PRODUCT SPECIFICATION

TUFFBOND for Rubber Toughened

Cyanoacrylate Adhesive

DESCRIPTION

Tuffbond for Rubber Toughened is a black ethyl Cyanoacrylate, with higher peel and shock resistance than other grades . Tuffbond for Rubber Toughened with a longer setting time than regular Cyanoacrylate adhesive and it allowed enough time for users to put materials together after application. It has been specially formulated to achieve the strongest possible bond between well-mated, non-porous surfaces, such as rubber, metals, plastics, glass, etc. Tuffbond for Rubber Toughened 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 Rubber Toughened 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 Rubber Toughened if left    uncapped, may deteriorate by contamination from moisture in the air.

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

PRECAUTION

 

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.
