Permabond 4C20 Cyanoacrylate Adhesive

Product overview

PERMABOND 4C20 is an intermediate viscosity, medical device grade, cyanoacrylate that is used to bond through intermediate gaps. It is fast setting and suitable for use on plastics, rubber and metals.

Cyanoacrylate adhesives are single component adhesives that polymerize rapidly when pressedinto a thin film between parts. The moisture adsorbed on the surface initiates the curing of theadhesive. Strong bonds are developed extremely fast and on a great variety of materials.

Featured Properties

• Fast-setting
• Some gap fill ability
• Ideal for automated dispensing

Storage & Handling

Storage Temperature - 2 to 7°C (35 to 45°F)

Allow adhesive to reach room temperature before opening bottle to prevent condensation inside the bottle which can reduce shelf life.

Surface Preparation

Surfaces should be clean, dry and grease-free before applying the adhesive. Use a suitable solvent (such as acetone or isopropanol) for the degreasing of surfaces. Some metals such as aluminium, copper and its alloys will benefit from light abrasion with emery cloth (or similar), to remove the oxide layer.

Directions for Use

1) Apply the adhesive sparingly to one surface.

2) Bring the components together quickly and correctly aligned.

3) Apply sufficient pressure to ensure the adhesive spreads into a thin film.

4) Do not disturb or re-align until sufficient strength is achieved, normally in a few seconds.

5) Any surplus adhesive can be removed with Permabond CA solvent, nitromethane or acetone.

NB: For difficult or porous surfaces using a Permabond activator is recommended.If bonding polypropylene, polyethylene, PTFE orsilicone, prime first with Permabond Polyolefin Primer(POP).
