Unveiling the Innovative NEW VIVILLOY® Material

The automotive industry is witnessing a significant shift towards sustainable practices, with a growing demand for unpainted materials due to cost reduction and carbon neutrality goals. Techno UMG Co., in collaboration with Konica Minolta Japan, recently conducted a series of quantitative analyses using spectrophotometers to validate the performance of their new material, NEW VIVILLOY®. This innovative product aims to provide a high-end black appearance for unpainted automotive exterior components while substantially reducing color variation based on viewing angles.

The Need for Unpainted High-Quality Materials

With increasing pressure to minimize painting processes in manufacturing, particularly in the automotive sector, the challenges associated with unpainted resin materials have become more apparent. Many existing unpainted options display a whitish tint from certain angles and fail to exhibit the desired depth of black color. Therefore, Techno UMG has dedicated its efforts to developing a material that meets the aesthetic demands of luxury automotive design—introducing NEW VIVILLOY®.

Features of NEW VIVILLOY®

NEW VIVILLOY® boasts several remarkable characteristics:

• - Achieves excellent blackness and luster without the need for paint.
• - Significantly reduces angle-dependent color variation.
• - Omits the painting process, contributing to cost savings and lower CO₂ emissions.
• - Balances high levels of color retention, weather resistance, formability, and scratch resistance.

Evaluation Methodology

In the evaluation process, a series of spectrophotometers were employed to assess the new material. Several key criteria were analyzed:

• - Material Color (Reflectance)
• - Apparent Color (Diffuse Reflectance / Specular Reflectance)
• - Angle Dependence at multiple positions
• - Blackness, Jetness, and Undertone

This comprehensive assessment provided a nuanced understanding of NEW VIVILLOY®'s performance compared to existing surface finish options, including traditional unpainted materials and ASA with clear coating.

Outstanding Evaluation Results

The results highlighted NEW VIVILLOY®'s superior performance in several areas:

• - It emerged as the darkest option in both material and apparent color among the compared samples.
• - Demonstrated a significant reduction in angle dependency compared to existing unpainted materials.
• - Outperformed the ASA with clear coat option in terms of depth of black and minimal color change.
• - Regardless of observation angle, NEW VIVILLOY® maintained high levels of blackness, while minimizing blue and red undertones.

These findings indicate that NEW VIVILLOY® not only meets but potentially exceeds the visual quality standards required for high-end automotive components, all without the need for paint.

Future Initiatives

Moving forward, Techno UMG aims to continue proposing unpainted components utilizing NEW VIVILLOY® to offer material solutions that marry aesthetic appeal with environmental considerations. Their commitment to advancing unpainted materials that meet design and performance criteria is unwavering, positioning them at the forefront of the automotive materials industry.

For more detailed information, interested parties can access documentation via the company's website, showcasing the capabilities of NEW VIVILLOY® in their online exhibition. This exhibit also hosts opportunities for downloading material specifications and further exploring the implications of adopting this innovative solution in the automotive sector.
