ARALDITE® CC 20

• Hazardous Air Pollutants (HAPs) free
• Qualifies for LEED®-NC & CI EQ Credit 4.4

Steps to apply the adhesive:

1. Stir adhesive before use.
2. Substrates should be clean and free of moisture, dirt, oil and other contaminates.
3. Adhesive & substrate should be at ambient temperature (>60°F) or above before apply adhesive.

4. The adhesive should be applied (See Suggested Equipment) at approximately 2.5 grams/square foot. The adhesive should cover 80% of the substrate surface first, the substrate surface should exhibit a uniform glossy sheen when the adhesive is completely dry. Dull areas indicate insufficient coverage, adhesive should be reapplied to these areas.

5. When bonding porous substrates, it is advisable to apply two coats of adhesive. The first coat will act as a sealer and prevent excessive absorption of adhesive into the substrate. After the first coat has dried, apply a second coat. Allow the second adhesive coat to dry completely.

6. Before assemble, check adhesive dryness, press adhesive surface with a spatula, if adhesive transfers to the spatula, additional dry time is needed; otherwise, the substrates are ready for bonding.

7. If areas have excessive adhesive deposition, twist the spatula while pressing them onto the adhesive layer. This will break the skin that may have formed as the adhesive being dried from surface down. If a skin has formed, allow additional dry time to ensure complete solvent evaporation before bonding.

8. Dry times can be shortened through the use of air movement, drying ovens, lamps, etc.

9. Substrates may be indexed together and bonded once the adhesive is dry. Bonds must be made within the open time of the adhesive. (Open times vary, see Application Data below) 10. Uniform pressure on the bonded laminates is necessary to create strong, lasting bonds. 40 pounds per linear inch is recommended to ensure complete fusion between the two layers of adhesive. A pinch roller is the ideal method for applying uniform pressure. When used properly, a J-roller can also provide sufficient pressure for bonding.

11. All contact adhesive bonds are able to be routed, trimmed, cut, filed and machined immediately.

Keep out of reach of children

• Do not use on polystyrene foams or plasticized vinyl.
• Do not mix with other adhesives. Thinning the adhesive is not recommended.
• For cleanup, use Choice Brands 689, a flammable cleaner or other cleaning solvent, such as toluene.

• ARALDITE® CC 20 should be stored in a dry place, in its sealed original container, at temperatures between 16°C - 27°C.
• Under these storage conditions the shelf life is 12 months from date of manufacture. Maintain tightly sealed after each use to prevent solvent loss and contamination.
• The product should not be exposed to direct sunlight nor to be exposed under refrigeration/freeze conditions.
