Drag Reduction Independent testing trials by private and university laboratories repeatedly show Wearlon^® coatings to be excellent for hydrophobicity, drag reduction, slime and mussel release.

Easy to Apply Wearlon^® SpeedCoat-49 is a water based formula that can be rolled or sprayed by any non-professional. Easy clean up with water.

SpeedCoat-49 has no copper or other heavy metals, no biocides and no harmful solvents. Low VOC — so it is safe for both the applicator and the environment.

Wearlon^® coatings are synonymous with superior adhesion. SpeedCoat-49 will adhere to fiberglass, gel coat, wood, carbon fiber, and all metals, including aluminum. All without a primer in normal conditions.

SpeedCoat-49

is the hull coating of choice for
multiple world champion hydroplane racers and
world record holders.

SpeedCoat-49

is a performance class boat bottom coating. World record holders, championship racers and highly specialized US Naval applications illustrate the efficacy and reliability of SpeedCoat-49. Easy application, even by a novice. Just prep the surface and roll it on. Adheres to aluminum without a primer. Perfect for improving speed and efficiency of aluminum pontoon boats.

For Applicators:

SpeedCoat-49 is a waterborne 2-part silicone epoxy. Easy clean up with water.
Can be applied by rolling or spraying. Hydroplane racers roll on SpeedCoat-49 to achieve a "dimpled" surface texture that creates an air boundary layer for higher top speeds. A smoother surface can be achieved by spraying.
SpeedCoat-49 is only 49% solids with one gallon covering 400 ft² @ 2 mils DFT.
No induction time; just mix and apply.
Pot life of one hour; Dry to touch within one hour; Fully cured and ready for use in 3-5 days.
Due to its water based formula, SpeedCoat-49 is non-toxic, safe and not considered a hazardous material. No worries about EPA fines or non-compliance.

For Marinas:

Wearlon^® SpeedCoat-49 remains effective on your customer's hull, even if it is dry-docked or racked.
Protect your employees and your business from heavy EPA fines by using a compliant performance coating.
Offer your customers the same coating technology used by Boeing, Toyota and the US Navy.
Wearlon coatings are non-regulated materials. No special licensing needed to sell or apply. Can be sold retail to DIY customers.
Resists marring and fouling. Easily cleaned.

For the Boater:

SpeedCoat-49 is proven to significantly reduce drag not just in laboratory settings, but in real world environments.
Less drag means higher top speed
Less drag means better fuel economy
Due to its hydrophobicity and low surface energy, SpeedCoat-49 resists fouling like slime, stains, and mussels.
Easily cleaned. Easy to touch up. Lasts for years with normal use.

Fast Boats / Fuel Economy / Foul Resistant

Many marine coatings are available to boat owners. Before you invest a lot of time and money in a marine coating, you may want to try these four simple tests to determine the best undercoating for your boat. A coating that will improve fuel economy, and speed, while being resistant to fouling will be your end result.

Procedure for Preparation of the Test

Obtain a sample or swatch from the manufacturer for testing. If that is not possible, test the liquid coating by first applying a small amount as prescribed by the manufacturer and allow it to cure for at least a week prior to testing. Apply the coating to a small area of your boat or to a piece of aluminum or plastic. The best surface to allow you to see the results is a clear plastic film such as Mylar. After the coating is cured, perform the following tests.

Test #1

Use a small piece of adhesive tape (Scotch tape) and apply it to the coating surface and rub it with you finger. Remove it from the coated surface, and note the ease of removing the tape. Then stick the adhesive side (face-to-face) together and see if material was transferred from the coating to the adhesive. This can be determined by sticking the adhesive side face-to-face together to see if the tape has lost any of its tack or adhesion properties. If lubricants or any coating has been transferred to the tape, this means that the material will eventually end up polluting the water, as well as changing the surface dynamics of the coating.

Test #2

Apply a drop of water to a fresh area of the coating surface and allow standing for 5 to 30 minutes. If the water droplet flattens out after starting out as a bead of water, this coating is inferior because it shows an affinity for water that result in higher drag resistance.


A good hydrophobic coating.	A poor coating.

After wiping off the drop of water if a milky white or colored spot is left behind where the water was applied, the coating will have inferior drag resistance through water. Initially, the boat will appear to go faster in water, but after a few runs the sacrificial lubricant will be lost and water will absorb into the coating, resulting in decreased speed because of the retained water.

Test #3

This test will evaluate hydrophobicity as a function of water drop off angle. The drop off angle is the angle that you need to tilt the coated material before the water runs off. Apply a drop of water to a fresh area of the coating and measure the initial drop off angle, as well as the height of the tilt to cause the water drop to run off. Immerse the coated material in water for at least twenty-four hours. Again, apply a drop of water to the coating and measure any change in the drop off angle. Note the trail of water left behind on the coating when tilted and rate the drop movement as follows:

Rating #1 (the worst): trail of water equals or exceeds the drop width

Rating #2: trail width is slightly less than the drop width

Rating #3: trail width is less than one-half of the drop width

Rating #4: trail width is less than one-quarter of the drop width (and the trail dissipates rapidly)

Rating #5 (the best): no trail is left behind.

Following are the results of different marine coatings as tested by an independent lab. Tests include paraffin wax, Intersleek, Wearlon, fluorinated polyurethanes, fluorinated polysiloxanes, polyamide epoxy, epoxy polysiloxane, polysiloxane/polyurethane, in modifications with molydenum disulfidesCoating Identification

Polysiloxane Polyurethane			32.7	46.0
Epoxy Polysiloxane			36.4	41.2

Test #4

Immerse the coated substrate in water over a period of time, (one to five days should be adequate), and note upon removing from the water how the water sheds off the coating.


Coating on the left is good.	Coating on the right is not good.

Using your fingernail, scratch the coating (when wet and when dry) for evaluation of the coating's abrasion resistance. Repeat test # 1 to see if there is any change in properties after water exposure.

Conclusion

The best coating for reducing drag through water is the one that has the best contact angle with water, has excellent abrasion resistance, and remains hydrophobic while submerged in water. This allows the water to flow off your hull quickly.

These subjective tests by the mariner will quickly give him a heads-up on the best coating that can supply a clean surface (anti-fouling), provide fuel economy, reduce engine strain, and increase speed.
