Syloid Ed 30 Tds Pdf -

SYLOID® ED 30: High-Efficiency Matting Agent for Coatings SYLOID® ED 30 is a specialized silica matting agent developed by W.R. Grace & Co

4. Key Performance Indicators from TDS

• Appearance: White, fine powder
• Particle Size (Mean): Approximately 4.5 – 5.5 microns (exact values vary by batch, as cited in the TDS)
• Oil Absorption: Very high (typically > 200 g/100g)
• pH (5% slurry): ~6.5 – 7.5
• Specific Gravity: ~2.1 g/cm³

Shear sensitivity

| Issue | TDS Coverage | Practical Implication | |-------|--------------|------------------------| | | Not mentioned | Prolonged high-shear milling (e.g., bead mill) can fracture particles → loss of matting efficiency + increased viscosity. | | Waterborne systems | Listed as suitable | Hydrophilic surface may thicken over time (post-thickening) – requires stabilizers like associative thickeners. | | Yellowing resistance | Absent | Untreated silica is inert → no yellowing. Safe for white/light finishes. | Syloid Ed 30 Tds Pdf

2. Physical and Chemical Characteristics (from TDS)

It is a synthetic amorphous silica characterized by its high porosity and easy dispersibility. Designed as a white, free-flowing powder, it undergoes a special organic wax treatment to provide superior surface properties and gloss control in various coating systems.

SYLOID® ED 30 is generally considered safe for industrial use when handled according to the W.R. Grace Safety Data Sheet (SDS) . As a synthetic amorphous silica, it does not show acute toxicity in aquatic environments and is chemically similar to inorganic soil matter, meaning it does not pose a high risk of biodegradation or chemical degradation.
