Reinforced with Kevlar fibers. Highly tolerant of damp surfaces and can be applied underwater. An anticorrosive coating that is used to protect structures above or below the water and especially in the splash zone. Some versions are approved for Service Level 1 nuclear service.
FOR APPLICATION ABOVE OR BELOW WATER
BIO-DUR® 560SW 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® 560SW 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® 561SW 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.

BELOW WATER: Remove marine biological settlement and corrosion by high pressure 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®560SW within 45 minutes maximum after surface preparation to minimize rerusting or initial settlement of fouling slime, which interferes with initial adhesion.
ABOVE WATER: Application above water requires similar high pressure water blasting or dry abrasive blasting to yield a firm, granular surface free of loose contamination. Since there is no problem from resettlement of marine fouling when working above water it is possible to delay application of the BIO-DUR 560SW indefinitely provided fresh contamination of the surface does not occur.
BIO-DUR® 560SW is supplied either in 2, 4 or 10-gallon kits of 2xl, 2×2 or 2×5 gallon containers respectively each of epoxy base and curing agent. These components are formulated in contrasting colors to facilitate complete mixing. “Black” BIO-DUR® 560SW for example is supplied with a jet-black epoxy base and an off-white curing agent which mix together to yield a black mixture, visible streaks of either black or white seen during the course of mixing indicate “hotspots” 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 easily accomplished by stirring with a “Jiffy” type mixer in a geared down, (high torque), ½” electric drill. Once mixing begins there will be about 40 minutes of working time available at 80° F. This time may be extended by keeping the components and mixture cool, rather than leaving it in a hot area.
1) Using a stiff brush or roller apply from a tray of mixed material aiming for a coverage rate of about 50 sq.ft./ gallon.
2) Application by heated plural spray is easy using the following equipment setup:
Graco “King” or similar with heated hoses.

Fluid pressure: 2,500 psi
Fluid temp: 140° F
Filters: Remove all filters
Tip size: .031″ -.039″ orifice
Note: For productivity estimate an application rate of one gallon per minute through a 0.035″ tip at 2,500 psi.
CURING BEFORE SERVICE:
BIO-DUR® 560SW may be immersed in fresh or salt water immediately after application. BIODUR® 560SW is designed and intended for water service at temperatures up to about 120°F. If resistance to severe chemical or higher heat environments is required we recommend either standard BIO-DUR® 560 or BIO-DUR® 561.
