Hydrophilic Coating

Hydrophobic Coating



Hydrophilic Coating @ @
  Super Hydrophilic Coating Water Contact Angle Less Than 10X

Gelwell's hydrophilic coating technology is applied in the anti-fog coating and slow moving water vehicle lubricious coating.

Anti-fog Coating

The state-of-the-art Gelwell hydrophilic anti-fog coating technology is the result of years of research and proven in the field.@ Tens of thousands dozens of safety lenses sold globally are coated with Gelwell anti-fog coatings every month. @Besides excellent anti-fog capability, Gelwell coatings also offer excellent scratch, impact and chemical resistances. @The coating solutions have low viscosity with long durability and are very stable during operation. @They are easy to operate in various dipping, flow coat, spin and spray coating processes. @The coating has strong binding efficiency on wide range of substrates such as polycarbonate, nylon, acrylate and glass, etc.@ They can be applied on safety goggles, face shields, helmet visors, snow-board visors, etc.@ Gelwell coatings are heat stable and non-yellowing to the substrates.@ They can be electroplated or tinted with beautiful colors to enhance the stylish lenses. @The coated lenses are flexible and non-brittle and can pass both EC and US impact resistance safety codes. @They can be bended during the lens processing steps.@ The Gelwell coatings have excellent optical properties with refraction index higher than 1.51 and the light transmission over 91%. @Gelwell coatings are non-toxic. @The major components of the Gelwell anti-fog/condensation coatings are biocompatible.


Lubricious Coating for Slow Moving Water Vehicles

The slow moving water vehicle lubricious coating reduces water friction around 7 - 14% depends on the size and speed of the water vehicle. @At the laminar flow region (or boat speed less than a few knots), the lubricious coating is excellent in water vehicle speed acceleration and maneuvering. @The coating helps many athletes won awards in the sail boat, water ski and surfing contests in the US, Asia, Australia and New Zealand.

Gelwell's hydrophobic coating technology is applied in the scratch resistant coating, antifouling coating and high speed water vehicle lubricious coating.

Scratch Resistant Coating

Gelwell offers a variety of scratch resistant coating technologies to meet a multitude of applications that are second to none in performance and longevity.@ The dual coating technology with the scratch resistant coating outside and anti-fog/condensation coating inside the lenses/goggles/shields enhances product values tremendously on the coated products. @The scratch resistant coating and anti-fog coating has strong binding with each other. @In other words, one can apply dip coating of scratch resistant coating on both sides of lenses followed by the spraying of anti-fog coating on the inside of the lenses.@ The technology increases the productivity tremendously. @The scratch resistant coating has strong binding efficiency on polycarbonate, nylon, acrylate substrates. @It has refraction index higher than 1.51 with over 91% light transmission.@ It is heat stable and non-yellowing to the substrates. @They can be electroplated or tinted with beautiful colors to enhance the stylish lenses. @The coated lenses are flexible and non-brittle and can pass both EC and US impact resistance safety codes.@ They can be bended during the processing steps.@The coated lenses can also be recycled without darkening the virgin material.

Anti-fouling Coating

The super-hydrophobic antifouling coating technology can be applied to the polycarbonate, nylon, polarized and other plastic substrates.@ They can be used in the self cleaning lenses, visors, goggles, automobile lamps and windshields. @The antifouling coating can be both hydrophobic and lipophobic to prevent fingerprint from depositing on lenses.

Lubricious Coating for High Speed Moving Vehicle

The super-hydrophobic antifouling coating technology can also be applied on the fast moving water vehicle for speed enhancement. @The high water contact angle surface treatment results in faster speed for boats, ships, yachts, torpedoes that travel under water at high turbulent flow regions. @The antifouling coating also prevents sea mollusk and shells from growing on the ship bottom.
