Instructions for use of carbon fiber coating primer

 

Compared with some so-called quick-drying primers with low viscosity (quick-drying and brittle, and easy to delaminate after exposure to the sun in summer),

The carbon fiber coating primer of this product uses E51 epoxy resin (A) and an improved high bonding and high adhesion curing agent (B). It has the advantages of good toughness, strong adhesion, high peel resistance, and not easy to delaminate after being exposed to the sun in summer. This is also the original intention of our store to choose this model as the carbon fiber coating base glue. However, some customers complained that the consistency of the base glue in our store is too high (caused by low temperatures in winter), which may cause inconvenience in use. This article will introduce in detail how to better use carbon fiber-coated base glue.

 

Scope of application: ABS plastic, aluminum alloy, iron, wood, ceramic (unglazed) and other polar materials (i.e. materials with painted surfaces or paintable surfaces)

 

Special Note:

First: Surface treatment of original parts

Use 320-grit sandpaper to dry-sand the surface of the wooden object, completely polish the paint surface, and keep the surface as rough as possible. Then use a utility knife to score the surface into a mesh to increase adhesion as much as possible.

Second: Preheat to reduce viscosity

When the temperature is lower than 20°C, the viscosity of the base glue (B) will increase. When the temperature is lower than 5°C, the viscosity of the base glue (A) will also increase. At this time, it can be preheated to reduce the viscosity. Easy to use in proportion. When the temperature is lower than 5℃, (A, B) can be preheated at the same time. Heating the insulated water for about 10 minutes will significantly reduce the viscosity and make it easier to use.

Third: Proportion

The color of primer (A) may precipitate if left to stand for a long time. Before mixing, you can open the bottle cap and stir it with a stirring rod a few times, or change the bottle cap and shake it up and down a few times.

According to A:B=1:1 (the volume ratio and weight ratio are the same), take the proportion and mix thoroughly before use.

Fourth: Painting

When painting, you can roughly apply it first. After brushing, use the hot air setting of a hair dryer or the low setting of a heat gun to blow the entire surface for 2-3 minutes to further reduce the viscosity and control the thickness of the entire surface to a minimum.

1: Use the hot air setting of the hair dryer, the non-adjustable low setting of the heat gun, and the adjustable setting of 150-180℃

2: Blow the entire surface for 2-3 minutes to further reduce the viscosity

3: Press the brush and scrape off the excess primer to achieve a moderate thickness (generally the same thickness as ordinary A4 paper)

4: After brushing, place it in the air. After a period of time, the surface will be level.

Special reminder: When applying primer, the brush must be pressed down to allow the primer to fully blend with the original piece.

Fifth: Waiting time

After applying the primer, you need to wait for a while to achieve the best viscosity when laying the carbon fiber cloth.

Please refer to the following for specific times

 

0-10℃ (it is recommended to take heat preservation measures below 0℃)----1.5-2 hours

10-15℃----about 1.5 hours

15-25℃----1-1.5 hours

25-30℃----about 1 hour

30-35℃----45-60 minutes

Bake at constant temperature 60-65℃ for 15-20 minutes

After the appropriate time, the stickiness will be very good when touched with your fingers, and it will look like a string, and you can lay the carbon cloth.

A word of caution: if the base glue is applied thickly or if the time is not enough, the carbon cloth may seep out of the surface of the carbon cloth and affect the effect.

 

Sixth: After laying the carbon cloth, the carbon cloth needs to be pressed firmly with the palm of your hand to make the carbon cloth fully fit the original part. After pressing the entire surface, you can wrap it with plastic wrap and tighten it (keep it wrapped for 1.5-2 hours). Further let the carbon cloth fit the original part.

 

At this point, the entire process of using the primer is over.

Use the primer according to the above method. After all is completed, the entire carbon fiber will be almost integrated with the original part, which can effectively prevent edge warping and separation and delamination.
