Based on proprietary PPG resin and pigment technologies, Velvecron SR coating is a clear, two-component urethane topcoat designed for application to primed white plastic and mixed metal substrates. It offers exceptional resistance to staining caused by daily exposure to foods, oils, liquids and lotions, while imparting a luxurious velvety feel to mobile device housings and keypads.
Eric Lama, PPG business manager, electronic materials, Americas, said Velvecron SR coating is a major achievement because it is the first coating to meet this long-standing industry demand. “Leading consumer electronics companies have introduced white-colored tablets, e-readers and electronic devices in the past, but none could provide the long-term stain-resistance consumers want together with the tactile appeal they’ve come to expect from conventional soft-touch coatings.
“White-colored electronic devices are considered premium products and are in great demand around the world, particularly in China – the world’s largest and fastest-growing consumer electronics market,” he added. “This product has the potential to shift the entire worldview about what is possible with electronics design and durability.”
Velvecron SR coating has been successfully trialed by a well-known global consumer electronics manufacturer and will be highlighted in a major device rollout by the company in 2016 focusing on the product’s white color. The coating exceeds industry benchmarks for durability and stain resistance, and it can be sprayed over white basecoats at thicknesses of 20 to 25 microns – less than half the film-build needed with conventional soft-touch coatings. This can help manufacturers reduce material costs and accelerate curing to curb energy use and improve throughput.
Velvecron SR coating also is more flexible than hard ultraviolet-cure (UV-cure) coatings, so devices protected by the material withstand harsh drop tests more effectively than do those finished with competing materials.
As a stain-resistant clear coat, the technology featured in Velvecron SR coating has potential for broad application in markets such as athletic equipment, appliances, automotive parts and accessories, game consoles, furniture, and display products.
