Blend the first components, then add to "Picco" 6070-3 under high shear agitation. Add the water and clay slowly to obtain a uniform dispersion. Add the "Agerite" spar, then reduce the agitation while adding the "Marmix" 22332 and natural latex. The "Ultrawet" DS is added to the natural latex before addition to the compound. The "Acrysol" is added to increase the viscosity. Alternately, "Alcogum" 6625 may be used.
