Description

Syloid 63 is a high-purity, synthetic amorphous silica gel widely recognized for its exceptional performance as a desiccant, anti-caking agent, and flow aid. Its primary value lies in its high surface area and controlled pore structure, which provides superior moisture adsorption and physical stability in demanding formulations. This product is essential for manufacturers in the pharmaceutical, food, and industrial chemical sectors who require a reliable, inert, and highly effective processing aid to ensure product quality and shelf life.

Application

• Pharmaceutical Excipient: Used as a glidant and anti-adherent in tablet and capsule formulations to improve powder flow and prevent sticking during compression.
• Food Additive (Anti-caking Agent): Prevents clumping in powdered food products such as spices, seasonings, milk powder, and baking mixes to maintain free-flowing properties.
• Desiccant: Protects moisture-sensitive products during storage and transport by adsorbing ambient water vapor within packaging.
• Chemical Carrier: Acts as an inert support medium for liquid active ingredients, converting them into a free-flowing powder for easier handling and dispersion.
• Catalyst Support: Provides a high-surface-area substrate for catalysts in various chemical synthesis processes.
• Paint & Coating Additive: Functions as a flatting agent and rheology modifier to control gloss and prevent sagging.
• Plastic & Rubber Processing Aid: Enhances processing by reducing tackiness and improving the dispersion of fillers and pigments.
• Personal Care: Used in cosmetics and toiletries as an absorbent, viscosity modifier, and to provide a matte finish.

Quality Control

Our Syloid 63 is manufactured under a strict quality management system. It is tested to meet relevant specifications for its intended applications, including potential compliance with food-grade (FCC) and pharmaceutical (USP/NF, EP) monographs for colloidal silicon dioxide or silica gel where applicable. Certificates of Analysis (COA) documenting key parameters such as assay, loss on drying, and heavy metal content are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent adsorption of atmospheric moisture, which can affect performance.
