Aeroflex Aeroseal – 1/2 pint

$10.00 $8.00


Aeroseal™ adhesive (amber or black in color) is a modified neoprene contact adhesive specially formulated for bonding Aerocel insulating materials firmly together. Aeroseal™ creates strong seams and butt joints that will operate at temperatures up to 257 degrees F. Aeroseal™ may also be used for adhering sheet insulation to flat and curved surfaces that will operate at temperatures to 180 degrees F. Aeroseal™ adhesive (amber or black) is also ideal for use with other materials like metal, cork board, polyurethane foam, rigid PVC sheet, formica, melamine board and rubber sheet. Aeroseal™ adhesive has a high water vapor resistance and weathering resistance to prevent moisture from penetrating joints, and forms a permanent bond to the applied materials for long lasting service.

Directions for Use

Stir contents thoroughly before use. Thinning is not recommended. Prepare both surfaces before applying adhesive by being sure they are dry and clean of any foreign matters. Apply a thin even coat to both surfaces to be bonded. Allow to dry but still tacky to the touch. Aeroseal™ will bond immediately upon contact, so it is necessary to position pieces accurately as contact is made. Moderate pressure should be applied over the entire area to assure that contact is complete.

It is recommended that the adhesive not be open for more than 10 minutes at a time and be applied only at temperatures above 40 degrees F. Do not apply to heated surfaces. If application is necessary under 40 degrees, extra care must be taken in application and closing the joint. Application below freezing (32 degrees F) is not recommended.

Where application is in an area that will operate at higher temperatures, it is recommended that the adhesive be cured a minimum of 36 hours to attain heat resistance assured to the temperatures stated in the description paragraph of this publication.

Although Aerocel insulation does not require protective coating, if coating is required, all bonded joints should be allowed to cure for at least 24 to 36 hours. When sheet material is installed requiring full surface coverage of adhesive, it is recommended the insulation be allowed to cure for one full week before coating is applied.
