Formulators choose SYLOID® ED 30 for its versatility across different coating technologies. Common uses include:
Before dissecting the TDS, it is crucial to understand the product itself. Syloid ED 30 belongs to Grace’s family of micronized silica gels. Unlike untreated silicas, the "ED" designation stands for "Efficient Defoaming" or, more critically in this context, an optimized pore structure for superior matting efficiency. Syloid Ed 30 Tds Pdf
| Property | Value (Typical) | Technical Implication | |----------|----------------|------------------------| | | 4.5–6.0 µm | Very fine; produces smooth, low-dusting films. Ideal for thin-film applications (e.g., wood topcoats, coil coatings). | | Oil Absorption | ~250–300 g/100g | Extremely high porosity → high matting efficiency. Requires sufficient binder to avoid film integrity loss. | | pH (5% slurry) | 6.5–7.5 | Neutral → compatible with most resin systems, including pH-sensitive waterborne coatings. | | Loss on Drying | ≤ 3% | Low moisture; good for moisture-sensitive isocyanate or silane systems. | | Surface Treatment | None (untreated) | Hydrophilic. Will disperse easily in polar systems but may cause viscosity drift in non-polar media. | Formulators choose SYLOID® ED 30 for its versatility
Specifically designed to maintain high transparency, making it ideal for clear wood finishes. Dispersibility: Unlike untreated silicas, the "ED" designation stands for
