Interpretation of the GB/T 9755—2024 standard for synthetic resin emulsion wall coatings

The GB/T 9755—2024 standard for "Synthetic Resin Emulsion Wall Coatings", which will be officially implemented on June 1, 2025, merges and replaces the previous GB/T 9755—2014 standard for "Synthetic Resin Emulsion Exterior Wall Coatings" and the GB/T 9756—2018 standard for "Synthetic Resin Emulsion Interior Wall Coatings". It aims to better regulate the building interior and exterior wall coatings market and adapt to the development trend of high-end and multifunctional products.

Introduction to bentonite rheological agent

Rheology modifiers are key components in paint formulations. The rheological properties of waterborne coatings are a complex interplay between viscosity and shear force, determining the production, storage, and application performance of the coatings.

Hygiene control and "MBA" microbial inspection in waterborne coatings factories

To prevent microbial contamination of waterborne coatings, suitable biocides must be selected to provide long-lasting protection for the product. Maintaining high standards of hygiene in the factory is also crucial.

Water-based coating additive - defoamer

Water-based coating defoamers always penetrate the foam system in the form of particles. When the system needs to produce foam for some reason, the defoamer particles in the system immediately destroy the elastic film of the bubbles and inhibit the generation of bubbles.

Water-based coating additive - substrate wetting agent

In practical applications, water-based coatings often exhibit insufficient wetting of the substrate due to their high surface tension and the complex diversity of industrial construction substrates.

Algae-resistant agent that meets green standards

Tert-butyl hydroquinone prevents algae growth by inhibiting algal photosynthesis, achieving a highly effective algaecidal function, making it widely used in exterior wall coatings.
