Hudco Formula 4200

Wear Resistant Epoxy for Underwater and Wet Surfaces

HUDCO 4200 Epoxy is a high strength beaded wear 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 I part resin to I 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-C88l, Type III, Grade 3, Class B and C.

Typical Applications

  • May be applied underwater or to wet surfaces.
  • Repairs/Bonds wet concrete.
  • 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: 

(A) Surface of substrates must be clean and sound. Remove grease, oil, or other foreign material with acetone, wire brushing, or sandblasting. Acid etching the surface is acceptable if followed by thorough flushing with clean water.

 

(B) Roughen surface by grinding or sandblasting (3-5 mil surface profile) Surface must be completely dry with a minimum surface temperature of 75° F before applying.

 

Mixing:

Mix 4 parts of HUDCO 4120 HT Resin to 1 part of HUDCO 4120 HT Hardener by weight. Kits are supplied in the correct ratio. Ensure that the sides of the mixing container are scraped into the mixture. Mix several minutes, until consistent color is achieved.

 

Application: 

Apply product to prepared surface and use supplied tools to achieve desired finish.

 

Curing:

At 75°F, product will gel in 30 min. Initial cure will occur in 3 Hours. In order for the product to reach its 350°F potential, it must be post cured for 8 hours at a temperature of 200°F or higher.
CAUTION: For Industrial Use Only. Keep Away From Children.

 

HUDCO Formula 4120 HT Resin contains epoxy resin which is harmful if swallowed. After prolonged exposure it may irritate skin and cause sensitization and/or dermatitis.

 

HUDCO Formula 4120 HT 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.

  • Ingestion – Call a physician at once. Give milk or white of egg beaten with water. Then give a teaspoon 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.
HUDCO Formula 4120 HT Resin and Curing Agent should be stored in a cool, dry area. Shelf life is a minimum of one year in unopened containers when stored at 70° F – 85° F.
