HYDROCOTE 3061|

Marine epoxy paste adhesive

DESCRIPTION:

HYDROCOTE 3061I two-component, epoxy paste adhesive is designed to be applied to surfaces and pumped into deep voids and cracks above and below the waterline.

RECOMMENDED FOR:

  • Patching spalls
  • Bonding and anchoring to concrete, steel and other rigid materials
  • Coating for steel to prevent corrosion
  • Pumping into voids and joints Sealing seams in FRP jackets and forms (Used with A-P-E Process as seam and gasket adhesive)
  • Surface seal for crack injection

FEATURES/BENEFITS:

  • Can be glove applied, hand troweled or pumped by two component system
  • Adheres to prepared surfaces underwater
  • Cures down to 40° F (4° C)

PACKAGING/ESTIMATING:

HYDROCOTE 3061I epoxy paste adhesive is packaged in 2 US gallon (7.6L) units

Coverage Rates

1/16 in. (1.5 mm) 51.2 ft2/2 gallon unit (2.38 m2/L)

1/8 in. (3 mm) 25.6 ft2/2 gallon unit (1.18 m2/L)

SURFACE PREPARATION:

Concrete Surfaces - New concrete must be fully cured (28 day min.) before application of HYDROCOTE 3061I epoxy paste adhesive.

The substrate must be clean and sound. Remove all marine growth, pain, grease, oil or other contaminants by sandblasting, waterblasting or rotary abrading. Create an anchor profile, if possible.

Steel Surfaces - Steel surfaces must be cleaned to meet SSPC-SP6-63, "No. 6 Commercial Blast Cleaning."

Wood Surfaces - Remove all marine growth, paint, grease, oil and other contaminants by sandblasting, waterblasting or rotary abrading. Remove unsound wood.

MIXING:

Hand Mixing - Mix only the amount of paste that can be placed within the specified pot life. (Higher temperatures shorten pot life). Place equal parts of A and B on a flat disposable palette (i.e. sheet of cardboard) and mix with a flat bladed scraper or trowel. Mix until all evidence of the original white and black colors have disappeared and a uniform gray color is achieved. Mixed paste may be placed into disposable cartridges for use with hand or powered caulking tools.

Mechanical Mixing - If plural component equipment is used to mix and place HYDROCOTE 3061I epoxy paste adhesive, place equal amounts of A and B in the appropriate hoppers of the equipment. If placement is delayed for periods greater than 10 minutes, purge the static mixer or replace the mixer element, if necessary.

APPLICATION:

When applied to surfaces under the waterline, it is necessary to “work” the paste on to the surface, being careful not to entrap water between the paste and the surface. When used to cover cracks, work paste into one end of crack and progress along crack to other end, displacing water from the crack. Smooth outer surface with glove or trowel.

When used to anchor embedded items, spread evenly over surface of embedded item and inject additional paste into cavity. Use caulking tool or plural component equipment with sufficient nozzle length to reach base of cavity. Push embedded item into cavity, displacing any water or air in cavity and completely fill cavity with paste. Smooth outer surface of paste with glove or trowel. If outer surface is vertical, it may be necessary to provide a temporary dam of plumber’s putty or other support, to prevent the paste from sagging.

Supported Paste - HYDROCOTE 3061I epoxy paste adhesive may be applied to surfaces under the waterline, using a fabric support. The paste is spread onto glass fiber mat or mesh to provide a film thickness of 1/8 to 1/4 in. (3 mm to 6 mm). The coated fabric is worked against the surface, with care taken to prevent entrapment of water or air bubbles between the surface and the fabric. Some of the paste must be forced through the fabric to thoroughly embed the fabric. Additional paste may be applied to the outside of the fabric, if necessary. Smooth the outside surface of the paste and feather edges with a gloved hand.

CLEAN UP:

Mixed epoxy is much easier to clean up before it hardens. Solvents, such as acetone, methyl ethyl ketone (MEK) or toluene may be used. Commercial epoxy strippers are recommended for hardened epoxy. Consult solvent manufacturer’s usage recommendations.

SAFETY:

HYDROCOTE 3061I epoxy paste adhesive, Component B, contains an alkaline amine. Prolonged or repeated contact may cause eye irritation and other allergic responses, such as skin irritation or dermatitis. Avoid contact with skin or eyes. Flush eyes immediately with water and contact a physician. If used indoors, provide adequate ventilation. Use soft-sided goggles, protective clothing, rubber gloves and barrier creams.

LIMITATIONS:

Minimum application temperature 40° F (4° C). To obtain maximum bond strength, local water conditions have to be taken into account and appropriate surface preparation procedures followed. For further information, contact your local Master Builders Representative. Shelf life is 24 months minimum when stored between 40° and 90° F (4° and 32° C). HYDROCOTE 3061I epoxy paste adhesives is an industrial product and is not intended for household use.

For additional information, contact your local Master Builders Representative.
