Bio-Dur 563
FOR APPLICATION ABOVE OR BELOW WATER
BIO-DUR® 563 is based on a unique blend of liquid epoxy polymer and aliphatic polyamine curing agents, which is able to displace water from wet surfaces in order to make a permanent bond. The formulation is solvent-free to ensure safety and maximum technical performance. Kevlar®* fibers are incorporated for reinforcement and viscosity management to achieve high application rates -even underwater!
BIO-DUR® 563 provides permanent protection under the most adverse conditions. The formula is uniquely field-friendly and uses advanced low toxicity ingredients in a high build brushable/rollable product. The sister product BIO-DUR® 561 is available if a higher viscosity; “light paste” consistency is required. All colors including White are available and can be shipped “Non-Regulated” by USDOT, IATA and IMO.
* Kevlar is a trademark of E. I. Dupont de Nemours Co.

SURFACE PREPARATION:
Remove marine biological settlement and corrosion by >5,000 psi water jetting with or without abrasive. Conventional air/abrasive blasting works well at shallow depths however efficiency falls off sharply below, say, 10′. Hand held power tools such as needle guns or grinders can give good results if applied conscientiously in small areas but will be inadequate in large areas. Plan to apply the BIO-DUR® 563 within 45 minutes maximum after surface preparation to minimize rerusting or initial settlement of fouling slime, which interferes with initial adhesion.
Application above water requires similar high pressure water blasting or dry abrasive blasting to yield a firm, granular surface free of loose contamination.
MIXING PROCEDURE:
BIO-DUR® 563 is supplied in 2 gallon kits of 2xl containers each of epoxy base and curing agent. These components are formulated in contrasting colors to facilitate complete mixing. Visible streaks of either component seen during the course of mixing indicate “hotspots” of unmixed components. It is imperative to properly mix the components since unmixed “hotspots” of either base or curing agent will never cure.
Remove equal quantities of base and curing agent from their cans and place them in a clean plastic or steel container. Mixing is accomplished by stirring with a “Jiffy” type mixer in a geared down, (high torque), 1/2″ electric drill. Once mixing begins, there will be about 20 minutes of working time available at 77° F. This time may be extended by keeping the components and mixture cool, rather than leaving it in a hot area.
APPLICATION:
1) Using a stiff brush or roller apply mixed components from a tray aiming for a coverage rate of about 50 sq.ft. per gallon.
2) Apply by heated plural component airless spray using the following equipment setup:
Spray Unit: Graco “King” or similar with heated hoses.
Mix ratio: 1/1 by volume
Fluid pressure: 2,500 psi
Fluid temp: 140° F
Filters: Remove all filters
Tip size: .031″ -.039″ orifice
CURING BEFORE SERVICE:
BIO-DUR® 563 may be immersed in fresh or salt water immediately after application. It will cure to a hard film within about 8 hours and is suitable for traffic after this time. Allow at least three (3) days at 77° F before subjecting to aggressive chemical service from industrial solvents and similar materials.
