Practical technical articles from our R&D team and the trade shows where you can meet DAHUA Chemical in person.
In solventborne systems the dispersant works almost entirely through steric stabilisation. How anchor groups, solvated chain length and binder interactions decide grinding efficiency, colour development and storage stability.
Read article →ASE and HASE thickeners both rely on alkali neutralisation, but HASE adds hydrophobic association. A comparison of the rheology profiles, application behaviour and formulation trade-offs behind the choice.
Read article →The carrier of a defoamer decides how it arrives at the foam lamella. Comparing emulsion and water-dispersible types with oil-based mineral and silicone carriers on deaeration speed, persistence and crater risk.
Read article →Foam generated during dispersion, let-down and application behaves differently at each stage. A practical framework for matching defoamer chemistry to where the foam actually forms, and how to stay inside the compatibility window.
Read article →Colour strength, grinding efficiency and storage stability pull dispersant selection in different directions. How pigment surface polarity, molecular architecture and dosage on pigment interact in practice.
Read article →Water's high surface tension changes the additive requirements for every function at once. How wetting, defoaming and rheology additives interact, and why solving one problem often creates the next.
Read article →Polyurethane chemistry restricts additive choice more than any other coating system. Moisture sensitivity, hydroxyl and amine functionality, and pot-life effects: what to watch for in 2K PU formulation.
Read article →PVC and polyolefin substrates combine low surface energy with active migration. How coupling agents, adhesion promoters and surface control additives work together on plastics.
