Contact angle of adhesive dropped onto a material indicates the materials wettability.
The lower the contact angle, the more wettable is the surface.
TechnoCoat coating procedure on casting die improves wettability by Al or Mg liquid and achieves increasing a better liquid flow, gas release, and adhesion of release agents, and also preventing erosion, scuffing, and heat cracks.
