Based on the Technical Data Sheet (TDS), the typical physical and chemical properties include: Appearance White free-flowing powder Average Particle Size 5.0 – 6.0 μm Pore Volume Oil Adsorption 250 – 300 g/100g pH (5% aq. suspension) 6.0 – 8.5 Silica Content ( cap S i cap O sub 2 Carbon Content 6.0 – 9.0% (due to organic treatment) Bulk Density 200 – 600 Key Benefits Superior Matting Efficiency
Because of its high matting efficiency, formulators can achieve the desired low-gloss level with a lower dosage compared to standard silicas. Industrial Applications Syloid Ed 30 Tds Pdf
Used in highly flexible, thin-film synthetic top layers to convert shiny plastics (like PVC or polyurethane) into natural-looking matte leather finishes. 4. Formulation, Incorporation, and Processing Guidelines
I should make sure to explain technical terms for clarity. For example, explaining what BET surface area is, even briefly. Also, mention if it's amorphous silicon dioxide, which is common in diatomaceous earth and important for safety (as crystalline silica can be hazardous, but amorphous is less so).
Formulations containing Syloid® ED 30 exhibit good storage stability, resisting hard settling over time. Any soft settlement can easily be redispersed with mild agitation. 5. Processing and Formulation Guidelines
Excellent for coatings on automotive plastic parts and artificial/natural leather. Advantages and Technical Performance | Property | Value / Specification | Test
The efficacy of Syloid ED 30 relies on its controlled particle size distribution and high pore volume. These characteristics disrupt surface reflection without compromising film clarity. Synthetic Amorphous Silica ( SiO2cap S i cap O sub 2 Appearance: Fine, white, free-flowing powder Average Particle Size ( d50d sub 50 ): 5.0 – 6.0 microns (Coulter Counter) Pore Volume: ~1.2 mL/g Oil Absorption: ~220 g/100g Surface Treatment: Untreated (Non-wax treated) Mechanisms of Matting
Introduce Syloid ED 30 during the post-addition or "let-down" phase of manufacturing. Equipment: Use a standard Cowles-type high-speed dissolver.
Due to its optimized pore volume and particle size, lower addition levels are required to achieve target gloss levels compared to lower-grade silicas.
: Easily dispersible with high shear stability, meaning it resists over-grinding during the formulation process. Sourcing Documentation Grace | IMCD Portugal For the most accurate
: Solvent-borne and water-borne furniture coatings, wood stains, and protective finishes.
oil absorption metric, formulating with high dosages of silica will pull free solvent or water from the matrix, causing a rise in viscosity. Formulators should balance solids, co-solvents, and wetting additives to maintain optimal leveling and air-release properties. 5. Storage, Safety, and Handling Protocols Silica Matting Agent SYLOID ED 30 For Furniture Coatings
In summary, SYLOID® ED 30 is an essential additive for modern formulators who need to balance the visual demand for matte surfaces with the technical requirement for durable, high-clarity protective films. SYLOID ED-30 - W.R. Grace | IMCD Spain
Sylodent ED30 is a specialized grade of diatomaceous earth produced by Cabot Corporation, a leading manufacturer of industrial additives. Derived from the fossilized remains of diatoms (microscopic algae), diatomaceous earth is renowned for its high porosity, low density, and abrasive properties. The ED30 grade is tailored for industrial applications where consistent particle size, high surface area, and specific surface texture are critical. This article delves into the key details outlined in the Sylodent ED30 Technical Data Sheet (TDS) and explores its applications, advantages, and handling guidelines.
