NOTE Other chemicals may be added to this resin (e.g. thixotropes, colorants, mould release agents), to further develop resin properties

NOTE Methacrylic dispersion types are given in Table 1. Table 1 - Methacrylic dispersion types Filler type % of filler Application (examples) Comments ATH (Aluminium
tri-hydrate) Around 60 Vanity basins Shower trays Work top surfaces Soft repairable surface Silica Around 60 Kitchen sinks Baths Shower trays
Quartz Around 70 Kitchen sinks, wash basins, shower trays, work top surfaces The functional surface has an higher content of filler than the bulk
Material is purchased either as a resin mixed with filler or as a resin with the filler added by the sanitary appliance manufacturer 4 Characteristics of dispersion The methacrylic dispersion manufacturer shall provide the following information:  resin type (methacrylate esters);  sedimenting /non sedimenting;  filler type;  polymerisation process (UV, redox, thermal, other). 5 Test methods 5.1 Tests on dispersion 5.1.1 Ash content 5.1.1.1 General See EN ISO 3451-1.

(2) Ensure that the dispersion to be tested is fully re-dispersed at (23 ± 1) °C. Pour the dispersion into the dry flask until full and place the glass disc on the top. As when determining the flask volume, ensure there are no air bubbles beneath the glass disc. Remove any excess dispersion on the underside of the disc or on the outside of the flask before weighing (Weight = C grams). Rinse the flask and
