About Sunmight Abrasives

When professionals in automotive refinishing, marine, aerospace, and metalworking need abrasives they can count on, Sunmight is a name that consistently comes up. The brand traces its roots to Sun Abrasives Co. Ltd, which was established in 1961 in South Korea with a singular mission: to push the coated abrasive industry forward by delivering the highest-quality products to a global market. Decades of research, manufacturing investment, and a genuine commitment to innovation have made Sunmight one of the most recognized names in precision abrasives worldwide.

In the Americas, the brand operates through Sunmight USA Corporation, headquartered in La Mirada, California. Operating from a well-stocked 35,000-square-foot warehouse, Sunmight USA serves customers across the United States, Canada, Mexico, the Caribbean, and Central and South America — ensuring that professional-grade abrasives are never far from reach. The company holds ISO 9001 certification, reflecting a rigorous quality management system that underpins every product it ships.

What Sets Sunmight Apart

Sunmight's product lineup spans coated abrasives in cloth, paper, and film formats, engineered to tackle the most demanding sanding and finishing tasks. Whether the job calls for aggressive stock removal or ultra-fine finishing, the brand offers solutions built around consistent grain distribution, durable backing materials, and specialized resin bonds. Their film-backed products, for example, feature a strong, tear-resistant construction that excels on edges, corners, and irregular surfaces — a detail that matters enormously in body shop and aerospace applications.

Beyond raw materials, Sunmight invests heavily in ongoing research and development, regularly introducing new product series to address evolving industry needs. The result is a catalog that professional finishers, body technicians, woodworkers, and fabricators can rely on across a remarkably wide range of substrates and applications.

Sunmight's Core Product Categories

The heart of the Sunmight lineup is its Sanding Discs — available in hook-and-loop, PSA, and film configurations across a broad grit range, making them the go-to choice for DA sanding in auto body shops and finishing operations of all kinds. For machine-fed and stationary power tools, Sunmight's Sanding Belts deliver the consistent cut and long service life that production environments demand. When hand-sanding or sheet-fed work is the task at hand, Sandpaper from Sunmight offers the same premium grain quality in a flexible, easy-to-use format suited for everything from featheredging to fine finishing.

Surface preparation before painting or coating often calls for something gentler than abrasive grit — that's where Sunmight's Scuff Pads shine, providing controlled surface scuffing without excessive material removal. Rounding out the lineup, Abrasive Cartridge Rolls give technicians and fabricators precise control in tight spaces, port work, and contoured surface finishing where standard discs simply can't reach.

Across every format and grit, Sunmight abrasives are engineered to reduce operator fatigue, maximize cut rate, and deliver a finish quality that meets the expectations of professionals working in the most detail-sensitive industries on the planet.
