Engineered for ultimate adhesion, scratch resistance, low shrinkage, and superior outdoor durability.
An authoritative guide to chemistry, structure-property relationships, and high-durability coating formulation.
Formulated with aliphatic isocyanates (e.g., IPDI, HDI) rather than aromatic structures. This eliminates chromophore groups that cause yellowing under intense UV irradiation, ensuring long-term optical clarity.
By adjusting the oligomer backbone length and acrylate functionality, we tune the cured film properties to strike the perfect balance between high tensile strength, elasticity, impact resistance, and surface hardness.
Specially designed functional acrylic groups ensure excellent interfacial wetting and chemical bonding with problematic substrates, including metals, engineered woods, composite materials, and plastics (ABS, PC).
In high-performance industrial coatings, selecting the correct oligomer structure defines the limits of protection. Below is a structural and comparative matrix of Aliphatic Polyurethane Acrylates (PUA) versus alternative UV-curable oligomer classes:
| Oligomer Type | Weatherability (QUV Test) | Tensile Strength (MPa) | Elongation at Break | Typical Viscosity (cps @ 25°C) | Core Industrial Applications |
|---|---|---|---|---|---|
| Aliphatic PUA (HDI/IPDI Based) | Excellent (>1000 hrs Delta E < 1.5) | 25 - 45 | 15% - 80% | 5,000 - 45,000 | Automotive clearcoats, outdoor signs, optical displays, aircraft skin protection |
| Aromatic PUA (TDI/MDI Based) | Poor (Rapid yellowing) | 30 - 55 | 5% - 40% | 8,000 - 60,000 | Indoor floor finishes, structural adhesives, indoor wood sealants |
| Epoxy Acrylate (Bisphenol A Based) | Poor (Chalks under solar UV) | 40 - 70 | 2% - 10% | 20,000 - 100,000 | Electronic solder masks, paper varnishes, wood primers (high hardness) |
| Polyester Acrylate | Moderate to Good | 10 - 30 | 10% - 50% | 500 - 5,000 | Fast curing lithographic inks, overprint varnishes, low-viscosity primers |
