What is the difference between an epoxy penetrating primer and a closed primer?

1. The resin raw materials used in the epoxy sealing primer are different.

2. Epoxy sealing primer is a curing material, and the curing material is epoxy resin.

The two-component material of the reinforcing agent can be cured after mixing, without air, and the curing time is relatively small due to the environment; Epoxy penetrating primer is an air-drying material, which needs to be cured under air circulation, needs to be breathable, is greatly affected by the environment, and has a long curing time.

3. The epoxy resin and curing agent in the epoxy primer should be cured smoothly according to a certain ratio, the ratio of epoxy sealing primer is 2:1, and the ratio of epoxy penetrating primer is 1:1.

4. Epoxy sealing primer is cheaper than epoxy penetrating primer, and it can be seen from point 3 that the amount of epoxy resin used in penetrating primer is relatively large, so the cost is relatively high.

5. The adhesion of epoxy penetrating primer is stronger than that of epoxy sealing primer, so epoxy sealing primer is mainly used for concrete.

Cement floors are the ones with large pores; Epoxy penetrating primers are used for tile, terrazzo and emery floors.

and other smooth ground, because its adhesion is strong enough, so it can be adsorbed.

What is the difference between an epoxy penetrating primer and a closed primer?

The so-called penetrating primer: that is, the product can penetrate 2-3mm into the foundation ground, so that the foundation ground and the painted epoxy coating have good adhesion, and it is not easy to delaminate and shell.

Closed. Primer: It is mainly to seal the moisture and moisture of the foundation ground, and do not run up.

The two materials of floor primer materials have their own advantages and characteristics.

The difference lies in them.

The function is different, one.

It is infiltration, and the other is closure.

Summary. The main difference between an erosion primer and an epoxy primer is their chemical composition and purpose of use. An erosion primer is a primer that contains organic acids and solvents, and its main role is to chemically react with the surface being coated to create better adhesion.

It can effectively remove the oxide layer, rust, oil, etc. on the coated surface, and at the same time provide good adhesion, making the upper coating film stronger. An epoxy primer is an epoxy resin-based primer that provides protection primarily by forming a hard, abrasion-resistant film. Epoxy primers have high resistance to chemicals and abrasion, effectively protecting the surface of the coated object from chemicals, abrasion and corrosion, while providing good adhesion to the upper coating film.

In summary, erosion primers are mainly used to remove impurities from the coated surface and provide strong adhesion, while epoxy primers are mainly used to provide protective films and enhance the chemical and abrasion resistance of coatings.

You've done a great job! Can you elaborate on that?

The main difference between erosion primer and epoxy primer is the composition and purpose of use. Erosion primers contain organic acids and solvents that remove impurities from the surface to be applied and provide strong adhesion. Epoxy cooktop primers are based on epoxy resin, which forms a hard film that provides protection and resistance to chemical corrosion and abrasion.

Permeable epoxy primer penetrates well.

The closed primer has good sealing performance.

Closed primers** are higher than penetrating primers**.

The difference between an epoxy penetrating primer and a closed primer is what substrate it is used on. This is a very professional question. Generally, high-quality and high-strength concrete floors (above C30) can use closed primers, on the contrary, the ground with poor ground strength needs to use epoxy polyurethane high permeability primer, epoxy polyurethane high permeability primer** should also be high into epoxy closed primer, epoxy polyurethane high permeability primer dosage is also larger, so the general ground business will not use epoxy polyurethane high permeability primer, because of the high cost.

The first component of the sealing primer is made of highly permeable epoxy resin liquid, and the second component is a special curing agent, which is suitable for the surface of concrete, wood, terrazzo, steel and other substrates as a sealing primer.

Feature 1: Strong permeability, excellent sealing performance, and can improve the strength of the substrate.

3. The coating has excellent alkali resistance, acid resistance and water resistance, and has good matching properties with the surface layer.

4. It can be brushed and rolled, and the construction performance is excellent.

The role of the sealing primer.

1) Seal the substrate, penetrate into the internal structure of the substrate, block the capillary pores in the substrate, reduce the number of open pores in the substrate, increase the number of closed pores, inhibit the penetration of paint moisture, make the penetration uniform, and make the absorption of the substrate on the upper layer of paint uniform.

2) The sealing primer can prevent moisture, resist alkali isolation, effectively isolate the alkali of the base layer, and prevent the exudation of alkali from damaging the coating.

3) Reinforcing the loose and weak substrate and strengthening the substrate.

Requirements for sealing primer: the sealing primer is directly attached to the substrate, which is attached to the middle coat and the top coat, which plays the role of connecting the upper and lower layers, a good coating system has no layer interface between the layers and the layer coating film, the coating construction requires effective mutual penetration between each process, the whole coating becomes a whole, the sealing primer is the first film attached to the substrate, so the quality requirements of the sealing primer are very high, there is good water resistance, alkali resistance, waterproof isolation saline-alkali exudation, good adhesion and interlayer adhesion.

Sealing primer types and raw material selection: there are two types of sealing primers: solvent and water-based, solvent-based sealing primers have strong penetration and strong sealing, and water-based water-based emulsion and water-soluble. The sealing primer of water emulsion and silica sol combination has the sealing performance of solvent-based and emulsion. According to.

The type and condition of the substrate are closed adhesive binders, the loose porous substrate is selected with strong penetration and strong closure to reinforce the substrate, and the dense and smooth substrate is selected with strong adhesive properties and requires good interlayer adhesion.

The main function of the sealing primer is to play a barrier function, so that the plate does not swell and is not easy to come out of the grease of linolinate, which affects the yellowing of the paint film;

The primer is the first layer of the paint system, which is used to improve the adhesion of the topcoat, increase the fullness of the topcoat, provide alkali resistance, provide anti-corrosion function, etc., and at the same time can ensure the uniform absorption of the topcoat, so that the paint system can play its best effect. It plays a role in improving the hiding power and increasing the thickness of the paint film.

Hello Sealing Primer? It should be an isolation primer, or an epoxy primer. The ordinary one is divided into two kinds of primers, one 1k can only cover simple small scratches and very small trachoma, and 2k can cover slightly larger scratches and trachoma, and after sanding, the paint sprayed on it is smoother and more delicate.

Epoxy primer has an extra role in isolating the old paint surface and the new paint surface in the role of 2K primer, and more importantly, it can be attached to the iron sheet (ordinary paint can't do it).

Sealing effect: anti-alkali, anti-salting out, balance the water absorption capacity of the ground, ensure that the color, gloss and light sense of the paint film after construction are uniform and uniform.

Reinforcement: Some foundation ground has loose density and aging of the paint layer, and the coating of the closed primer can make the concrete and terrazzo material ground with good permeability quickly absorb, magically reinforced, prolong the life, and minimize the weakness caused by the aging and looseness.

Improve the adhesion of the topcoat: balance the absorption capacity of the surface coat to meet the maximum needs of customers from the four aspects of topcoat gloss, color, decorative effect and service life.
