TLDR
In this paper, the authors proposed casting resin suspensions comprising from 40 to 80% by weight of an inorganic filler, from 60 to 20% of a liquid, polymerisable, organic precursor and from 0 to 5 parts by weight, based on the sum of a polymerisable organosilicon compound as adhesion promoter (coupling agent).Abstract:
The invention relates to casting resin suspensions comprising A) from 40 to 80% by weight of an inorganic filler, B) from 60 to 20% by weight of a liquid, polymerisable, organic precursor and C) from 0 to 5 parts by weight, based on the sum of A) and B), of a polymerisable organosilicon compound as adhesion promoter (coupling agent), where the inorganic filler is a mixture of at least two filler particle fractions of different average particle size, and the size ratio between the average particle sizes of the large and small filler particles is between 10 : 1 and 2 : 1, and the weight ratio between the proportions of the large and small filler particles is between 4 : 1 and 1 : 4. The filler particles preferably comprise aluminium hydroxide and/or aluminium oxide hydrate, and component B) preferably comprises at least 50 parts by weight of (meth)acrylates.read more
