Unlock Superior Coatings Performance with GESEESIL® A-200 Fumed Silica

The quest for high-performance coatings demands additives that deliver tangible improvements in the final dried film. While many components contribute during application, fumed silica stands out for its profound impact on the crucial dry film properties. Today, we spotlight GESEESIL A-200 from Zhengzhou GESEE New Materials, a premier hydrophilic fumed silica engineered to elevate your coatings.

Why Fumed Silica? The Science Behind the Performance

Produced via flame hydrolysis of silicon tetrachloride, fumed silica like GESEE®SIL A-200 consists of ultra-fine, amorphous silicon dioxide particles. Its power lies in:

• Extremely High Surface Area: Creating a vast network for interaction.
• Nanoscale Particle Size: Allowing integration without compromising clarity.
• Abundant Surface Silanol Groups: Enabling strong hydrogen bonding.

GESEESIL A-200: Transforming Your Dry Film

Here’s how A-200 specifically enhances key dry film characteristics:

• Enhanced Reinforcement & Durability:

  1.Mechanical Strength: A-200 particles act as nano-reinforcements within the polymer matrix. This network significantly improves scratch resistance, hardness, and abrasion resistance, extending the coating's lifespan against wear and tear.

  2.Toughness: By efficiently distributing stress, A-200 helps prevent crack propagation, improving the coating's impact resistance and overall toughness.

• Superior Anti-Settling & Stability (Indirect Dry Film Benefit):

While primarily affecting the liquid state, A-200's superb thickening and anti-settling properties ensure uniform distribution of pigments and fillers during storage and application. This translates directly to a more uniform, consistent dry film with reliable color, opacity, and performance characteristics across the entire surface. No settling means no weak spots.

• Optimized Rheology for Film Formation:

A-200's ability to impart strong thixotropy prevents sagging on vertical surfaces and ensures excellent edge coverage during application. This controlled flow leads to a more uniform film build and minimizes defects, directly contributing to a higher quality, more protective dry film.

• Improved Weathering Resistance:

The reinforcing effect of A-200 helps maintain film integrity under environmental stress. It can contribute to reduced chalking, better resistance to cracking from UV exposure and thermal cycling, and enhanced overall weatherability and gloss retention.

• Potential for Enhanced Barrier Properties:

The fine particles of A-200 can help fill micro-voids within the coating film, potentially creating a more tortuous path for corrosive elements (like water vapor or salts) or oxygen to penetrate. This can improve the corrosion resistance of protective coatings, especially primers.

Why Choose GESEESIL A-200?
