Start with the job, not the gloss number
Clear coats are usually chosen by the work they must survive. A high-gloss show finish, a fleet respray and an insurance repair have different priorities: depth of gloss, speed of cure, and cost per litre respectively. Decide which segment dominates your market before comparing datasheets.
Check the hardener pairing first
A 2K clear coat is only as good as its hardener match. SANHE clear coats are formulated as a system: clear coat : hardener : thinner = 2 : 1 : 0.2–0.3. Buying clear coat and hardener from different manufacturers is the single most common cause of soft film, poor gloss and premature failure.
When you evaluate any supplier, ask which hardener is specified for each clear coat and whether both ship together in one consolidated order.
Solids, VOC and your market's rules
Higher solids generally means more film build and gloss per coat, but also higher VOC. Many markets in Africa, the Middle East, Central Asia and Southeast Asia apply moderate VOC limits that standard export clear coats satisfy comfortably.
SANHE does not publish a single blanket VOC figure, because the applicable limit depends on the destination country and the specific product. If your market sets a numeric limit, tell us the country and product and we will confirm a compliant grade — and for strict European limits we manufacture custom low-VOC formulations to order.
Durability claims worth trusting
Under standard application conditions SANHE clear coats are rated non-yellowing 5+ years with gloss retention 5+ years. Be wary of suppliers who promise more without stating the application conditions; durability claims without conditions are marketing, not specification.
Trial before you commit
Order a trial quantity, spray it over your own basecoat on a test panel, and check gloss, flow, drying time and polishability in your local climate. SANHE supports trial orders and supplies the matching hardener and thinner so your test reflects the real system.
