Chemflake Special<br />
Product description<br />
Chemflake Special is a high build glass flake reinforced vinyl ester coating, specially designed for high temperature<br />
service.<br />
Recommended use<br />
Steel in aggressive environments. For maximum corrosion and chemical protection also in high temperature<br />
environment. May also be used for protection of aluminium and concrete (special designed systems).<br />
Film thickness and spreading rate<br />
Minimum Maximum Typical<br />
Film thickness, dry mils (µm) 24,0(600) 40,0(1000) 30,0(750)<br />
Film thickness, wet mils (µm) 25,0(625) 42,0(1050) 31,2(780)<br />
Theoretical spreading rate ft²/gl (m²/l) 64(1,6) 38(0,96) 51(1,28)<br />
Comments<br />
The practical spreading rate may vary from the theoretical dependent upon film thickness and the ambient temperature,<br />
ventilation/wind during the application.<br />

Surface preparation<br />
All surfaces should be clean, dry and free from contamination. The surface should be assessed and treated in<br />
accordance with ISO 8504.<br />
Bare steel<br />
Cleanliness: Blast cleaning to min. SSPC-SP10 "Near White Blast" or Sa 2 ½ (ISO 8501 1:2007). Roughness: use<br />
suitable abrasives to achieve Grade Coarse G 3 - 5 mils (75 - 130 µm, Ry5) (ISO 8503-2).<br />
