Hudco Formula 3200

Epoxy Adhesive for Underwater and Wet Surfaces

Description

HUDCO 3200 Epoxy Adhesive is a high strength structural adhesive/repair material, which was developed by HUDCO to bond to wet or underwater surfaces in addition to providing the reliable bonds associated with epoxies on dry surfaces. It is 100% solids, two-component system, which when mixed in the ratio of 1 part resin to 1 part curing agent (hardener), by weight or by volume, is a smooth non-sagging paste. It produces a strong trowelable mortar when mixed with an equal amount of dry sand, which also may be applied to vertical or overhead surfaces without sagging or runoff. It exceeds the requirements of ASTM-C881, Type III, Grade 3, Class B and C.

Uses

• May be applied underwater or to wet surfaces.
• Repairs/Bonds wet concrete. o High Strength Structural Bonds.
• Smooth Paste with no Vertical or Overhead sagging.
• Non-Shrinkable Protective linear Repair for pipes or equipment containing sewage or other water-borne materials.

Surface Preparation

Concrete
(A) Concrete substrates must be clean and sound. Remove grease and oil (if present) with an effective degreasing compound or strong industrial detergent.
(B) Remove scale, chipped or weak concrete.
(C) Acid etching the surface is acceptable if followed by thorough flushing with clean water.
(D) Apply to wet or dry surface.

Steel
(A) Best results are obtained by sandblasting to a white surface.
(B) Remove grease and oil with a suitable detergent or film-free solvent (Acetone).
(C) Remove any loose surface contamination.

Mixing

Combine one part of HUDCO 3200 Epoxy Adhesive resin with one part of HUDCO 3200 Epoxy Adhesive curing agent by weight or by volume. Mix thoroughly far several minutes making sure all the resin is blended with all the curing agent. Accurate measuring and mixing are vital to complete curing and optimum performance.

Handling Precautions

CAUTION: For Industrial Use Only. Keep Away From Children.

HUDCO Formula 3200 Resin contains epoxy resin which is harmful if swallowed. After prolonged exposure it may irritate skin and cause sensitization and/or dermatitis.

HUDCO Formula 3200 Curing Agent contains organic amine compounds which are harmful if swallowed. After prolonged exposure or repeated skin contact it may cause irritation, sensitization and/or dermatitis.

Emergency and First Aid Procedures

• Eye Contact - Irrigate with clean water for 15 minutes and call a physician.
• Skin Contact - Wash with soap and water.
• Inhalation - Remove to fresh air and provide oxygen if necessary.
• Ingestion - Call a physician at once. Give milk or white of egg beaten with water. Then give a tablespoon of salt in a glass of warm water to induce vomiting.

Protection Procedures

If used in a confined or an enclosed area, use an air supplied mask or respirator with canister for organic vapors and provide mechanical exhaust ventilation. Use protective gloves, safety glasses, and protective clothing. Avoid contact with skin and clothing. Contaminated clothing should be laundered before wearing again. Contaminated shoes should be thoroughly cleaned before wearing again.
