Organoclay use for Industrial paint with good thixotropy

The application of organic bentonite in industrial paints has significant features and advantages, including: enhancement of rheology, adhesion, hangability and leveling as well as reducing the cost of production.

First, the main role

1. Thickening rheological additives: organic bentonite in paint can effectively improve the viscoelasticity of the paint, so that it has better rheological properties.

At the same time, it can also be used as a thickener to increase the consistency of the paint, improve the suspension and dispersion of the paint, so as to avoid the problem of pigment delamination and precipitation.

1. Improve adhesion: Organic bentonite has a small particle size, which can effectively improve the adhesion of paint and enhance the bond between the coating and the substrate.
2. improve storage stability: organic bentonite can improve the suspension stability of the paint, especially in solvent-based coatings, can form anti-sedimentation hydrogen bonding, effectively extending the storage period of the paint.
3. improve the film’s anti-sagging: the use of organic bentonite can improve the film’s anti-sagging, making the painting effect more uniform, better texture.
4. can improve the overall formulation of thixotropy. The addition of organic bentonite, so that the thixotropy of industrial paints has been improved.
5. Enhance water resistance and abrasion resistance: organic bentonite as a toughening agent, can enhance the strength and toughness of the paint film, improve the water resistance and abrasion resistance of the paint, the addition of organic bentonite can improve the water resistance and chemical resistance of the paint.
6. Improve leveling: Organic bentonite can improve the leveling of paint, making the coating more uniform in the construction, reducing brush marks and rolling marks.
7. Enhance mechanical strength: Organic bentonite can improve the mechanical strength of the paint, increase the abrasion and scratch resistance of the coating.
8. Reduce costs: due to the covering power and adhesive force of organic bentonite, its addition to the paint can reduce the amount of paint, thus reducing the cost of paint.
9. For example, in the waterproof coating, the use of organic bentonite and asphalt made of paint, can reduce the cost of about forty percent of the project.

Organoclay use for Industrial paint with good thixotropy

The amount of organic bentonite used is different for different types of industrial paints. The following is our respective elaboration:

Organic bentonite in industrial paints mainly play the role of suspending agent and thickening agent Usually the dosage is 0.1% to 5% of the total formula.

It can form a stable suspension system in the paint, enhance the stability of the paint and coating properties. At the same time, it increases the consistency of the paint and improves the workability.

In waterborne paints, the amount of organobentonite is usually between 0.5% and 7%, aiming to improve the leveling of the paint and increase adhesion.

Organic bentonite should be added between 3% and 5%, which is the range after many tests and adjustments to ensure that the performance and quality of the paint.

Conductive paints or antistatic paints, the recommended dosage may be 5% to 10% or higher. Even higher amounts of organobentonite are required to fulfill specific functions.

In high-temperature paints, which are subjected to higher baking temperatures, the amount of organobentonite may be appropriately reduced, and our recommended dosage may be between 0.1% and 2%.

In oil-based paints, on the other hand, the amount of Organic Bentonite is usually between 8% and 10% to increase the thixotropy and reduce the fluidity of the coating.

In addition to the type of paint, the dosage of organobentonite is also influenced by other factors, such as the type of bentonite, particle size and activator. Therefore, it needs to be adjusted and optimized according to the specific situation in the actual application.
