Roplex SS-521 (Rohm Haas) is an acrylic emulsion with a MFFT of 45°C. It is recommended that the resin is coalesced with 20 % butyl glycol based on polymer solids. If very porous substrates are being coated, butyl glycol acetate may be used, but water resistance could be reduced. Nowadays Primal EP-6050 would be used to replace Roplex SS-521. [Pg.419]
