Add 6 to 7 ounces of water to 2.66 cups (or 1 lbs) of Ultra-CAT™ and mix thoroughly. Then add another 2 to 3 ounces of water and mix again. Continue mixing until material is lump free (3-5 minutes). This will create enough adhesive to cover approximately 50 square feet of substrate material.

*When measuring by volume, it is important to assess the measurement before the powder settles. A delay in adjusting the measurement will cause an error in the mixture ratio.

Mixing Process
Water is all that is necessary to start the reactive curing process of the Ultra-CAT powder.

If the Ultra-CAT powder will not easily and readily dissolve into the water, or if the mix appears sandy and/or grainy, the product should not be used. These working characteristics signal that the powder has passed its shelf life.

A thin spread is critical when working with raw veneer in order to reduce the effect of bleed through. Bleed through is the occurrence of glue seeping through the pores of the wood to show up on the face of the panel. Be aware of the thickness of your veneer and relative porosity of the species you're working with, and adjust the spread accordingly. In many instances, a thin spread coupled with mandatory open assembly time (perhaps up to 10 minutes) will be necessary to prevent excessive bleed-through. Take care not to let the glue dry-out if allowing open assembly time. It must still be wet enough to transfer to the mating surface.

Pot Life
Once mixed with water, the resin begins curing/hardening. The amount of time between when it is first mixed until it reaches the unusable point is termed pot life. As with most directions for gluing, this is a dynamic value. It will change, primarily due to temperature. Hotter temperatures yield a shorter pot life, and vice versa with colder temperatures. There is no problem putting mixed resin in the refrigerator to extend its pot life; however, it should not reach below 55°F, as it will thicken to the point where it will not spread well. Do not freeze the adhesive. If you opt to refrigerate the mixed glue, be sure to bring it back up to 70° before using it.

Assembly Time
The time you have after spreading the glue, before full press pressure is applied, is referred to as assembly time.  Urea resins offer very generous assembly times, making them ideal for intricate work requiring longer lay-up time.

Tips from Joe
The open time is critical! The open time allows the moisture to be absorbed by the adhesive so that the chemical curing process can begin. Don't rush to get the adhesive on to the substrate. Otherwise, the veneer and/or substrate may pull water from the adhesive preventing the chemical cure from occurring.

The minimim use temperature is 70°. When used below this temperature, the water will dry out before the chemical reaction with the powder can take place.

Stock Preparation
The best results are obtained with the best stock preparation. The closer these conditions are adhered to, the better the results.

Pressing/ Curing
As with pot life, both press pressure and cure time are dynamic, depending on the conditions at hand.

Ureas are water-based products and therefore can be cleaned up with water. Warm water is preferred, as either cold or hot water will make clean-up more difficult.

Because Ultra-CAT is extremely hygroscopic, it should be stored in a tightly closed container in cool, dry place at all times. You can expect 12 months of shelf life when Ultra-CAT is stored properly.

Keep in mind that the rated shelf life pertains to unopened containers stored in a cool (60°-70°F) and dry place. Higher temperatures will severely reduce the shelf life (only 6 months @ 90°F), and exposure to high humidity may cause severe lumping or actual catalyzation of the powder resin.

Times and Conditions
Open time: 20 to 30 minutes
Assembly time: 40 minutes
Pressing time: cold vacuum press - 4 to 6 hours @ 70°F
Pressing time: heated vacuum press - 2 to 4 hours @ 90°F
Dry shelf life: 12 months

Potential Cancer Hazard
Rats chronically exposed to 14-ppm formaldehyde contracted nasal cancers. Based on animal data and limited epidemiological evidence, NTP and IARC have listed formaldehyde as a probable human carcinogen. OSHA regulates formaldehyde as a potential human carcinogen.

May cause allergic skin reaction. Some reports suggest that formaldehyde may cause respiratory sensitization, such as asthma, ant that pre-existing respiratory and skin disorders may be aggravated by exposure.

OSHA has identified 0.5 ppm as the "Action Level"
29CFR 1910.1048. Please refer to the OSHA standard for guidance applicable to your
specific operations.

Section Six-Safe Handling and Personal Protection
Personal Protection
Where air contaminants can exceed acceptable criteria, use NIOSH/MSHA approved respiratory protection equipment. Respirators should be selected based on the form and concentration of contaminants in air in accordance with OSHA 29 CFR 1910.134 or other applicable standards or guidelines.
If airborne contaminants are generated when the material is heated or handled, sufficient ventilation in volume and airflow patterns should be provided to keep air contaminant concentration levels below acceptable criteria.
Safe Handling
Inhalation: Avoid prolonged or repeated breathing of vapor.
Skill: Avoid prolonged or repeated contact with skin.
Eyes: Avoid prolonged or repeated contact with eyes.
Handle in accordance with good industrial hygiene and safety practices. These practices include avoiding unnecessary exposure and removal of the material from eyes, skin and clothing. Wash thoroughly after handling.
