Granulate material and associated coating that is low in odor and emissions, particularly a construction element coating, for example a floor coating, based on a radical polymerization

A granulate material for a radical chain-growth polymerization based coating formulation, the granulate material having an average particle size d50 of between 0.1 and 2 mm, measured according to ASTM C136, is selected from the group consisting of (i) apolar granulate materials having a contact angle with water of 35° or more, when measured according to the norm DIN 55660-2:2011-12, at least partially coated with at least one component C1, which is an accelerator and/or a radical initiator, wherein the amount of component C1 is more than 0.2 g/m2 and less than 5 g/m2 of apolar granulate material surface area, or (ii) granulate materials coated with at least one component C1, which is an accelerator or a radical initiator, wherein the amount of component C1 is more than 4 g/m2 and less than 10 g/m2 and mixtures thereof, wherein, when component C1 is an accelerator, said accelerator is selected from tertiary amines, ammonium salts and mercaptans.
