How to use epoxy resin AB glue? Quick answers!! 30

When choosing an epoxy adhesive, a number of factors should be considered. Here are some small experiences that I hope will help you. As a high-performance, high-value-added adhesive, epoxy resin adhesive is highly valued by the industry, but at the same time, counterfeit and shoddy products are often patronized.

Therefore, we can identify it by the following chemical methods. The first method: dissolve the sample in sulfuric acid, then add concentrated nitric acid, and pour a large amount of sodium hydroxide solution, if it is yellow, it is generally epoxy resin.

The second type: drop 5 drops of concentrated nitric acid on the resin adhesive film, move the reactant into the test tube after a few minutes, add 6ml of acetone and then add potassium hydroxide ethanol solution to make it alkaline, if it turns from red to purple, it indicates that it contains epoxy resin glue containing bisphenol A type, this method is also intuitive; Method 3: Take....

AB epoxy adhesive is different according to the use time, the operation is also different.

1.Fast-curing type, the method of using this AB glue is to apply A glue (of course, B glue can also be used) on the surface of the adhesive, not too thick; Then apply B glue (of course, A glue can also be used).Then close the other adhesive object.

There is another way: there is a mixing cylinder on the market: the two rubber cylinders can be divided into AB glue, and a mixing tube is connected below, and there is a stirring screw in the mixing pipe.

After loading the AB glue separately, as long as the two cartridges are pressurized and pushed inside, the glue will be mixed into the mixing tube, so that it can be coated into the dispensing part.

2.For AB glue that can be used for a long time, the AB glue can be mixed according to the proportion provided by the first supplier, and stirred evenly with a glass rod. According to your operation requirements, look at the consistency (the AB glue will become thicker and thicker until it is fully cured), and apply the glue at the appropriate time.

Hope it helps.

According to the use of the epoxy resin AB glue you bought, but you must remember that the glue must be mixed well, and then it can not exceed the usable time of the glue, otherwise it will dry out, but if you buy a slow-drying type, you can also heat it to make the glue dry faster.

Epoxy resin glue has a curing agent, you stir the main agent first, and stir together to see what the proportion is, and adjust how much you can use, because this is two proportions that will be cured within a certain period of time. You don't understand and ask first.

After mixing the two doses of AB according to the regulations, stir evenly, coat the substrate, and press lightly.

Mix and stir in the appropriate proportions. I don't know what kind of epoxy AB glue you are, what kind of products to make, there are different ways to use it, such as to understand a little deeper to write out what to do, whether it is surface coating or pouring, watering, there are different ways of operation.

If you really don't know how to do this, you can put a mixture of A and B into the AB mixer, and then apply the glue through the mixer gun to the product you want to bond.

First look at the manual to see what its weight ratio is, and then take a clean container and pour A glue, pour B glue according to the weight ratio, and stir well.

Glue dropping procedure: 1. Prepare the following equipment: electronic scales, disposable plastic cups (or toothpicks, syringes), ovens (or greenhouses), vacuum, glue dropping machines, etc.

2. Take the amount according to the proportion, and the weighing is accurate, please remember that the ratio is the weight ratio rather than the volume ratio, and the A and B agents need to be fully stirred evenly after mixing to avoid incomplete curing.

3. Pour it into a glue dropping bottle, or suck it into a syringe, and then drop it into the appropriate position of the work.

4. Put the dripping work into the oven or greenhouse, which can be cured after appropriate temperature and time, and can also be cured naturally when the temperature is high and the relative temperature is small.

Precautions: 1. Agent A and B are mixed according to the specified weight ratio, and the chemical reaction of the two polymer chemicals A and B is fully and completely carried out, which is a prerequisite for fast curing and producing an ideal surface.

2. The more glue mixed together, the faster the reaction will be, and the faster the curing speed will be, please pay attention to control the amount of glue at one time, because due to the accelerated reaction, its usable time will also be shortened.

3. Several ways to prevent steam drums:

a. Configure an appropriate amount of glue each time to use it up within 30 minutes after matching, because the total viscosity of the dropping temperature after the preparation will be.

Constantly rising, not conducive to self-defoaming.

b. Use fire roasting or hot air to sweep the glue surface to eliminate bubbles and surface moisture, but do not use too quickly, too large to prevent the glue surface from scorching or boiling.

c. When using high-viscosity A and B glues, vacuum deaeration is necessary if necessary.

4. Cover the A and B agents at any time when they are not in use, and store them in a cool place away from light, so as not to absorb moisture and may cause fogging on the glue surface, if you find that the stored A agent or the A agent that has been adjusted or the color paste is turbid or flocculent, put it into 60 -80 and bake for about 6 hours to restore its original state.

5. Before using a large number of products, please try a small amount to master the skills of the product to avoid mistakes.

6. When the configured epoxy is left, it cannot be put back into the unconfigured bottle or can.

7. Do not add other diluents when dispensing, so as not to affect the performance, and the used tools can be cleaned with acetone or alcohol if needed.

8. Dropping glue (especially agent B) and ** contact, may make individual people allergic, for allergies, please wear work gloves to work, if accidentally contacted, wash with water quickly, if accidentally splashed into the eyes with water rinse, and see a doctor.

1. The sticky matter will be treated and cleaned at room temperature, and then the A glue and B glue will be mixed in a visual ratio of 1:1.

Apply to the surface to be bonded within minutes and fix it for 5-10 minutes.

The glue can reach 50% of the highest early strength after 30 minutes of lamination, and the highest strength after 24 hours. Available in -60 -100 environments.

1. Epoxy resin is an organic compound containing two or more epoxy groups in the molecule, and their relative molecular weight is not high except for a few. The molecular structure of epoxy resin is characterized by the presence of active epoxy groups in the molecular chain, which can be located at the end, middle or in a cyclic structure of the molecular chain.

2. Because the molecular structure contains active epoxy groups, they can be cross-linked with various types of curing agents to form insoluble polymers with three-way network structure. All polymer compounds containing epoxy groups in their molecular structure are collectively referred to as epoxy resins.

3. The cured epoxy resin has good physical and chemical properties, it has excellent bonding strength on the surface of metal and non-metallic materials, good dielectric properties, small variable shrinkage, good dimensional stability of products, high hardness, good flexibility, and stability to alkali and most solvents, so it is widely used in various departments of national defense and national economy for pouring, impregnation, laminating materials, adhesives, coatings and other uses.

No. Epoxy resin is a material that can be used to make AB glue, as well as other things such as floor paint.

AB adhesive is the name of a two-component adhesive.

Usually the A component is an acrylic modified epoxy or epoxy resin.

One liquid is the glue, the other is the hardener, and the two liquids are mixed to harden. AB glue with acrylic, epoxy, polyurethane and other components is commercially available. When used in the factory, in order to distinguish it from the conventional large cans (1 kg and 2 kg sets), epoxy resin, the abbreviation of the toothpaste tube is AB glue (the eye-catching name on the box).

What is commonly used refers to acrylic modified epoxy adhesive or epoxy adhesive. Component A is an acrylic modified epoxy or epoxy resin, or contains catalysts and other additives, and component B is a modified amine or other hardener, or contains catalysts and other additives. Mix in a certain proportion.

Catalysts can control the curing time, and other additives can control properties (e.g., viscosity, rigidity, flexibility, adhesion, etc.). The performance of AB glue sold on the market has been determined in the formula, and the general change is not large, and there should be a large change, which needs to be customized to the manufacturer.
