Match Surface Chemistry to the Paint System
Acidic Hydroxymethyl Grades
M3005 and M3010 provide 30±1% SiO₂ at pH 3–5 for compatible water-based resin and paint trials.
Near-Neutral Hydroxymethyl Grades
M-T and MX grades provide 30±1% SiO₂, two particle-size options and a published pH range of 7–9.
Reactive Vinyl Grades
VX2505 and VX3010 require formulation-specific evaluation where vinyl groups can participate in compatible reaction systems.
Custom Paint Compatibility
Amino or carboxyl functionalization can be reviewed after the resin chemistry, pH and performance targets are provided.
Information Needed for Water Based Paint Evaluation
Provide the resin dispersion, formulation pH, additives and target coating properties before selecting a surface-modified silica grade.
- Paint system: identify the resin dispersion, coalescent, pigments, fillers and key additives.
- Particle size: select 6–9 nm or 10–15 nm.
- Silica content: confirm the required standard concentration or range.
- pH: select the compatible 2–4, 3–5 or 7–9 grade range.
- Performance targets: provide hardness, adhesion, drying, blocking, abrasion and storage-stability requirements.
- Order details: include trial quantity, annual demand, packaging and destination country.

Packaging Options
Available polyethylene packaging sizes are 25 kg, 250 kg and 1000 kg.
Storage Temperature
Store at 0–40°C and protect from freezing. Temperatures below 0°C can cause irreversible gelation.
Direct Sunlight
Avoid prolonged exposure to direct sunlight during storage and transportation.
Container Closure
Keep containers closed to limit water evaporation and precipitation of solid silica particles.
Colloidal Silica for Water Based Paint Questions
Which colloidal silica grades can be evaluated in water based paint?
Representative options include the hydroxymethyl-functional M, M-T and MX series, plus VX grades for compatible reactive systems.
Why use surface-modified silica in water based paint?
Surface modification can improve compatibility with selected organic resin systems. Actual hardness, drying and stability benefits must be verified in the complete formulation.
Are VX grades suitable for every water based paint?
No. VX grades contain vinyl groups and should only be selected after confirming compatibility and the intended reaction mechanism.
Which compatibility factors should be checked?
Check resin chemistry, pH, ionic components, pigments, fillers, dispersants, rheology modifiers, mixing order and storage stability.
How should colloidal silica for water based paint be stored?
Store it at 0–40°C, prevent freezing and direct sunlight, and keep the container closed.

Applications of Colloidal Silica for Water Based Paint
Surface-modified colloidal silica can be evaluated in compatible water-based paint systems. Match the functional group, particle size and pH to the resin, additives, substrate and cure conditions.
Waterborne Wood Coatings
M and MX grades can be evaluated in compatible waterborne wood-coating formulations.
Waterborne Industrial Coatings
Used in coating trials intended to improve properties such as hardness and drying speed.
Water Based Metal Paint
Selected grades can be tested for hardness, adhesion and drying performance in compatible metal-coating systems.
Reactive Waterborne Systems
VX grades provide vinyl groups that can participate in compatible double-bond reaction systems.
Water Based Protective Paint
Surface-modified grades can be evaluated where abrasion resistance, blocking or surface durability is targeted.
Hybrid Organic-Inorganic Paints
Suitable for development projects combining nanoscale silica with compatible organic matrices.
