Technical Specifications for Paint-Grade HEC
Understanding technical parameters is crucial when selecting hydroxyethyl cellulose for paint formulations. Below are key performance specifications across different viscosity grades:
| Parameter | Low Viscosity Grade | Medium Viscosity Grade | High Viscosity Grade | Testing Standard |
|---|---|---|---|---|
| Viscosity (2% solution) | 300-600 mPa·s | 4,000-6,000 mPa·s | 20,000-25,000 mPa·s | Brookfield LVF |
| Moisture Content (%) | ≤5.0 | ≤5.0 | ≤5.0 | GB/T 2914 |
| Ash Content (%) | ≤5.0 | ≤5.0 | ≤5.0 | GB/T 9285 |
| pH (1% solution) | 6.0-8.5 | 6.0-8.5 | 6.0-8.5 | GB/T 6368 |
| Transmittance (%) | ≥90 | ≥90 | ≥90 | GB/T 1717 |
| Mesh Size (100 mesh passing rate) | ≥99% | ≥99% | ≥99% | GB/T 1713 |
Viscosity-Temperature Performance Relationship
The effectiveness of hydroxyethyl cellulose for paint applications critically depends on its viscosity-temperature relationship. Tangzhi Technology's specialized HEC products demonstrate exceptional temperature stability, maintaining consistent viscosity from 5°C to 50°C – an essential characteristic for paints applied in variable weather conditions.
Our hydroxyethyl cellulose based additives provide shear-thinning rheology that ensures proper flow during application while preventing sagging on vertical surfaces. This balance of properties makes our products ideal for architectural paints where application characteristics directly impact finish quality.
