<h2>What is Exterior Paint (Cat Eksterior)</h2> Exterior paint (called Cat Eksterior in Indonesian, Exterior Paint in English) is a liquid or powder coating material used on external building facades, walls etc. Its core functions are decoration and physical protection. According to Grand View Research 2023, the global exterior paint market reached USD 32.8 billion, with Asia-Pacific leading at 42% share, and Indonesia, Thailand, China CAGR at 8.3%. **Modern exterior coatings** must resist UV degradation, rain erosion, thermal stress, and pollutants while meeting low-carbon requirements.<h2>Main Product Types and Formulation Features</h2> - **Acrylic Cat Eksterior**: Based on pure acrylic or styrene-acrylic emulsion, accounts for 55% of global sales. Low cost, medium color retention, suitable for temperate to tropical. Typical solid content 38-42%. - **Silicone-acrylic modified coatings**: Grafted with siloxane, water absorption <3%, stain resistance +30%, ideal for humid industrial cities like Jakarta, Bangkok. - **Fluorocarbon coatings (FEVE/PVDF)**: Fluororesin gives strong bonds, 3000h QUV loss <10%, life 15-20 years, but price 3-5x acrylic. - **Elastic exterior paint**: Elongation >200%, covers hairline cracks, for old wall renovation.<h2>Key Performance Metrics and Standards</h2> Professional selection refers to ISO 12944, GB/T 9755: - Weather resistance: After 2000h QUV-B 313, chalking ≤1, gloss retention >80%. - Stain resistance: GB/T 9780, reflectance drop ≤15% qualified, quality silicone-acrylic ≤8%. - Waterproof & breathable: Vapor transmission >50 g/(m²·d) per JG/T 172. - Eco: China Environmental Label VOC ≤50 g/L, French A+ for export.<h2>Systematic Selection Guide</h2> - Climate: Rainy tropics Indonesia, Cambodia prefer **high-elastic algae-resistant Cat Eksterior**; high-temp Thailand choose reflective heat-insulation coating, surface temp -10℃. - Substrate: New concrete cure 28d, pH<10; metal sheet use epoxy primer. - Color: Dark absorbs heat, suggest L>40; computer tinting reduces deviation.<h2>Standard Application and Acceptance</h2> 1. Surface prep: Remove loose, repair, moisture <10%, degrease. 2. Environment: Temp 5-35℃, RH 40-85%, wind <5 m/s. 3. Process: Roll or spray, theoretical coverage 8-10 m²/L (dry 60μm), two coats. 4. Curing: 7d rain-free, 28d full cure adhesion ≥1.0 MPa.<h2>Industry Trends and SEO Content Strategy</h2> 2024 SEA building material search: **Cat Eksterior waterproof**, **exterior paint eco** monthly >1M.
