The disclosure relates to a heat curable powder coating composition suitable for being cured at a temperature from 60 to 130&#xb0; C. containing: a thermal initiation system and a resin system, wherein the reactivity of the thermal initiation system is such that the thermal initiation system provides a geltime between 2.5 and 1000 minutes at 60&#xb0; C. in butane diol-dimethacrylate as measured according to DIN 16945 using 1 wt % of the thermal initiation system in 99 wt % of butane dioldimethacrylate, wherein the amount of thermal initiation system is chosen such that when the powder coating composition is applied to a substrate and cured at a temperature of 130&#xb0; C. for 20 minutes.

Heat-curable powder coating composition

The invention relates to a one component heat-curable powder coating composition comprising a resin containing reactive unsaturations and wherein all said reactive unsaturations are carbon carbon double bonds connected directly to an electron withdrawing group, a thermal initiation system comprising a transition metal catalyst and a peroxide, wherein the peroxide is chosen from the group of peroxyesters, mono-peroxycarbonates and mixtures thereof and a co-crosslinker chosen from the group of vinylethers, vinylesters, vinylamides, itaconates, enamines and mixtures thereof.

One component heat-curable powder coating composition

The invention relates to a radiation curable composition comprising radiation curable components wherein at least one component of the radiation curable composition contains a functional group which, when attached to an acrylate group has a calculated Boltzmann average dipole moment of higher than 3.5 Debye. The invention further relates to radiation curable optical fiber coating compositions having a high dielectric constant.

Radiation curable compositions
