10,In water borne paints coatings, does rheology modifer have the advantage of thickening fluidity?

Organoclay thickeners can increase the viscosity of coatings and improve the rheological properties of coatings, which are indispensable in the production of coatings.

Each coating has its requirements for rheology. For example, in the storage stage, latex paint should have a higher viscosity to prevent delamination and precipitation;

in the construction stage, latex paint is subject to high shear rate external force, which requires Low viscosity, no drag when brushing, good atomization when spraying, no splashing when rolling. After coating, the shear disappears, and the viscosity recovers but should not be too fast to allow sufficient leveling time. This requires a suitable thickener to change the viscosity of the coating.

As an inorganic thickener, bentonite has a certain degree of application in the production of coatings. Its characteristics are significant thickening effect and suspension, which can make coatings thixotropic, which is convenient for storage and construction.

Rheology modifier in water-based paints is to form a gel and optimize the performance of the paint.

Rheology modifier is an inorganic mineral and organic ammonium compound. It uses bentonite as a raw material. It uses the layered structure of montmorillonite in bentonite and its ability to swell and disperse in water or organic solvents into colloidal clay particles. Through ion exchange Technology is made by inserting organic covering agent.

Rheology modifier can form a gel in various organic solvents, oils, and liquid resins, which can optimize the thickening, thixotropy, suspension stability, high temperature stability, lubricity, film formation, water resistance and chemical stability of coatings. It has important application value in the coating industry. It is also widely used in paint and ink, aviation, metallurgy, chemical fiber, petroleum and other industries.

 How many days can we receive the rheology modifier in our destination port?

Generally, we are able to make our shipments in 5-10days after getting the official order. And it will take about 7-30 days depending on the distance and transportation way to arrive at the final port. These days can show slight variations according to the season and organoclay.

What is the min order amount that we can buy directly from China via vessel?

The total amount should be at least 1MT (one pallet). We are not recommending loading less than one pallet because of rheology modifier safety inside the container. If you need less than 1 MT, it’s better to make the delivery with air cargo.

How many types of packaging methods are there for your  rheology modifier bentonite?

Packing of rheology modifier : 25Kg/Bag,22.68kg (50lb)/Bag, 1MT/bag or 500kg/Bag. Kraft paper bag with PE liner or multi-wall paper sacks or customized.

Camp Shinning is a holder of the ISO
9001 / ISO 2015 certificates, which guarantees that
all productions of rheology modifier are conducted according to the stipulated standards

What kind of solvent should be used for the activation of waterborne paints?

The best polar additives are methanol, ethanol and propylene carbonate

In the production of paints and coatings, there must be no water in the solvent, can it be activated with ethanol?

It can be activated with ethanol.

  Rheology modifier is made by using bentonite as a raw material, using the flaky structure of montmorillonite in bentonite and its ability to swell and disperse into colloidal clay particles in water or organic solvents. It is made by inserting organic covering agents through ion exchange technology. . Organobentonite can form a gel in various organic solvents, oils, and water-based formulations. It has good thickening, thixotropy, suspension stability, high temperature stability, lubricity, film-forming properties, water resistance and chemical stability. , It is also widely used in the coating industry, ink, petroleum and other industries.

In the various stages of coating production and use, the rheological properties of the coating are also important factors that must be considered. Adding an anti-settling agent to the coating means introducing a good thixotropic structure into the coating, which can suspend pigment and filler particles without agglomeration, prevent pigment settling, improve coating performance, and maintain excellent leveling.

Rheology modifier is made of natural montmorillonite (mainly hectorite and bentonite) as raw materials and reacts with quaternary ammonium salts. In coatings, organic bentonite is usually used as an anti-settling agent and thickener. Its mechanism to prevent precipitation is to change the rheological properties of the system to make it thixotropic, thereby preventing the precipitation of pigments and fillers.

Method for adding rheology modifier.

Pre-gel addition and powder addition can be carried out directly according to the situation. In order to give full play to the thickening effect of organoclay, it must first be fully activated by adding polar additives such as methanol or ethanol.

In Rheology modifiers for waterborne paints, the difference between using aqueous methanol and anhydrous methanol?

Using methanol containing water, the viscosity will rise quickly, and the thickening and suspending properties will be particularly good, while the use of anhydrous methanol will not achieve the gel effect.

Other matters needing attention when using water-based organic bentonite:
1) When producing water-based paint, try not to use metal utensils. When grinding, do not use metal utensils, you can choose plastic utensils.
2) When producing water-based paint, do not stir at high speed to avoid the appearance of a lot of cheongsams and demulsification.
3) When producing water-based paints, we must not only choose our high-quality rheology modifier, including the selected pigments and fillers, but also purchase from high-quality suppliers as much as possible to ensure that the quality of the entire formulation is matched and stable.
4) In the production of water-based paints, if you always face dispersion problems, you can also add a certain amount of water, stir at high speed, and then slowly add fillers for medium speed stirring.
