Hydra FAST-EN® DC-13634

1 of 23 products in this brand
Hydra FAST-EN® DC-13634 is a two-part sprayable adhesive for bonding open-cell urethane foams to other porous or non-porous surfaces. It can bond various materials, such as other open- or closed-cell foams, plastics, fabrics, some woods, and metals. The adhesive has good wet grab and can create immediate bonds. It is user-friendly and solvent-free, addressing common problems found in other two-part systems. This product is suitable for applications where solvent-based, flammable, or non-flammable systems are a concern for health or environmental reasons.

Features & Benefits

Product Features
  • Two-part - Ratio not critical to end performance
  • Fast tack - Good wet grab, repositionable, and parts can be mated immediately after spraying
  • Delayed mating - If desired, parts can be mated as long as 10 minutes after spraying
  • Color tinted - Aids in noting coverage and uni-formity: Standard color is charcoal. Other colors are available.
  • Environmentally Friendly - Neither wet nor dry adhesive is considered a RCRA hazardous waste
  • Equipment friendly - 2 parts are mixed external to the spray gun
  • Shear stability - Part A and Part B are not affected by normal shear forces generated by mechanical pumps or mixers
  • Water-based for easy clean up
  • Temperature range - The mixed adhesive when dry has a use range of -50 to 190°F

Bonding Capabilities

  • Hydra FAST-EN® DC-13634 will allow sprayed parts to be bonded within seconds after application of the adhesive to both mating surfaces.
  • Parts can be handled immediately after mating. Foam tears can result within minutes, but will depend upon the substrates bonded. However, maximum strength is developed within 24 hours. It is within the 24 hour period that the residual water is dissipated.
  • If repositioning is desired because of misalignment, the system accommodates this characteristic. Parts can be realigned prior to pressure mating of surfaces.

Coverage

Hydra FAST-EN® DC-13634 is color tinted to aid in the determination by the operator of the correct amount to be applied. Custom colors are available at no extra charge. The coverage rate needed to achieve the desired level of adhesion will need to be established for each particular application. This rate will depend on the substrate's surface texture and bonding properties. In the case of urethane open cell foam, average laydown to achieve immediate holding power will depend upon properties such as density and compression.

The approximate single surface coverage of one gallon of Part A with the correct ratio of Part B when applied to PU foam is:

Laydown Grams Wet per Sq. Ft. Approx. Sq. Ft. Coverage per Gallon
Low 12.5 600
Normal 10.4 480
High 8.3 460

Once the coverage rates have been determined, color standards can be established and samples supplied to operators which indicate the desired shade of color
(i.e., blue) to be applied to the part. The color tint also aids the operator in determining if even coverage is being achieved.

Hydra FAST-EN® DC-13634 (Part A) requires the use of DC-12239 as an activator (Part B). Part B flow rate should be adjusted to guarantee full conversion of Part A to a sol-id adhesive film. The following are recommended approx-imate mix ratios:

  By Volume or Weight Viscosity
DC-13634 Part A 100  
DC-12239 Part B 10 - 20 Water thin

These parameters are adjusted by air pressure settings to the required levels to achieve the effect desired. The air supply used must be consistent (no wide fluctuation in line pressures) and be oil free to achieve the best results using this system. Atomizing air pressures can be adjusted over a wide range to meet specific requirements.

Equipment Considerations

Hydra FAST-EN® DC-13634 is compatible with several different external mix spray gun systems. These systems are designed to deliver Part A and B materials to the spray head via air pressure. Each part has its own pressure setting. Part B is delivered to the spray head and introduced to Part A external to the spray head, which minimizes spray head clogging problems.

Easy Clean-up

  • Since the mixed Part A and Part B are not in contact internal to the spray equipment, it is not necessary to clean the gun often. If the gun is to be used again within 16 to 24 hours, the gun can be left as is (with system pressurized) without any problems. It is recommended that the gun be cleaned every 5 days, or if it is not going to be used within 48 hours (i.e. over weekend).
  • Clean up is easily accomplished using commercially available liquid detergent in a water solution. Tap water alone is not recommended for clean up.
