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 k. is
required to withstand cleaning agents and spillage
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.
