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



EN 15334:2007 (E) 5 3.3 methacrylic dispersion dispersion produced by mixing inorganic filler(s) with liquid pure methacrylic resin 3.4 methacrylic dispersion types existing methacrylic dispersions used as materials for sanitary appliances
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.



EN 15334:2007 (E) 6 Materials with filler made from aluminium trihydrate are exempt from this test. 5.1.1.2 Apparatus Source of heat ensuring the combustion of organic materials. Means of ensuring homogeneity of the dispersion to be tested (this is most important for dispersions with high levels of sedimentation). Spatula for the sample. 5.1.1.3 Sample 2 g to 15 g of dispersion according to the dimensions of particles. 5.1.1.4 Procedure Ensure the sample is representative of the material to be tested. Stir or roll a larger sample of product for a minimum of 1 h to ensure redispersion of the product. Check that the crucible is clean and dry (heat the crucible to red hot to remove any combustible material). Allow to cool. Weigh the crucible (A). Give the product a final stir and then rapidly scoop a spatula full of material into the crucible. Do not wait to drain the material from the spatula as consistency at this time is key to achieving reproducible results. Place the crucible on a scale and reweigh (B). If additional material is required, repeat the final step (final stir of the product). If too much material has been added, dispose of the contents and repeat from step (check crucible is clean and dry). Heat the crucible to red hot and burn off
