Unlike smooth matte coatings that lack texture or overly coarse finishes that feel harsh, sand grain matte strikes a perfect balance—offering a comfortable, grippy tactile experience while exuding an understated elegance that avoids harsh reflections.

Technically, sand grain matte boasts impressive performance metrics that underpin its reliability. It cures efficiently under flexible conditions: typically 180°C for 15-20 minutes or 200°C for 8-12 minutes (measured by object temperature), forming a dense, cross-linked film with a recommended thickness of 60-80μm. The cured coating achieves Grade 0 adhesion (per GB/T 9286), ensuring a tight bond with metal substrates (steel, aluminum, galvanized metal) that prevents peeling or chipping. It exhibits excellent mechanical strength, with impact resistance of ≥50 Kg·cm (per GB/T 1732) and scratch resistance (pencil hardness ≥H), enabling it to withstand daily wear and accidental impacts. For outdoor use, it offers superior weatherability, resisting UV radiation for over 800 hours of artificial weathering (per GB/T 1865) and withstanding 500 hours of salt spray exposure (per GB/T 1771) without corrosion or texture loss, ensuring long-term performance in diverse climates.

Applied via electrostatic spraying, a method that ensures even coverage even on complex metal shapes (curved railings, intricate furniture frames, or decorative sculptures), sand grain matte is suitable for projects of all scales. Backed by professional technical support, it can be fine-tuned to adjust the coarseness of the sand texture (from fine to medium grain) and the depth of the matte finish, allowing seamless integration with any design vision while preserving its core performance advantages.
