PRODUCT SPECIFICATION

TUFFBOND for EPDM

Cyanoacrylate Adhesive

DESCRIPTION

TUFFBOND for EPDM is a low viscosity, fast curing single component Cyanoacrylate Adhesive, it is specifically formulated for difficult to bond substrates, particularly suited for bonding plastic or rubber (EPDM) parts. Where very fast fix Turing is required, TUFFBOND for EPDM is a one-component, solvent-free system and does not require the use of a catalyst, heat or clamps. When a thin layer of TUFFBOND for EPDM applied between two surfaces comes into contact with atmospheric moisture, a rapid polymerization occurs producing the ultimate bond.

DIRECTIONS  FOR  USE

 

1.Make sure the surfaces to be bonded are clean and dry (preferable to solvent-wipe plastics, glass, and rubber, and to acid-treat metals).      

2.Dispense a drop or drops to one surface only. Apply only enough to leave a thin film after compression.

3.Press parts together and hold firmly for a few seconds. Good contact is essential. An adequate bond develops in less than one minute.  (Maximum strength is achieved in 24 to 48 hours).

4.Wipe off excess adhesive from the top of the container and recap TUFFBOND for EPDM if left uncapped, may deteriorate by contamination from moisture in the air.

5.Because TUFFBOND for EPDM condenses by polymerization, sometimes a whitening will occur on the surface of the container or the bonded materials. Should this happen, wipe surfaces well with acetone.

PRECAUTIONS

 

1.            Use with proper ventilation. Avoid contact with skin and eyes.

2.            If contact with skin occurs, rinse with warm water or dissolve gradually with solvent such as acetone, dimethylformanide, or nitromethane. Do not try to remove forcibly.

3.            If adhesive gets into eye, keep eye open and rinse thoroughly. Seek medical attention immediately.

4.            Keep well out of reach of children.

5.            Keep adhesive in a cool, dry place 20-25(68-77oF). For long term storage, refrigeration (5oC or 40oF) is recommended.
