      PAM is water soluble, but it dissolves very slowly and requires much agitation and time to dissolve. Water containing more than 0.1 percent PAM is noticeably viscous, and most PAMs have a maximum concentration of 0.5 to 1 percent in water. When dry PAM becomes wet, it is very slippery and sticky and can create a slipping hazard.
