In an era where public infrastructure, transportation, and architectural facades demand both aesthetic longevity and minimal maintenance, anti-graffiti and easy-clean coatings have become essential. For formulators relying on BYK-SILCLEAN 3700, the quest for a reliable, high-performance, and often more versatile alternative ends with AgeSin® AG-D9302C. This advanced silicone-modified additive is engineered to deliver superior permanent surface effects with significant safety and compatibility benefits, making it the intelligent upgrade for next-generation solvent-based protective coatings.
AgeSin® AG-D9302C is a hydroxyl-functional, silicone-modified polyacrylate solution, designed as a direct and enhanced alternative to BYK-SILCLEAN 3700. It is supplied at 25% active substance in a carefully selected solvent blend of butyl acetate and propylene glycol methyl ether acetate (PMA).

Enhanced Safety Profile: The significantly higher flash point (>100°C vs. 43°C) of AG-D9302C translates to markedly safer storage, handling, and transportation, reducing fire hazard risks.
Optimized Solvent Blend: The use of a butyl acetate/PMA blend can offer broader compatibility with a wider range of resin systems and potentially improve film formation characteristics compared to a single solvent system.
Direct Functional Equivalent: Both additives operate on the same principle—migration to the surface followed by crosslinking via hydroxyl groups—ensuring AG-D9302C is a true drop-in alternative capable of matching and extending the performance profile of 3700.
AgeSin® AG-D9302C is designed to be a versatile workhorse in the formulator's toolkit, encompassing all classic uses of 3700 while delivering robust performance.
Permanent Anti-Graffiti & Anti-Stain: Forms a dense, crosslinked silicone network that prevents the permanent adhesion of spray paints, markers, and oils, allowing for easy removal with mild cleaners.
Excellent Hydrophobicity & Oleophobicity: Imparts a strong lotus leaf effect, causing water and oil to bead up and roll off, promoting self-cleaning and reducing dirt pickup.
Enhanced Substrate Wettability & Flow: Improves the coating's ability to wet difficult substrates and enhance flow and leveling, leading to smoother, more uniform films.
Anti-Blocking & Mar Resistance: Increases surface slip, which improves resistance to blocking when stacked and reduces marring and scratching.
Beyond direct replacement, AG-D9302C's formulation supports:
Improved Intercoat Adhesion Management: While both additives require sanding for recoatability in crosslinking systems, AG-D9302C's solvent blend may offer more predictable behavior in complex multi-layer applications.
Broad Resin Compatibility: Recommended for use in major solvent-based crosslinking systems, including:
Two-component polyurethanes (2K-PU)
Alkyd/Melamine
Polyester/Melamine
Acrylic/Melamine
Acrylic/Epoxy hybrids
Versatile End-Use Applications: Ideal for coatings on public transit vehicles, architectural metal and concrete, street furniture, industrial machinery, signage, and more.
Addition & Incorporation: Can be added neat or pre-diluted at any stage but is most effective when added post-pigmentation with good stirring. No high-shear requirement is typically needed.
Recommended Dosage: 2.5% to 5.0% on total formulation weight. As with any additive, the optimal dose should be determined through ladder testing in your specific system.
Important Note: For maximum performance, it is recommended to evaluate AG-D9302C without other surface additives initially. If additional flow aids are necessary, they should be tested in a secondary stage.
Choosing AG-D9302C is a decision for enhanced performance, safety, and value:
Proven, Safer Alternative: Offers all the benefits of 3700 with a significantly higher flash point, improving workplace safety.
Performance Parity & Potential Enhancement: Directly matches the permanent easy-clean, hydrophobic, and anti-graffiti functionality, with potential for superior compatibility.
Cost-Effectiveness: Provides a reliable route to high-performance formulations, often enabling competitive pricing without compromising quality.
Technical Support: Backed by comprehensive support to ensure successful integration and optimization in your coatings.
