For years, spraying PU coating has been the go-to method to improve silicone’s tactile feel and dust resistance, but it comes with well-known limitations.First the coating typically wears off within months.Secondly the application process generates pollutants and it is not suitable for medical or food application. Instead of relying on ink coatings, the UV treatment will create a permanent protective layer on silicone surfaces by UV radiation. The result is a smooth, non-stick, dust-resistant finish that maintains its performance for the product’s entire lifespan. The process is also significantly more environmentally friendly, eliminating VOC emissions from traditional spray operations while being more energy-efficient and time-saving.
This technology not only enhances the feel and durability of silicone parts but also improves scratch resistance, corrosion protection, and anti-static properties. The treated surface maintains consistent smoothness and gloss, delivering a premium user experience that outlasts conventional treatments.OTI will continue to refine this technology and expand its applications across our product portfolio and offer innovative, sustainable solutions to our global partner.
