Please click on the following video links for interesting Hoowaki technology demonstrations.

Low Tack. The soft polymer sticks to itself easily. However, when molded with a Hoowaki surface it will not stick to itself - no coatings or material reformulation needed.

Superhydrophobic.  The sample on the left was molded using Hoowaki tooling, while the sample on the right has a smooth surface finish.  The superhydrophobic properties of the Hoowaki surface trap a layer of air, which reflects light from above to give a shiny appearance.

Mud phobic.  The sample on the left was molded using Hoowaki tooling, while the sample on the right has a smooth surface finish.  Both samples are dipped in South Carolina mud from outside our lab.  The Hoowaki surface repels the mud to come out clean.

Self cleaning.  The sample on the left was molded using Hoowaki tooling, while the sample on the right has a smooth surface finish.  When water hits the Hoowaki surface, it picks up the sand and rolls away to leave a clean surface.

Nucleation.  Two pieces of stainless steel are submerged in a container of water which is placed on a hot plate and allowed to boil.  The Hoowaki surface on the left encourages nucleated boiling, with many more and smaller bubbles than the smooth surface on the right.  Hoowaki surfaces have been shown to increase boiling heat transfer by two times!

Hydrophilic, oleophilic.  Hoowaki microstructures on stainless steel cause immense wetting of both water and oil, to give superhydrophilicity and superoleophilicity.
