- Product Features
- Two-part - Ratio not critical to end performance.
- Fast tack - Parts can be mated 5 seconds after spraying.
- Delayed mating - If desired, parts can be mated as long as 10 minutes after spraying.
- Color tint available - Aids in noting coverage and uniformity. Standard color is white.
- 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.
- Temperature range - The mixed adhesive when dry has a use range of -40 to 200°F

Bonding Capabilities
- Hydra FAST-EN® DC-13239 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. If bonding to open cell urethane foams, foam tears can result within minutes. Maximum strength is developed within 24 hours. It is within the 24 hour period that the residual water is dissipated. Full water resistance is developed in 3 to 7 days, depending upon ambient conditions.
- If repositioning is desired because of misalignment, parts can be realigned prior to pressure mating of surfaces. If pressure mated, respraying of parts is acceptable.
Coverage
Hydra FAST-EN® DC-13239 can be 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 open cell urethane foams, average laydown to achieve immediate hold 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 open cell urethane foams is:
Laydown Grams Wet per Sq. Ft. Approx. Sq. Ft. Coverage per Gallon Low 8.3 630 Normal 10.4 500 High 12.5 420 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-13239 (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 solid adhesive film. The following are recommended approximate mix ratios:
By Volume or Weight Viscosity DC-13239 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-13239 is compatible with several different external mix spray gun systems, some of which are available directly from H.B. Fuller. 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.
