PRODUCT DESCRIPTION
Epoxy injection adhesive is a two component adhesive, with standard viscosity. Epoxy injection is a common procedure used to repair cracks in concrete structures. This adhesive is designed to be used with automatic meter, mix, dispense and injection equipment. Volumetric ratio for mixing the components of this adhesive id 4:1. The surface of concrete must be cleaned from any bondinghibiting substances.
This product is produced on the basis of very thin epoxy resins and is used for injection into capillaries and micro-cracks (with a width of more than 100 microns) in members of structures such as columns, beams, foundations, walls and floor parts. This product causes permanent blockage from the injection. It also connects concrete sections structurally and has the ability to make structural parts in one piece. An important feature of this product is its compatibility.

Frequently Asked Questions
Why is injected epoxy resin used?
After injection, this product causes permanent blockage of cracks and pores against the penetration of invading liquids and gases. It also connects concrete sections structurally and has the ability to integrate structural parts.
How many components is an injection epoxy resin made of?
Injectable epoxy resin is made of two hardening and curing agents.
Are colored injection epoxy resin components available?
Component A is a clear liquid, component B is an amber liquid, and finally is a pale yellow liquid.
What is the mixing ratio of injection epoxy resin components?
The components are combined in a ratio of 4 to 1. In fact, for every 4 components A, 1 component B must be mixed.
What should be the appropriate width for crack injection?
Suitable crack width for injection is 0.1 to 9 mm.
What is the age of concrete bed to apply injection epoxy resin?
The age of the substrate concrete for applying the resin should be between 21 and 28 days, depending on the curing and drying conditions.
What are the properties of injection epoxy resin?
They have desirable properties such as excellent adhesion, chemical resistance to acids, low drop, low curing time and moisture resistance.
What is the important and unique feature of epoxy injection resins?
An important feature of epoxy injection resins is high compatibility with moisture.
What is the price of injection epoxy resin?
Due to the nature of epoxy resin, which is a polymer product and is mass-produced, consumers can buy the product in the market with a wide range of prices. For information on the price of our company's products, you can contact the Afzir company experts.
