  28. 28. Conclusions High compatibility was observed of highly refined naphthenic oils with mPO type adhesives The performance of naphthenic oils are similar or better than paraffinics SAFT was similar for both naphthenics and paraffinics Higher wetting and modulus observed for naphthenic oils For most of the formulations naphthenic plasticisers provide additional value such as: High solvency and compatibility Very good flow properties Improved adhesive properties Good creep resistance It is feasible to increase the oil content to 20-25% and decrease the amount of tackifyer resin 2014-04-2928
