High-performance oligomers engineered to optimize mechanical properties, curing velocity, and durability across diversiform industrial substrates.
The chemistry of UV-curable oligomers dictates performance parameters like elasticity, chemical resistance, and substrate adhesion.
Polyurethane Acrylates (PUA), commonly classified under urethane acrylates, are among the most versatile oligomers utilized in photopolymerization. They are produced by reacting diisocyanates or polyisocyanates with polyols and hydroxyl-functional acrylates. This unique synthesis path produces a polymer backbone that combines the tough, flexible, and chemical-resistant characteristics of polyurethane with the rapid curing speed of acrylates.
Choosing the right type of polyurethane acrylate is critical for applications demanding high dimensional stability and long-term durability. We segment our production into two major classes of PUA resins:
Characterized by their exceptional resistance to UV-induced degradation and yellowing. Ideal for external coatings, automotive finishes, and nail gels requiring crystal-clear, durable topcoats.
Offering superior mechanical strength, rapid curing speed, and economic feasibility. They are extensively used in interior industrial coatings, wood varnishes, and high-speed printing inks.
By customizing the polyol backbone (polyester, polyether, or polycarbonate) and functionality (from di-functional to hexa-functional), we modify viscosity, elongation, and crosslinking density.
| Resin / Oligomer Class | Flexibility & Elongation | Tensile Strength & Hardness | Non-Yellowing Properties | Curing Kinetics | Adhesion to Difficult Substrates |
|---|---|---|---|---|---|
| Aliphatic Polyurethane Acrylate (PUA) | Excellent (High elongation capabilities) | Medium-High (Adjustable) | Exceptional (Highly stable) | Moderate to Fast | Excellent (Plastic, Glass, Metals) |
| Aromatic Polyurethane Acrylate (PUA) | Good to Moderate | High (Rigid and tough) | Poor (Subject to oxidation) | Fast | Good (Wood, Composite, Board) |
| Epoxy Acrylate | Poor (Typically brittle) | Very High (Hard and scratch-resistant) | Moderate (Prone to yellowing) | Extremely Fast | Excellent on rigid substrates |
| Polyester Acrylate | Moderate | Medium-High | Moderate | Fast | Moderate (Good pigment wetting) |
How global manufacturers employ Polyurethane Acrylates to solve mechanical limits and process constraints.
Wood substrates require coatings that can withstand structural contraction and expansion without cracking. Using a durable aliphatic polyurethane acrylate (such as our 7200-1 series) ensures that furniture varnishes maintain superior scratch resistance while remaining elastic enough to prevent micro-cracking over years of temperature cycling.
For electronic component encapsulation and protective coatings on non-porous metals, curing shrinkage can peel the coating from the substrate. Our low-shrinkage polyurethane acrylate oligomers like the 73008 Low-Shrinkage Resin are designed with specific molecular spacers that relieve stress during photopolymerization, guaranteeing continuous contact and high moisture protection.
Packaging inks must dry instantly under UV-LED stations while complying with strict migration standards. High-reactivity, flexible PUA oligomers allow formulators to craft inks that adhere strongly to flexible polymer films (BOPP, PET) and sustain the dynamic tension of high-speed flexo presses without peeling or losing color depth.
SLA and DLP additive manufacturing require resins with highly controllable cure depths, fast reactivity, and minimal warp. Specialized waterborne and low-viscosity PUA monomers offer rapid cure speeds and high resolution, producing printed parts with robust dimensional stability and high impact toughness.
The chemical sector is undergoing a rapid evolution toward green initiatives and higher efficiency. We stay ahead of these trends.
1. Shift to Zero-VOC & Waterborne Systems: Global environmental regulations (such as REACH in Europe and China's environmental tax policies) are pushing manufacturers to abandon solvent-based coatings. The development of waterborne UV polyurethane acrylates allows users to coat heat-sensitive substrates while eliminating volatile organic compounds completely. This dual benefit of water-dispersion and radiation-curing technologies is revolutionizing wood and plastic coating lines.
2. The Rise of LED-UV Curing Systems: Traditional high-pressure mercury lamps are energy-intensive and produce ozone. LED-UV curing systems, operating at specific wavelengths (typically 365nm or 395nm), offer cool curing, energy efficiency, and instant on/off switches. Consequently, PUA suppliers must synthesize specialized oligomers that exhibit high reactivity and cure response under LED wavelengths, avoiding surface stickiness caused by oxygen inhibition.
3. Bio-Based Polyurethane Acrylate: As carbon-neutral objectives become mandatory for multinational enterprises, sourcing materials derived from renewable resources is key. Modern PUA syntheses are increasingly incorporating bio-derived polyols (such as castor oil or soybean oil derivatives) to substitute petrochemical alternatives, reducing the overall carbon footprint without compromising the high performance of the cured films.
