Select by Surface Group, Particle Size and pH
M Series
M3005 and M3010 provide 30±1% SiO₂ at pH 3–5 with particle sizes of 6–9 nm or 10–15 nm.
M-T and MX Series
These 30±1% SiO₂ grades provide the same two particle-size options at pH 7–9.
VX Series
VX2505 and VX3010 provide vinyl surface groups that can participate in further double-bond reactions.
Amino or Carboxyl Groups
Custom surface functionalization can be reviewed after the target group, formulation conditions and order requirements are provided.
Information Needed for Grade Recommendation
Grade selection should begin with the required surface group, followed by particle size, silica concentration and formulation pH.
- Surface group: specify hydroxymethyl, vinyl, amino or carboxyl functionality.
- 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.
- Modification requirements: provide the target functionality, compatibility criteria and test method.
- 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.
Surface Organic Modified Silica Purchasing Questions

Applications of Surface Organic Modified Silica
Surface organic modification improves compatibility between colloidal silica and selected organic systems. Match the functional group, particle size and pH to the resin and formulation before bulk use.
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.
Organic Resin Modification
Hydroxymethyl-modified grades are selected where compatibility with suitable organic resins is required.
Reactive Coating Systems
VX grades provide vinyl groups that can participate in compatible double-bond reaction systems.
Functional Surface Treatments
Custom amino or carboxyl groups can be evaluated for targeted interfacial or surface interactions.
Hybrid Organic-Inorganic Materials
Suitable for development projects combining nanoscale silica with compatible organic matrices.
