HYDROMO’s Hydrophobic Surface

Testing was conducted in the Albert Yee Laboratory at the University of California, Irvine

The HYDROMO’s housing is fabricated using a unique micro topography mimicking the microtexture of a hydrophobic spray.  This topography is molded using a polystyrene polymer which further increases the hydrophobicity of the housing.  The high hydrophobicity of the housing prevents buildup and ensures the prevention of biofilm.

Hydrophobic Testing

Using a super hydrophobic spray on each product can be costly, leads to a high product variability, and  uneven coatings.  Thus Liquidus Diagnostics uses a unique molding protocol that mold a hydrophobic polystyrene housing with hydrophobic micro features. In this study, Liquidus engineers compared typical polyurethane polymers used in toilet products and compared their hydrophobicity to the polystyrene used in the HYDROMO.  Results showed that the HYDROMO is significantly more hydrophobic.  Contact angles greater than 90 degrees are considered hydrophobic.

Microtopography Hydrophobic Test

Tests were conducted on the HYDROMO’s housing with and without a micro texture.  The micro texture significantly increased the hydrophobicity of the tested surfaces.  Contact angles greater than 90 degrees are considered hydrophobic and the final housing has a contact angle mean of 120 degrees.  Thus, the HYDROMO is really hydrophobic; it repels water.
