Hydroxyethyl Cellulose * Real stone paint

1. Thickening effect

Real stone paint is a thick paste type paint containing a large amount of solid particles such as natural stone powder. Hydroxyethyl cellulose can significantly increase the viscosity of real stone paint. Its molecular chains will stretch and entangle with each other in water, reducing the fluidity of the real stone paint system. This is very important for the suspension of solid particles such as stone powder in real stone paint.

For example, in some real stone paints containing stone powder of different particle sizes, hydroxyethyl cellulose can prevent the stone powder from settling due to gravity, ensuring that the stone powder can be evenly distributed in the system during storage and use of the real stone paint. In this way, during construction, the color and texture of the real stone paint applied at each place can be consistent, and there will be no uneven color or uneven particle distribution caused by the sedimentation of stone powder.

At the same time, the thickened real stone paint is easier to control during the construction process. When using a spray gun for construction, the appropriate viscosity can make the real stone paint better adhere to the spray gun, and after spraying, it can be evenly attached to the surface of the coated object such as the wall as required, and it will not flow because it is too thin, nor will it be difficult to spray because it is too thick.

2. Improve construction performance

Hydroxyethyl cellulose can adjust the rheology of real stone paint. During the construction of real stone paint, especially during the spraying process, it can make the real stone paint have appropriate shear thinning characteristics. When the real stone paint is subjected to high pressure and shear force in the spray gun, its viscosity will temporarily decrease, so that it can be sprayed out smoothly through the spray gun; after spraying, the shear force disappears and the viscosity will recover, so that the real stone paint can be better attached to the wall surface, and maintain its original particle accumulation state, showing a natural stone texture.

For the scraping construction method, hydroxyethyl cellulose can also make the real stone paint have good operability. It can make the real stone paint have sufficient adhesion on the scraping tool, and it can be spread flat after scraping on the wall, which is convenient for construction personnel to shape the desired texture effect.

3. Water retention performance

It can enhance the water retention performance of real stone paint. In the film formation process of real stone paint, the slow loss of water is very important. Hydroxyethyl cellulose can form a water-retaining film on the surface of real stone paint, slowing down the evaporation of water.

The binder components (such as emulsion) in real stone paint need to be fully functional in a certain moisture environment to make the stone powder and other particles bond together to form a solid coating. If the water evaporates too quickly, the binder may not be able to wrap the stone powder well, resulting in poor adhesion of the coating and easy sanding. The water retention effect of hydroxyethyl cellulose can provide enough time for the binder to complete the bonding process, thereby improving the quality of the real stone paint coating.

4. Improve stability

During the storage of real stone paint, hydroxyethyl cellulose helps maintain the stability of the system. It can prevent the separation of components such as stone powder and emulsion. Its molecular chain can be adsorbed on the surface of stone powder particles, playing a role of steric hindrance, making it difficult for stone powder particles to aggregate, and also preventing emulsion demulsification.

This can extend the shelf life of real stone paint and ensure that the real stone paint can still maintain good performance after being stored for a period of time, such as color, texture and construction performance. There will be no obvious changes.
