WB alkyds solutions

• Chose EO/PO alkoxylates, but not optimal• Designed new molecule in required HLB range

– Patented reactive surfactant• Blend nonionic Maxemul 8201 and anionic

Maxemul 7201 (80/20)• Optimize concentration of surfactants (~7%)

Epoxies

• Epoxy emulsions require HLB 16-17• High viscosity, sometimes solid• Atsurf 3969 combines 2 higher HLB
