Self-drying alkyd anti-settling and anti-sagging additive is an additive specially used for self-drying alkyd paints, which aims to solve the sedimentation and sagging problems that may occur during the construction and curing process of the paint. The following is a detailed analysis of this additive:

1. Definition and function

Definition: Self-drying alkyd anti-settling and anti-sagging additive is a compound that can increase the viscosity of the paint and prevent the pigment from settling and sagging.
Function:
Anti-settling: By controlling the suspension state of the pigment, it prevents the paint from hard precipitation or sedimentation during storage and construction.
Anti-sagging: Increase the viscosity of the paint, so that the paint is not easy to flow during the curing or construction process, and avoid the formation of sagging.

2. Product characteristics

Rheological properties: It has excellent rheological properties and can form a stable suspension system in the paint to prevent pigment sedimentation.
Thixotropy: Some additives such as hydrogenated castor oil system and amide wax system have strong thixotropy, which can change viscosity under shear force to prevent sagging.
Temperature stability: Some additives may lose their effectiveness at high temperatures, but their rheological properties can be restored as the system cools. Therefore, it is necessary to pay attention to the construction environment temperature when using it.

3. Application and precautions

Application:
Applicable to self-drying alkyd paint, which can be used for coating in the fields of automobiles, furniture, construction, etc.
Usually added during the production of the paint or before construction, the specific amount added needs to be adjusted according to the type of paint and construction requirements.
Precautions:
The additives need to be fully stirred before use to ensure that they are evenly dispersed in the paint.
The construction environment temperature and humidity need to be controlled within a certain range to ensure the effectiveness of the additives.
After adding the additives, the paint may need to be aged to improve its construction performance.

Self-drying alkyd anti-settling and anti-sagging additives play an important role in paint construction. By reasonably selecting and using additives, the construction performance of the paint and the appearance quality of the final coating can be significantly improved.
