Paints addtives and its function
- Resin (Acrylic/PVA/Styrene-Acrylic) – Film formation & durability
- Pigments (TiO₂/Colorants) – Color & hiding power
- Water – Primary solvent (VOC-free)
- Functional Additives:
- Dispersants – Stabilize pigments
- Defoamers – Control foam
- Thickeners (HEC/HASE) – Adjust viscosity
- Biocides – Prevent microbial growth
- Coalescents – Improve film formation
- pH Adjusters – Stabilize formulation (pH 8-9)
- Fillers (CaCO₃/Talc/Kaolin) – Cost optimization & reinforcement
Dry mixed mortar addtives and its function
1.HPMC/HEMC（Water Retention Agents）
