2.2.3
Polyester Matrix Floor Surfacing
**************************************************************************
NOTE: The first set of figures in brackets for
items a., b., c., and e. represents epoxy and
polyester matrix containing more fillers and
extenders and are suitable for most installations.
The second set of figures in brackets represents
high resin content epoxy and polyester matrices and
should be specified only when higher strengths or
increased chemical resistance is required.
Resistance to reagents specified in item q. is
required to withstand cleaning agents and spillage
associated with normal use. Where resistance to
specific chemicals associated with laboratories,
plating shops, etc., is required, these chemical
solutions and concentrations should be added to the
lists. Manufacturer's literature should be checked
to assure that the matrix is capable of resistance
to these chemicals.
