Application of titanate coupling agent GR-311W in aqueous coatings
Release Date:
2024-12-18
In water-based coatings, the main purpose of using water-based titanate coupling agent is to enhance the binding force between the pigment, filler and substrate, and improve the water resistance, weather resistance and the tightness of the coating.
Performance optimization and Precautions
1, combined with different systems: the coupling agent is especially suitable for waterborne coatings containing inorganic fillers, but its compatibility with different polymer systems also needs to be adjusted and optimized according to the specific system.
2. Test optimization: In actual use, it is recommended to optimize through a small test to gradually increase or reduce the amount of coupling agent to find the best addition proportion.
3. Avoid excessive addition: Excessive addition of the coupling agent may lead to the instability of other components in the coating formulation, such as viscosity, dispersion or gloss, so appropriate experimental tests should be conducted before use. Typical application field Waterborne industrial coatings, waterborne wood coatings, waterborne architectural coatings, water-based metal protective coatings, waterborne composite coatings with inorganic filler By correctly adding and optimizing the ratio, titanate coupling agents can significantly improve the physical properties and chemical stability of waterborne coatings.
