In various industrial frameworks encompassing biofluids, polymers and coatings, interpreting viscoelastic characteristics is indispensable for accomplishing regulated mass and heat transmission. The viscoelastic Oldroyd-B material efficiently characterizes such type of materials where reaction kinetics, concentration and temperature fluctuate at the same time. The current analysis considers the magnetically driven viscoelastic Oldroyd-B material over a magnetized moving surface subjected to variable thermal and variable mass features. The Lorentzian force is introduced due to magnetic field consideration while variable thermosolutal conditions are opted because of dual stratification aspects. In addition, mass transmission features chemical reaction effects. Apposite similarity variables are introduced to transfigure governing PDEs (partial differential equations) into nonlinear ODEs (ordinary differential equations) which are computed analytically through homotopy analysis scheme. A comparative assessment with available published outcomes authenticates the accurateness of analytical outcomes. Besides, the outcomes disclose that Hartman number considerably impact the velocity distribution while solutal and thermal fields are strongly affected via varying conductivity and varying diffusivity factors. These outcomes offer indispensable perception into diffusive-thermo control in coating flows.
