Applications & Uses

Limitations

• Always test plastic materials for compatibility when using solvent-based products.
• Make certain this product is completely dry and the area free from solvent odor if food is involved.
• Not suggested for sealing vapor barrier jackets.
• Allow to dry to a solvent-free condition before installing weld pins.
• Overhead applications may require mechanical fasteners.

Preparation and Application Information

Material Preparation

DO NOT THIN. Stir well, but do not use sticks or boards, which would splinter or otherwise contaminate the product. No need to prime aluminum or galvanized metal. Apply only to clean, dry surfaces. Keep container closed when not in use to prevent solvent evaporation.

Application

Brush

Use a clean paintbrush. Uniformly, apply to metal surface at 200 – 400 sq. ft./gal. (4.9 – 9.8 m2 /l). Press insulation into place, making sure complete contact is made with applied adhesive. Bond may be made within 0 to 15 minutes.

Spray

May be spray applied with conventional air atomizing equipment or airless spray equipment. For spray equipment information, please consult spray recommendations or contact your spray equipment supplier. Average viscosity range: 200 – 500 cps.

Clean Up

Use solvents such as chlorinated solvent (non-flammable) or mineral spirits (flammable) for cleaning brushes and equipment.
