Abstract:
1. A structural, radically curable resin composition suitable for (re)lining comprising: (a) 30-70 wt.% of resin having (i) a molecular weight Mn between 500 and 3000 and (ii) an acid value between 0 and 30 mg KOH/g resin, and wherein at least 80% of the total amount of resin is vinyl ester resin, (b) 30-70 wt.% of at least one reactive diluent, wherein at least 25% of the reactive diluent is a difunctional diluent having a molecular weight Mn between 200 and 500 and an optional monofunctional diluent having a molecular weight Mn between 100 and 200, (c) 0.00001 -5 wt.% of an initiator, and (d) 0.00001-5 wt.% of an inhibitor, wherein the average molecular weight per reactive unsaturation (WPU) of the components (a) and (b) is equal to or greater than 190 Dalton and that the amount of styrene in the resin composition is less than 5 wt.% based on the total weight of the components (a), (b), (c) and (d), and wherein the resin composition further comprises a monomaleate and/or monofumarate compound.
