Developed to be used for carbon fiber, this carbon fiber resin is a product used for carbon fiber stiffener and shows an excellent adhesive strength and coating characteristics. When carbon fiber sheets are reinforced for any weak structure such as poles, beams, chimneys, they show excellent reinforcement effect by increasing adhesive strength of the fiber with concrete's main body. Also, with less stiffening time, it shows excellent characteristics when laminating carbon fibers.For impregnating adhesion of carbon fiber and glass fiber

Pot Life The period of time during which you can work without a change in viscosity after resin And hardener are mixed.
Tack Free The state of hardening in which you can lightly touch the mixed resin with your hand, but the hardened material does not stick.
Hardening Time The time it takes for the mixed resin to be hardened enough to realize about 80% of final mechanical strength.

Coating work should be avoided when the site temperature is out of 5℃℃ ~ 30℃℃ range or its humidity is over 85%. Coating work should be avoided when concrete is wet or condensed or polymerized with more than 10% water content. To avoid condensation of water, coating surface temperature should be more than 3℃℃ higher than dew point and its relative temperature should be under 85%. Mixing of epoxy resin
Place the main material and the hardener of disposable carbon fiber primer on a mixing bucket by the weight ratio of 2:1. Mix them by using an electric mixer for about 2~3 minutes until you see the color of the mixture becomes even. Mixing of the main material and the hardener of impregnating resin is very important. You need to pay a close attention to mixing around the mixing bucket's walls and bottom. (Pay close attention during the work,since poor mixing or mixing rate may cause pseudo stiffening which may make stiffening impossible.) Base coat work of carbon fiber adhesive resin
Transfer the mixed impregnation resin to a proper distribution bucket and evenly coat them over the target surface using a roller coater. This type of coating resin is called base coat resin and its standard volume consumption is as follows;
① Unit weight of carbon fiber sheet 200g/㎡ : 400g ~ 500g/㎡ consumed
② Unit weight of carbon fiber sheet 300g/㎡ : 500g ~ 600g/㎡ consumed
Work from mixing of resin to impregnation and defoamation has to be done within its usable time. If more power is needed because the temperature of mixed resin for impregnation gets higher or its viscosity increases, it is an indication that its hardening time is over. Stop the work and dispose the remainder. A roller coater cannot be used again by cleaning with solvent. Therefore, you need to prepare enough roller coasters.Top coat work of carbon fiber adhesive resin
Coat the impregnating resin over the surface of the carbon fiber sheet between 30 minutes to three hours after impregnation and defoamation work. This type of coating resin is called top coat resin and its standard volume consumption is as follows;
① Unit weight of carbon fiber sheet 200g/㎡ : 100g ~ 200g/㎡ consumed
② Unit weight of carbon fiber sheet 300g/㎡ : 200g ~ 300g/㎡ consumed
Top coat resin should be coated evenly over the surface of the carbon fiber sheet and the roller must be moved longitudinally alongside the fiber during the coating work. A For any work where more than two layers of carbon fiber sheets are constructed, the second layer work should be done from base coat in the same manner used for the first layer after the top coat of the first layer is completely dried. Generally, the principle is one layer a day. Before the second layer work begins, defective areas should be fixed.All the equipments and tools that are used for this operation should be cleaned when the operation is finished. Detergent such as M.E.K, Acetone, Xylene, Toluene and epoxy thinner should be used when cleaning. If the Foam is smeared on your skin during the performance, wash it immediately with flowing water.- When you treating medical fluid, make sure you wear protective helmet, goggle clothes and other protective devices.
- All the hand tools and equipments that are used for this operation should be cleaned with thinner thoroughly.
- Never fail to abide by the designated mixture ratio, for it is the dual component type of the main material and the hardener.
- Acceleration or deceleration of the hardening speed through a random increase or decrease of the hardener will cause greatly reduce the post hardening properties.
- If the medical fluid is smeared on your skin and causes skin trouble, then you should go see Specialist for prescription.
- Mix the volume only that you can use up within the pot life.
- Pay attention to the fact that the Reaction speed of mixed resin becomes fast when the temperature is high or its volume is large, and slow when the temperature is low or its volume is small.
- If you are working in sealed room, then make sure to conduct constraint ventilation for clean air.Recommended temperature for storage is 10~25℃?with no moisture. Store it in cool area. Storing period is about 6 months in sealed condition however it can be corrupted according to storing area and conditions. Preferably use it as soon as possible.
