The difference between 1K masterbatch and 2K masterbatch

Masterbatch, known as masterbatch or color seed, is a special colorant for new polymer materials, also known as pigment preparations.

Masterbatches are made up of three basic elements, which are pigments or dyes, carriers, and additives. Masterbatch is a highly concentrated pigment that can give a specific color and appearance to a product, and is commonly used in plastics, rubber, coatings, inks and other industries. Masterbatches have good dispersion and are easy to use, which can improve processing efficiency and reduce costs. During processing, only a small amount of the masterbatch needs to be mixed with an uncolored resin to achieve the desired pigment concentration for the design.

1K Masterbatches

1K masterbatch refers to a one-component masterbatch that relies on the volatilization of solvents to solidify the film.

In the automotive refinish paint series, there are 1K plain masterbatches, 1K pearl/silver pink masterbatches, and 1K medium paints (Su Ash). It is required that the coating adhesion, good weather resistance, smooth and smooth, silver powder or pearlescent arrangement is uniform and clear; After being covered with a matching varnish, it has excellent gloss and fairy reflection.

2K Masterbatches

2K masterbatch refers to two-component masterbatch, which is composed of a component curing agent and a component B resin, which can be mixed in a certain proportion to produce a chemical reaction to achieve the effect of curing film formation and drying.

In the automotive refinish paint series, there are 2K plain masterbatches, 2K overprint varnishes, and 2K epoxy primers. It is required to have good fullness and gloss, solid paint film, and good weather resistance.

The difference between 1K masterbatch and 2K masterbatch

1. The nature of the paint is different

1K color paint is a one-component paint, which mainly relies on the volatilization of solvents to cure and form a film; 2K pigment is a two-component paint, composed of a component curing agent and a component B resin, which needs to be mixed in a certain proportion to produce a chemical reaction to achieve the effect of curing film formation and drying.

2. The drying method is different

1K color paint can be dried naturally; 2K base paints can be dried naturally or baked.

3. The hardness effect is different

After the paint film of 1K color paint dries, it must be protected by spraying varnish to enhance hardness and durability; 2K pigment has a high hardness and is generally used to mix plain paint, without spraying varnish.

4. The proportion of blending is different

1K color paint is sprayed directly with thinner, and the mixing ratio is about 1 to 1; 2K pigments need to be mixed with thinner and hardener, in a roughly 2:1 or 1:0 ratio.

5. Different occasions of use

1K color paint mainly plays the role of base color, and is often used in automotive refinish paint series; 2K paints have better film protection and hardness, and are suitable for high-end body coatings.

Color matching ratio of 1K and 2K masterbatches

Masterbatches are divided into plain masterbatches, silver-pink masterbatches, and pearl masterbatches, but the mixing should distinguish between 1K and 2K, that is, 1K masterbatches cannot be mixed with 2K masterbatches. Mix the same type into a variety of colors.

1K masterbatch is a one-component masterbatch, with 1K plain color (pure white, transparent blue, etc.), 1K silver powder (fine flash silver, silver silver, etc.), 1K pearl (white pearl, red pearl, etc.), mainly relying on diluent volatilization and solidification into a film, and the ratio of thinner is generally 1:1, the surface needs to be sprayed with a layer of 2K overprint varnish to protect, and it is generally “color masterbatch + curing agent + diluent” construction when spraying.

2K masterbatch is a two-component masterbatch, generally 2K plain color (black, white, medium yellow, etc.), high gloss, can be used directly as a topcoat, no need to spray varnish, need curing agent to solidify into a film, the ratio is generally 2:1, appropriate amount of thinner.
