Paintwork in the Age of “Adhesives”: Expanding the Possibilities of Film Decoration for Automotive Exteriors
3D Decorative Hard Coat Film "Lumiart""
This technology enhances the beauty of your decorations for a longer period while significantly reducing CO₂ and VOC (Volatile Organic Compound) emissions.
Approximately 25% of the total CO₂ emissions generated during the automobile manufacturing process are known to come from the “painting process.” Consequently, decorative films that can replace traditional paint are currently drawing significant attention.
Against this backdrop, Aica Kogyo has developed a 3D decorative hard coat film called “Lumiart.” This material delivers exceptional performance as a hard coat and boasts superior post-processing and moldability, completely eliminating the need for an additional UV curing process after molding.
By replacing traditional paintwork with decorative film, you can drastically reduce CO₂ emissions and entirely eliminate the release of VOCs—a major cause of photochemical smog. This allows for sustainable vehicle production that respects both the workplace and the global environment. Leverage Aica’s advanced technology to vastly expand the possibilities of film decoration.
What is Lumiart?
“Lumiart” is the brand name for Aica Kogyo’s line of high-performance film products.
To maximize the performance of advanced UV-curable resins, Aica Kogyo developed optimal coating techniques tailored to each resin type. This high-performance film is manufactured by perfectly optimizing factors such as the base film, coating thickness, and UV exposure conditions.
It is versatile and can be utilized in a wide variety of applications—not only for automotive interiors and exteriors but also for large displays, smartphones, tablet surfaces, and internal touch sensor films.
Key Features of "Lumiart" 3D Hard Coat Film
Innovative Film Decoration Solutions for Mobility at a Glance
Eco-friendly & Safe Workplace
Reduced CO₂ & VOC EmissionsSwitching from spray painting to our product reduces CO₂ emissions by more than half. It produces zero VOC (volatile organic compound) emissions, enabling the production of sustainable, environmentally friendly vehicles.
High Durability & Weather Resistance
Protects Against UV, Wind & RainLeveraging our extensive resin technology for building exteriors, this film withstands extreme conditions like high temperatures, humidity, and gasoline exposure without any yellowing or deterioration.
Shortened Manufacturing Process
Pre-cured Type, No UV NeededAs a pre-cured product, it requires no UV post-processing after molding. This eliminates the need for additional equipment investment, making it both cost-effective and highly efficient to implement.
Easy to Mold Complex Shapes
Exceptional Elongation RatioOur special resin technology provides excellent elasticity during heat molding. It offers up to 3.5x higher elongation for interiors and 2x for exteriors, seamlessly covering complex 3D contours.
Superior Chemical Resistance
Resistant to Sunscreen & GasolineIt prevents interior plastics from melting due to sunscreen or hand cream residue. It also boasts strong resistance to gasoline and oil, which is essential for automotive exterior applications.
Excellent Scratch Repair
Premium Hard Coat PerformanceThe film features high surface hardness. Minor scratches from car washing can be easily repaired using commercially available compounds and waxes, just like traditional paint finishes.
Applicable to Various Materials
Compatible with Metal & ResinBy optimizing the adhesive and bonding layer, this film can be strongly applied to metal, resin, and other traditionally difficult-to-bond substrates, effectively protecting a wide variety of surfaces.
Unique Decorative Designs
Design Freedom Only Film OffersBeyond standard solid, pearl, and metallic finishes, it achieves designs impossible with paint, such as wood grain, high-gloss piano black, and light-shifting geometric patterns.
Applicable Areas
This technology can be applied to all automotive interior and exterior parts that were previously treated with spray paint.
Depending on the curvature and design of the parts, various vacuum or pressure lamination methods can be selected, such as the Film Insert Method or the TOM (Three-dimensional Overlay Method).
Use Cases
Case 01: “We want to stop using harmful spray paint.”
Due to negative impacts on the workplace environment and rising CO₂ emission concerns, there is a growing trend to phase out spray painting. Previously, however, there were no viable alternatives to spray paint for 3D-shaped components. Our 3D decorative hard coat film provides both “high elongation” and “excellent hardness,” allowing it to flawlessly adhere to complex 3D contours while offering durability comparable to spray coatings—all through a significantly greener process.
Case 02: “The defect rate (yield) in our molding process is not improving.”
“After-cure” products, which require UV exposure post-molding, have an uncured hard coat layer during the molding process. This makes them highly susceptible to deformation, and dust or debris can easily get trapped on the surface, leading to lower product yields. Since our products are shipped fully Pre-cured, the hard coat layer is incredibly stable. This ensures easier handling during production, dramatically lowers the defect rate, and boosts overall product yield.
Frequently Asked Questions (FAQ)
A. We offer thicknesses ranging from 75 to 500 microns (μm) to suit various applications. Custom thicknesses are also available upon customer request.
A. No. Because this film needs to be heated and stretched for molding, specialized equipment such as a vacuum forming machine is required.
A. At present, separating and recycling the film is difficult. However, technology aimed at facilitating easy disassembly and recycling is actively under development as part of a joint industry-academia-government project led by NEDO (New Energy and Industrial Technology Development Organization) in Japan.
A. Yes, absolutely. If you let us know your intended use and required specifications, we will prepare the most suitable sample for you. Please feel free to contact us at any time for more details.
