As exemplary of component (i) is an epoxidized tricyclo decanedimethanol. A renewable epoxy of component (ii) is cardanol epoxy, derived from cashew nut shell oil (CNSL). Optionally, a component (iii) which is any other epoxy from that of (i) and (ii) can be included, such as Bisphenol-A/F diglycidal ether. The blend is characterized by low viscosity, making it amenable to airless spray application, high solids content and excellent solvent resistance and abrasion resistance. ## Claims ### Claim 1 A resin composition comprising: a component (i): an epoxy resin comprising an epoxidized tricyclo decanedimethanol, and a component (ii): an epoxy resin comprising an epoxidized cardanol. ### Claim 2 (depends on 1) The resin composition according to claim 1, further comprising at least one component (iii) which comprises one epoxy resin other than the component (i) and the component (ii). ### Claim 3 (depends on 2) The resin composition according to claim 2, wherein the component (iii) is one selected from the group consisting of epoxidized Bisphenol-A, epoxidized Bisphenol-F, epoxidized Bisphenol B, epoxidized Bisphenol BP, epoxidized Bisphenol E, epoxidized Bisphenol G, epoxidized Bisphenol P, epoxidized Bisphenol PH, epoxidized Bisphenol TMC, epoxidized Bisphenol Z, epoxidized Bisphenol-S, epoxidized Bisphenol-H, epoxidized Bisphenol-C, epoxidized Bisphenol-AF, epoxidized novolac, epoxidized phenol, epoxidized glycidylamine, brominated epoxy resin, epoxidized cyclohexane-1,4-dimethanol, epoxidized decalin-2,6-dimethanol, epoxidized norbornane dimethanol, epoxidized dicyclopentadiene, epoxidized tricyclopentadiene, epoxidized pentacyclopentadecane, epoxidized tricyclodecane dicarbaldehyde, epoxidized pentacyclopentadecane dicarbaldehyde, and combinations thereof. ### Claim 4 (depends on 2) The resin composition according to claim 2, wherein the component (iii) is at least one selected from the group of epoxidized Bisphenol-A, epoxidized Bisphenol F, epoxidized phenol, and combinations thereof. ### Claim 5 (depends on 1) The resin composition according to claim 1, wherein the tricyclo decanedimethanol has the structure of formula (I): ### Claim 6 (depends on 1) The resin composition according to claim 1, wherein the tricyclo decanedimethanol is one selected from the group consisting of 3,8-bis(hydroxymethyl)tricyclo[5.2.1.02-6]decane; 3,9-bis(hydroxymethyl)tricyclo[5.2.1.02-6]decane; 4,8-bis(hydroxymethyl)tricyclo[5.2.1.02-6]decane; 4,9-bis(hydroxymethyl)tricyclo[5.2.1.02-6]decane; 5,8-bis(hydroxymethyl)tricyclo[5.2.1.02-6]decane; 5,9-bis(hydroxymethyl)tricyclo[5.2.1.02-6]decane and combinations thereof. ### Claim 7 (depends on 1) A coating composition comprising the resin composition according to claim 1 and a hardener. ### Claim 8 (depends on 7) The coating composition according to claim 7, wherein the hardener comprises a polyamide, an isophorone diamine, a bisaminomethylcyclohexane, a bis(aminocyclohexyl)methane, a metaxylene diamine, a diaminocyclohexane, a ethylenediamine, a diethylenetriamine, a triethylenetetramine, or a tetraethylenepentamine. ### Claim 9 (depends on 7) The coating composition according to claim 7, which is photo-initiator free. ### Claim 10 (depends on 7) The coating composition according to claim 7, exhibiting a viscosity of at most about 2000 cps. ### Claim 11 (depends on 7) The coating composition according to claim 7, exhibiting a viscosity of at most about 1800 cps. ### Claim 12 (depends on 7) The coating composition according to claim 7, wherein the solids content of the coating composition is in the range of about 90 wt. % to about 99 wt. % based on the total weight of the coating composition. ### Claim 13 (depends on 7) The coating composition according to claim 7, exhibiting a VOC content of at most about 85 g/L. ### Claim 14 (depends on 7) The coating composition of claim 7, exhibiting a VOC content of at most about 70 g/L. ### Claim 15 (depends on 7) An article of manufacture comprising a substrate and a coating formed by curing the coating composition of claim 7. ### Claim 16 (depends on 15) The article of manufacture according to claim 15, wherein the substrate is metals, concrete or wood. ### Claim 17 (depends on 15) The article of manufacture according to claim 15, exhibiting an impact strength of at least of about 500 g/50 cm. ### Claim 18 (depends on 15) The article of manufacture according to claim 15, exhibiting a pencil hardness of at least of H. ### Claim 19 (depends on 15) The article of manufacture according to claim 15, exhibiting a MEK rub test of at least of about 200.
