To optimize the properties detailed in the , follow these structural handling principles:
is a high-quality, wax-treated, synthetic amorphous silica produced by W.R. Grace & Co. It is a synthetic amorphous silica that acts as a versatile matting agent for a wide array of coating formulations. It is specifically designed for solvent-based coatings and is especially popular in the wood and furniture finishing industry.
Wear a standard particulate mask (N95 or equivalent) and safety goggles to prevent dry skin and eye irritation.
High-speed dissolvers (Cowles dissolvers) are ideal. Peripheral tip speeds of 5 to 10 m/s for 10–15 minutes are typically sufficient to achieve a homogeneous grind rating (Hegman gauge reading) without destroying the particle structure. Syloid Ed 30 Tds Pdf
Syloid ED 30 is a porous, untreated synthetic amorphous silica appearing as a fine white powder. It is engineered specifically for surface coatings to reduce gloss without compromising the clarity, smoothness, or mechanical properties of the film. Unlike some wax-treated matting agents, Syloid ED 30 relies strictly on its precisely controlled particle size distribution and pore volume to scatter light and achieve a matte finish.

Syloid ED 30 TDS PDF is a synthetic amorphous silica powder with a high surface area and pore volume. It is produced through a patented process that involves the hydrolysis of silicon tetrachloride, resulting in a highly pure and consistent product. The "ED" in Syloid ED 30 TDS PDF stands for "highly dispersive," which refers to its exceptional dispersion properties. To optimize the properties detailed in the ,
A1: The base material, synthetic amorphous silica, is generally recognized as safe (GRAS) and is approved for many food-contact applications globally. However, the specific organic treatment and the final coating's formulation will determine its suitability. Always consult the relevant local regulations for your specific use case and review the official product documentation to confirm compliance.
Note: Avoid media mills (sand or ball mills) for the silica dispersion phase unless absolutely necessary, as intense milling destroys the porous structure. Comparison: Untreated vs. Wax-Treated Silicas
In a typical solventborne 2K PU system at 60° gloss, ED 30 achieves 20 GU at 5% addition , whereas a conventional silica requires 7–8%. This reduces rheology impact and cost-in-use. It is specifically designed for solvent-based coatings and
Syloid ED 30 is best added during the grinding or high-speed dispersion step. While it disperses easily, sufficient shear force should be applied to fully activate its matting efficiency.
Synthetic amorphous silica is hydroscopic and tends to absorb moisture and volatile organic compounds from the environment.
The dosage level depends on the desired gloss level, binder system, and coating thickness. Generally, the addition of a Syloid ED 30 TDS PDF will show a matting curve. Typically, a small percentage by weight of the total formula is required.
Extremely low grit level ensures a flawless, speck-free final finish. 2. Core Functional Mechanisms & Benefits High Matting Efficiency The high pore volume (
