Purchase Silica Aggregate (SFJ-CRA) – Superior Filler for Polymer Systems

SFJ-CRA: The Superior silica Aggregate for Polymer-Based Systems

SFJ-CRA is a premium-grade silica aggregate, high-purity quartz aggregate, distinguished by its exceptional sphericity and a proprietary surface coating. Unlike standard angular sands, SFJ-CRA consists of uniformly rounded particles that are specifically engineered to deliver superior performance in demanding polymer-based applications. The surface treatment ensures an unbreakable bond with epoxy, polyurethane, and other resin systems, resulting in unparalleled durability, chemical resistance, and aesthetic appeal.

Key Features & Benefits

• High Sphericity & Rounded Shape: Ensures excellent flow, easy workability, and higher packing density. This leads to a smoother, more uniform, and void-free surface finish.
• Proprietary Surface Coating: Chemically bonds the aggregate to the resin matrix, significantly increasing mechanical strength, impact resistance, and preventing moisture ingress at the interface.
• Exceptional Hardness (7 Mohs): Provides maximum resistance to scratching, abrasion, and heavy wear, making it ideal for high-traffic industrial and commercial flooring.
• Extreme Purity (≥ 99% SiO₂): Guarantees chemical inertness, color consistency, and long-term stability without unwanted reactions or degradation.
• Precisely Graded Sizes: Available in multiple narrow particle size distributions to give formulators precise control over texture, slip resistance, and system thickness.

Primary Applications

• Epoxy & Polyurethane Flooring: The ideal aggregate for broadcast systems, trowel-down mortars, and decorative quartz floors in commercial, industrial, and institutional settings.
• Polymer Concrete & Mortars: Used to create high-strength, chemically resistant overlays, patches, and precast components.
• Sports & Recreational Surfaces: Perfect for tennis courts, walkways, and pool decks, providing a durable, non-slip, and aesthetically pleasing finish.
• Decorative Architectural Finishes: Used in countertops, facade panels, and textured wall systems for a consistent and attractive appearance.
