1. Hydration speed solution

The hydration speed of magnesium aluminum silicate in water has a great influence on the properties of coating products, such as storage performance and construction performance. The hydration speed determines the state of coating preparation, including fluidity, viscosity and post thickening. For different products with different hydration speed, different methods can be used: pre gelation and direct addition. Products with slow hydration speed can be prepared into pre gel first, so that magnesium silicate thickening agent can be completely hydrated in water before mixing slurry with other additives. For some products with high hydration speed, they can be added in the form of powder and other additives, and can be completely dispersed at last. No pre gel is required.

The product with slow hydration rate, after mixing for a certain period of time, has low viscosity and is convenient for the formulation and completion of the formulation. After the formulation is finished, the product has stable performance at the later stage; the product with high hydration speed can be thickened in a short time, and the process of preparing pre gel is saved.

The company can provide magnesium aluminum silicate products of different hydration levels according to the needs of customers.


2. Thixotropic solution

In the coating construction, in order to obtain a smooth coating with high quality appearance, it is necessary to maintain sufficient levelness in the process of coating application or coating drying and curing, so as to reduce the occurrence of irregular surface of the coating and avoid the occurrence of sagging, which requires the coating to have thixotropy. The addition of sandgel products can make the paint thixotropic, and ensure that the paint has enough low viscosity when in use, so as to carry out full leveling, so as to eliminate the surface irregularities of the paint surface. After construction, it can recover to a certain viscosity, so as to avoid the occurrence of sagging defects.

3. Stability Solutions

Coating stability usually refers to whether the viscosity of the coating changes, whether the pigment settles, whether the water is separated, whether the density of the system is uniform, whether the paint deteriorates, etc. If the above performance is tested according to the national standard, and its change is within a certain range, it can be considered as stable performance.

Sandgel products of our company are inorganic thickeners and rheological agents, which are widely used in coatings. Its thickening effect and suspension are significant, and it can make the paint thixotropic, and the film fullness can be improved after the paint is dried. Sandgel raw material is inorganic silicate clay, which has natural mildew resistance; after the product is dispersed in water, it can quickly establish a "three-dimensional grid" structure, separate and wrap the dispersed phase in the system, stabilize the suspended dispersed phase, and form a thixotropic system with a certain viscosity. Sandgel product has better anti electrolyte ability than organic macromolecular thickener, and maintains stable viscosity within a certain range to prevent gel structure from being damaged and water evolution.

The company can provide professional stability solutions according to the needs of customers to solve problems such as paint water evolution and sedimentation.
