Clifton Hypalon adhesives

EoL recommends the use of DB 7020 adhesive by Clifton.

DB 7020 - PRODUCT INFORMATION

DB 7020 is a two-part polychloroprene based adhesive formulated to exhibit good adhesion to Neoprene, Hypalon, synthetic rubber foams,
urethane foam, leather, and hard-to-adhere synthetic fabrics. This product demonstrates excellent peel adhesion and good heat resistance. DB
7020 is designed primarily for the use in bonding Hypalon/Neoprene coated fabrics as found in the inflatable industry.

MIXING INSTRUCTIONS:
1. Dilute ACC7020 using MEK by adding 3 parts by weight of ACC7020 to 97 parts by weight of MEK.
DO NOT USE ACC7020 WITHOUT FIRST DILUTING AS ABOVE! Mix solution well to dissolve.

2. Mix 6.1 parts of above solution into 100 parts of DB7020 by weight, or 8.4 fl. oz./gal DB7020 by volume.
This equates to 66 cc’s of catalyst solution to one litre of adhesive.
This system has a 4 hour pot life.

SURFACE PREPARATION

It is necessary to buff all Neoprene/Hypalon coated fabrics prior to applying adhesive. Once buffed, use a cloth dampened with Toluene to clean
the fabric. It is recommended to clean a second time to remove any residual material. Once the coated fabric is cleaned and allowed to dry, apply
the first coat of catalyzed adhesive on both surfaces. Allow 30 minutes for the material to dry and apply a second coat of adhesive. The materials
must not be bonded until this second coat is dry to the touch. In addition to be adhered using this method, solvent reactivation may also be used.
Here, a cloth or brush dampened with MEK is wiped over both surfaces and the bonds are made when the adhesive is tacky to the touch. Once
mated, the seam should be rolled out with a two-pound metal roller.

Final adhesion levels are highly dependent on the coated fabric being used; however, bond levels of greater than 20 lbs /inch peel should be
achieved.
