FRP Primer

FRP epoxy primer (WEP ™ 240 code ) is the best choice for bonding between substrates and top layers due to its good viscosity and porosity permeability, as well as its high wetting property and good adhesion to concrete, metal and stone surfaces. WEP ™ 240 is a two-component epoxy primer suitable for preparing dry and wet surfaces. This product is used for saturation and impregnation of various woven and non-woven FRP fibers as well as a bonding layer in reinforcement operations in various ways, including FRP reinforcement by Afzir Reinforcement Company.


PRODUCT DESCRIPTION

WEP™240 Primer is an easy to use 4:1 volumetric mix, and cures quickly with low odor Epoxy primers are used for a wide variety of materials due to their strong adhesion, good mechanical ability, and durable chemical resistance in wet and high-humidity environments. The ability of an epoxy primer to resist corrosion is related to its thickness. WEP ™ 240, has excellent penetration into the fine cracks of building materials. Also, dilute epoxy primer creates a very good bond between building materials. The low concentration of epoxy primer allows this product to penetrate the capillary surface of the concrete and create a very strong bond with the concrete it produces a good surface finish.

Epoxy primers not only offer excellent adhesion to metals, but also serve as a proper base for extra undercoat and top coat products. Epoxy primers are also commonly used to coat metal cans and containers, especially those used to hold acidic food, such as tomatoes.

FRP Primer bonds well with minimal surface preparation and in the presence of moisture. However, it is recommended that contaminants such as standing water, rust and dirt be removed prior to application of FRP Primer. Substrate sanding or scuffing will enhance bond capabilities. FRP Primer does not bond well to some untreated plastics or surfaces contaminated with petroleum products.

Frequently Asked Questions

What is Epoxy Primer?

Frp epoxy primer is a two-component compound with low viscosity and concentration that is used to prepare the substrate before any repair and hardening operations. By applying epoxy primer to the desired substrate, the primer penetrates deep into small cracks or pores in the substrate and causes them to become blocked. This action increases and improves the mechanical properties of the substrate. In addition, the application of epoxy primers can help to better bond and reduce the consumption of resin in the installation of FRP products on concrete surfaces for reinforcement.

What is the property of epoxy primer?

FRP epoxy primer has good adhesion to most substrates such as concrete. In addition, its low viscosity, low concentration and high permeability make it easy to saturate the substrate and penetrate deep into the substrate. FRP epoxy primer is highly resistant to moisture and corrosion. These types of primers work quickly.

What are the uses of epoxy primer?

The most common application of FRP epoxy primer is to prepare the substrates before performing the retrofitting operation using FRP products. In addition, FRP epoxy primer, in order to block fine concrete cracks and improve the mechanical properties of hardened concrete, bedding for epoxy industrial flooring, primer for paint and flooring in sanitary environments, primer for fireproof coatings, stabilization Porous structures, etc. are used.

What is the penetration power of epoxy primer on surfaces?

FRP epoxy primer has high permeability. In such a way that it can block penetration and pores or small pores that cause moisture, destructive chemicals, etc. to the depth of the bed, such as concrete.

What is the gel time or working time of epoxy primer?

The working time of FRP epoxy primer at 25°C is about 90 minutes.

At what temperature can FRP epoxy primer be used?

The best temperature for maximum use of FRP epoxy primer is -35 to +65 degrees Celsius.

How to mix the components of FRP epoxy primer?

Shake each section well first. Part B is added to Part A and mixed for two to three minutes using a slow drill equipped with a suitable mixer, to obtain a uniform mixture. To make smaller volumes, pour one volume of Section B with 4 volumes of Section A in a clean container and mix well. Try to mix only the required amount of FRP epoxy primer, all of which can be consumed within the performance time or gel time.

What color is the epoxy primer?

FRP epoxy primer is made of two components A and B. Component A is a light yellow liquid and component B is a clear liquid. The combination of these two components ultimately provides a light yellow color.

What is the price of epoxy primer?

FRP epoxy primer is sold in the market in kilograms. Due to market fluctuations, the price of FRP epoxy primer also varies. Therefore, for detailed inquiries about the price of FRP epoxy primer, you can contact our experts in Afzir.
