Changfu® LNE33: Adhesion Promoter for Aspartic Polyurea Coatings in High-End Waterproofing & Anti-Corrosion Applications.

As aspartic polyurea coatings are increasingly used in high-end anti-corrosion and waterproofing fields, the focus has shifted from meeting basic performance standards to ensuring interface stability under extreme conditions. Changfu Chemical introduces Changfu^® LNE33 {3-(Triethoxysilyl)propylaspartic acid diethyl ester}—an advanced adhesion promoter designed specifically for aspartic polyurea coatings, making high-performance protection more durable and reliable.

Product Features:

l  Chemical Bonding Adhesion Promoter – After hydrolysis, the silane forms strong bonds with substrate surfaces, significantly reducing adhesion failure risks.

l  Excellent Organic Compatibility – Contains an aspartate ester functional group with natural affinity and reactivity toward aspartic polyurea resins, integrating seamlessly into the curing network.

l  Internal Plasticization & Low Viscosity – The ester group structure ensures good compatibility, improves substrate wetting, and reduces pinholes and shrinkage defects.

Key Benefits:

n  Enhanced Adhesion – Significantly improves adhesion on difficult substrates, creating a strong interface that blocks moisture penetration and prevents edge corrosion and delamination.

n  Process-Simplifying & System-Compatible – Designed for aspartic polyurea systems, it can be added directly without compromising key properties such as weather resistance, non-yellowing, elasticity, and toughness.

n  Eco-Friendly – Aligns with the low-VOC, high-solids advantages of aspartic polyurea coatings, meeting modern industrial environmental requirements.

Application Areas:

1.    High-End Waterproofing & Anti-Corrosion – Suitable for concrete, metal, and other substrates; addresses wet-surface application challenges and ensures long-term adhesion and corrosion resistance.

2.    Renewable Energy – Wind & Solar – Enhances adhesion for wind turbine blade rain-erosion coatings and photovoltaic mounting systems, withstanding sand, salt spray, and UV aging.

3.    High-Weather-Resistance Topcoats – Ensures long-term UV resistance without chalking or peeling.
