it is necessary to control the temperature between -50 ℃ and 150 ℃. If it is at room temperature, the epoxy resin will basically cure around 6 hours after coating. If the temperature is 40 degrees, it will solidify in about 3 hours.

If you want to thoroughly clean it, it takes about ten days, and the bonding effect is better at this time. Before applying epoxy resin on rainy and humid days, it is usually necessary to heat the indoor temperature to around 20 degrees Celsius.

Before applying epoxy resin, it is necessary to wipe the surface of the object to be bonded first, and then use a cloth dipped in a cleaning agent to wipe it, achieving the goal of comprehensive cleanliness. Due to the fast curing speed of epoxy resin, the prepared epoxy resin mixture needs to be applied in a timely manner, otherwise it cannot be used after curing, resulting in material spreading.

To prevent the handle of epoxy resin from getting dirty, it is recommended that you wear gloves when applying epoxy resin. If the skin accidentally comes into contact with epoxy resin, wash your hands with soap. If the eyes accidentally come into contact with epoxy resin, it is necessary to clean the eyes with clean water in a timely manner. If you are very nervous, it is necessary to seek medical treatment at the hospital in a timely manner.

If epoxy resin is to be widely used, it is necessary to ensure good ventilation during construction to prevent the occurrence of fireworks and firecrackers. If a large amount of epoxy resin leaks, open the doors and windows for ventilation, pay attention to fireworks and firecrackers, and then use sand to supplement the position of epoxy resin, and clean the epoxy resin with sand
