SS-650L Silica Matting Agent For Ink Paint

What are the treatment methods and effects of Silica Matting Agent?

If the particles are too large, the surface of the paint film will be too rough, affecting the feel and appearance. Choose products with higher

porosity (pore volume). The larger the porosity, the higher the unit weight of powder content will be, and the better the matting performance will

be. The smaller the average particle size of the Matting Agent, the better the transparency, but the corresponding matting power will also decrease.

It should be pointed out that too high a fine powder content will have a negative impact on transparency.

The anti-settling function will be better. As the storage time of the paint increases, the silica matting agent will show stratification and sedimentation

to a certain extent, but this is only for a short time. If the time is too long, it will still settle.

Generally used in varnish, wax-treated matting powder is added to the varnish to prevent sedimentation and hardening, and is well compatible with

solvent-based coating systems, without refloating adhesion problems. On the contrary, it also adds scratch resistance to the paint film. The disadvantage

is that the matting property of wax-treated matting powder is slightly poor, and the light transmittance of the paint film is slightly poor. The untreated one is

cheap and has good matting degree.

If untreated silica is to be applied to coatings, its structuring degree and uniformity of particle size distribution need to have extremely high requirements.

Thanks to our experienced R&D team, our BACOSIL series matting silica can effectively meet such needs and has excellent performance in anti-settling

and matting properties.

The choice of silica matting agent still needs to be determined by the specific performance in its own system. There is no good one, only suitable one.

The influence of particle size on the application performance of silica matting agent

Since silica matting agent has excellent properties, it has become a matting aid widely used in matte coatings. Silicon dioxide is a solid particle. No matter

what manufacturing process it goes through, it cannot be composed of a single particle size, but fluctuates within a certain particle size range and forms

a certain pattern.

Different particle sizes have different probabilities of appearance. The powder has good particle uniformity and good application performance. This paper

studies in detail the influence of the average particle size and distribution of silicon dioxide powder on the application performance of silicon dioxide, which

has certain practical guiding significance for the selection of matting powder in coating production.

Performance study

1. Matting

Weigh a certain amount of main paint, add the prepared Curing Agent, adjust the viscosity to 15-20s with the formula thinner, and then spray it on the wood

board. After the paint film is naturally dry, use a 60° gloss meter to test it.

2. Transparency

Weigh a certain amount of wood varnish, add a small amount of matting powder, disperse it evenly with a high-speed disperser, pour it into a 125mL white

wide-mouth bottle, and observe the transparency with the naked eye.

3. Anti-settling property

Precipitation rate: Add 5% matting powder to butyl acetate, disperse evenly with a disperser, pour into a 125mL white wide-mouth bottle and observe its

sedimentation rate. Storage stability: Place the prepared main paint in a 50℃ oven for 15 days, observe the precipitation volume, and test the hardness of

the precipitate with an ink knife.
