product overview

Apollo (A7504) was specifically developed for the manufacture of a wide range of panels, including sandwich panels, cold stores and caravans. It is a solvent-free one-component moisture-curing polyurethane adhesive (1K MCPU).

featured properties

• Extremely versatile: bonds a wide range of construction products and materials.
• Reduces equipment cost: developed to allow for manual application.
• Complete peace of mind: due to it’s high strength durable weatherproof bond.
• Minimises production cost: single-component adhesive with a low coat-weight and long open –time.
• Green Credentials: solvent-free polyurethane adhesive.

Developed for

• Panels
• Sandwich panels
• Cold stores
• Caravans

1. Ensure all surfaces to bebonded are clean and free from grease and other contaminants. Some grades of aluminum, galvanised steel and plastics may need priming.

2. Apply an even coat of the adhesive to one surface with a roller coater, trowel, scraper or an automatic bead-applicator.

3. The amount of adhesive required will vary according to the porosity/smoothness of the substrate and the method of application, but will be between 80-140g/m².

4. Mist the adhesive with water once it has been applied (approximately 10% of water based on the adhesive coat-weight).

5. Assemble the panel and place under pressure within the open-time (21 minutes). Pressure is usually applied usinga hydraulic press, vacuum table or bag press. The pressure required will depend on the nature of the substrates, but it is usually in the range of 0.5 to 0.9 bar.

6. Maintain pressure until the adhesive is sufficiently cured to permit handling of the bonded item (55 minutes).

7. Full cure of the adhesive will not be achieved for 24 hours. Keep handling to a minimum during this time.
