Kalore GC contains also
inorganic filler, i.e. strontium glass particles (700 nm, 30–33%
by weight), fluoroaluminosilicate glass (700 nm, 20–30% by
weight) and monodispersed silica (nanofiller: 16 nm, 1–5%
by weight) which are dispersed between the prepolymerized fillers. The fluoroaluminosilicate and strontium glasses
used are silanated. The silica surfaces are treated hydrophobically with dimethyl constituents to attract the silica and
matrix to each other and increase their intimate contact. Dimethyl-treated silica is also more stable than silica
treated with methacryloxysilane, resulting in an improved
shelf life with less risk of material softening during storage
