Epoxy Resin Adhesive

Afzir Multi-Purpose Epoxy Adhesive (Code 420™ERA) is a high-performance, solvent-free, 100% solid, two-component structural adhesive with high adhesion and exceptional durability. This product consists of two components: resin (component A) and hardener (component B), which can offer a wide range of mechanical, thermal and electrical properties with special formulas, and is very suitable for structural connections and strengthening structures.


What is multipurpose epoxy glue?

Multi-purpose epoxy glue is a two-component glue with strong adhesion and high strength. It is used for gluing all kinds of common construction materials. This solvent-free product has a simple one-to-one mixing ratio. It has a suitable concentration that allows it to be used on horizontal and vertical surfaces and has a good filling for split surfaces. After hardening, it can be drilled, cut or sanded. This glue is suitable for different types of surfaces: including steel, glass, concrete, fiberglass, wood, cement, brick, stone, tile and ceramic and many other building materials. This glue is very strong, waterproof and resistant to chemicals that does not loosen and shrink and is suitable for many indoor and outdoor applications.

How to mix multi-purpose epoxy glue

The mixing ratio is one to one by volume, one part part A and one part part B. Care must be taken to ensure that the multipurpose epoxy is thoroughly mixed. The entire amount of Part B hardener should be poured into the base of Part A and thoroughly mixed using a suitable drill at slow speed and mixing pedal. Blend for 2 minutes until a completely uniform gray color is obtained. The sides of the cans should be scraped, mixing should be stirred for 2 minutes. If it is overmixed, air bubbles may form in the mixture. To facilitate mixing and application at temperatures below 10°C, individual components must be warmed in hot water or room temperature conditions to a maximum of 25°C before mixing. If it is heated to 25 degrees Celsius, the working time of the mixture is reduced to 45 minutes. Alternatively, the material should be stored at 20°C and only removed immediately when needed. Mix only the amount of ingredients that can be used within the set time.

How to use multi-purpose epoxy glue

Use sandpaper to roughen the surfaces where you are going to stick the glue. You can also carefully file the surface. Clean the surfaces, making sure there are no traces of dirt, dust or grease.
Prepare the injection syringe. First, cut the end tip. Then turn the syringe upwards and press the plunger of the syringe. Wait about 30 seconds for the air bubbles to rise.
Get ready to mix. If you don’t have a mixer, don’t worry. On a disposable surface, use a double plunger to dispense resin and hardener in equal proportions. Ideally, you should purchase a tray for the epoxy in advance, but if you don’t have one, you can use a clean disposable plate or plastic container (like a yogurt pot) instead.
Pull back the plunger of the syringe. Clean the tip of the syringe and push the plunger again.
Mix epoxy resin and hardener quickly. They should be thoroughly mixed within a few minutes.
Apply a small amount of glue on the surfaces to be glued. Make sure they are in the right place and then press them together firmly. Processing times can vary, so check product instructions.
Remove the excess epoxy carefully. You can remove the excess epoxy with a cloth and methyl alcohol.

Application Instructions

The substrate surface should be prepared using mechanical tools such as sandpaper or sandblasting to remove any weak surface layers or brittle materials. The substrate should have an inherent tensile strength greater than 1 N/mm2. Pull off test should be done before adhesive installation. If the substrate is uneven, its surface should be leveled again with Afzir’s leveling mortars.

Metal surfaces:

Metal surfaces must be lubricated before application. Where there is no corrosion, cleaning with a wire brush is enough.


Epoxy components are usually prepared in two separate bins. Before combining them, each component should be well mixed individually to avoid possible sedimentation. Then add the hardener to the resin and stir for 3 to 5 minutes with a drill at low speed and a mixer. Continue mixing until the mixture is uniform and uniform in color. It is suggested that in cold weather, the glue is closed in a warm environment for a few hours and then used.


Mixed adhesive should be used during its lifetime. After combining the resin and hardener, you have about 90 minutes (at 21°C) to use the materials. Apply the adhesive under the prepared substrate with a roller or by hand if wearing gloves. Apply the material to both surfaces before joining together.

Press the sheets glued to the substrate. Use a rubber roller to press the screen to the substrate, making sure there is no air left between them. Use a roller to achieve an adhesion line with an approximate thickness of 2 to 3 mm. Remove excess adhesive from around the screen.

Guide to Quality Control (QC)

For best mixing, ensure that the temperature of the ingredients is around 22°C.
At low temperatures, if the product seems thick, before mixing, the mixture should be heated by placing it in a bucket of warm water.
If necessary; When the ambient temperature is high, cooling the multipurpose epoxy in water is recommended to prevent rapid scaling/hardening.
Place the buckets of part A and B separately in warm or cool water for at least 10 to 15 minutes. Then let the material return to room temperature (20-23 degrees Celsius).
The application temperature range is 35 to 115 degrees Fahrenheit and the service temperature range is -20 to +200 degrees Fahrenheit.
It shows excellent chemical resistance to mild acids, caustics, detergents, gasoline, fuel oil, salt and fresh water.
It does not stick to wax paper, Teflon, polyethylene and some other plastics. If you doubt whether it is suitable for the desired surface or not, test a small area.
