After years of research spanning nano-coating to PU polymer coating to resolve the critical issue of string rusting,
Road Dog rolled out the industry-leading PVD ionic coating process in 2020. Under vacuum conditions, physical
processing vaporizes raw materials into gaseous molecules, atoms and ions that settle evenly on string surfaces
to form a dense protective film. In addition, proprietary trace element blends are incorporated into base materials,
greatly enhancing the strings’ playability and tonality: the finished strings feel smoother during play, retain stable
tone longer and enjoy a markedly extended service lifespan.
Two mainstream coating techniques dominate the current market: US-style wrapped coating and Chinese lacquer
coating. US wrapped coating delivers an ultra-smooth finish preferred by some musicians, yet many players
dislike its excessive slipperiness; its primary downside is diminished natural tonal warmth. Chinese lacquer
coating stands out for its cost efficiency, yet it provides inadequate anti-corrosion protection and wears out
quickly.
Developed by Road Dog, our proprietary PVD ionic coating boosts corrosion resistance and service life to
outperform both conventional coating methods. Meanwhile, we have fine-tuned surface smoothness to elevate
players’ overall playing experience. This revolutionary coating innovation pioneers a brand-new chapter within
string-coating technology and the broader string manufacturing industry.
Road Dog firmly believes no craft is inherently simple; only with genuine craftsmanship can ordinary work achieve outstanding professional quality.
