3 Terms and Definitions
For the purposes of this document, the following terms and definitions apply.
high filler content
filler percentage of inorganic materials greater than 50 % w/w
liquid methacrylic resin
solution of PMMA polymers and copolymers dissolved in MMA.
NOTE Other chemicals may be added to this resin (e.g. thixotropes, colorants, mould release agents), to further develop resin properties
methacrylic dispersion
dispersion produced by mixing inorganic filler(s) with liquid pure methacrylic resin
methacrylic dispersion types
existing methacrylic dispersions used as materials for sanitary appliances
NOTE Methacrylic dispersion types are given in Table 1 .
