HUDCO Formula 3100

Tile and Structural Adhesive

HUDCO Formula 3100 epoxy adhesive is a high-strength adhesive. Supplied as two contrasting colored thixotropic pastes. The user can easily monitor while blending them into the third and final color. Its buttery viscosity and high thixotropy keeps HUDCO Formula 3100 in place during application. Although developed primarily for bonding ceramic tile to itself or to metal, it readily bonds to most other solid substrates and shows superior adhesion at temperatures up to 300' F. It is especially useful for bonding dissimilar materials where differential expansion and contraction during temperature variations or vibrations would cause release of other adhesives.

Typical Applications

  • Installation of ceramic tile to steel or aluminum.
  • All high strength bonding requirements for similar and dissimilar substrates.
  • General purpose adhesive where high strength is required with lap shear strength exceeding 3400 PSI.
  • Demonstrates superior adhesion at temperatures up to 300° F.

Application Instructions

Surface Preparation: 
(A) Surface of substrates must be clean and sound.
(B) 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.
(C) 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: Combine equal amounts of HUDCO Formula 3100 Resin with HUDCO Formula 3100 Curing Agent (Hardener) by weight or volume. Mix thoroughly for several minutes making sure all of the resin is blended with the entire curing agent. Accurate measuring and mixing are vital to complete curing and optimum performance.
Application: Apply product to prepared surface and use supplied tools to achieve desired finish.
Curing: Initial cure will occur in 2-4 Hours. In order for the product to reach its 300° F potential, it must be post cured for 8 hours at a temperature of 200° F or higher.
Safety Precautions
CAUTION: For Industrial Use Only. Keep Away From Children.
HUDCO Formula 3100 Resin contains epoxy resin which is harmful if swallowed. After prolonged exposure it may irritate skin and cause sensitization and/or dermatitis.
HUDCO Formula 3100 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 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 3100 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.
