Organoclay for real stone paint
Organoclay for real stone paint ： Organoclay Bentonite is a natural layered silicate mineral, in the application of real stone paint, mainly utilizes the excellent physicochemical properties of bentonite and organic modification to bring specific functions.
Organically modified bentonite in real stone paint is mainly used to improve the rheology and thixotropy of the coating, which is conducive to the uniform dispersion of pigments, enhance the adhesion of the coating, to achieve the effect of anti-settling.

1. Improvement of coating construction performance:
o Modified bentonite can effectively increase the suspension, anti-sagging and leveling of the real stone paint coating, so that the coating is more uniform and delicate in the construction process, thus improving the spraying quality.
o 2. Enhance the anti-cracking performance:
o Organophilic clay bentonite is a kind of binder, with unique sticky adhesive, can effectively bridge the cracks between the coating of the real stone paint cracks between the cracks, enhance the fastness of the coating and anti-cracking properties.
3. As a thickener: o Organoclay for real stone paint can be used as a thickener, the formation of flocculent gel material in water, to improve the viscosity of the real stone paint, so that the coating is easier to construct, and at the same time to increase the consistency of the coating and water resistance. Therefore, organic bentonite is a more ideal thickener for real stone paint.
4. Improve water resistance and adhesion: The molecular groups of Organophilic clay can be combined with the organic binder in the raw material of the real stone paint to promote the combination between the coating and the substrate, improve adhesion and prevent the coating from cracking and peeling.
5. as a stabilizer and rheological additives:
Organo clay Bentonite has widely used as a real stone paint and all kinds of water-based system coatings, to achieve the stabilization of the formulation and rheological properties. Its chemical resistance, so that the real stone paint in the face of a variety of scholastic erosion, but still maintain a stable compatibility.
6. Preparation methods and raw materials:
o Organoclay for real stone paint usually changes its properties by replacing the inorganic cations in the bentonite with organic cations or by using organic amine salts inserted directly between the bentonite layers.
7. High temperature resistance and lubricity:
o Rheology modifier bentonite acts as a high temperature lubricant and also maintains its properties in high or low temperature environments, providing additional protection for the real stone paint.
8. Thixotropy improvement:
through the modification, to promote the formation of high solid content of the real stone paint, improve the thixotropy and durability of the material.
In summary, Rheology modifier bentonite is widely used in the application of real stone paint, not only to improve the performance of the construction of real stone paint, but also to provide more thickening, suspension and thixotropy for its application in various types of construction and renovation fields.
9, Increase the thickness and gloss of the coating:
o The large amount of modified bentonite organic clay can significantly enhance the thickness and gloss of waterborne real stone paint coatings, making the coatings have a better luster and aesthetics.
Application cases of organoclay modified bentonite in real stone paint
A case background
Water-based paint manufacturers in the production process of real stone paint, in order to improve the performance and quality of real stone paint,
try to add an organically modified bentonite as a suspension additive. Through comparative experiments and actual production applications, found that organic modified bentonite in the real stone paint has significant thixotropic advantages.
Second, the application advantages Improve the coating performance:
In the coating process, the addition of organic modified bentonite in the coating of real stone paint after the surface flatness and gloss have been significantly improved.
In the actual construction process, the addition of organically modified bentonite stone paint shows good construction performance.
The spraying degree of atomization is high, the surface of the paint film is uniform, and the colored sand is neatly arranged, which improves the coloring rate and spraying area of the real stone paint.
At the same time, the speed of material discharging from the gun and the smoothness of material discharging from the gun are also improved, which reduces the construction time and material loss.
Color stability improvement:
The use of organic bentonite in real stone paint can improve water resistance and weather resistance.
After a long time of water immersion and sunlight irradiation test, the addition of organic modified bentonite stone paint still maintains good performance status, there is no obvious cracking, peeling or discoloration phenomenon.
Through the above cases can be clearly seen, organic bentonite has significant advantages in the application of real stone paint.
It can not only improve the coating performance, anti-cracking performance and anti-fouling performance of real stone paint, but also improve the construction performance and enhance the suspension and rheology.
Therefore, we recommend that you can consider adding the appropriate amount of organic modified bentonite to improve the overall performance and quality of the real stone paint in the actual production.
