Gray Fast-Cure 2-Part Methacrylate Adhesive ~ W4S 55420FS (50ml 10:1 Mix / F-System)

Adhesive cartridge with one mixer ~ applicator gun sold separately

Description

Wired4Signs USA has worked together with a leading USA adhesives manufacturer to develop this fast-cure 2-part plastic epoxy methacrylate adhesive. The light gray color of this structural adhesive is especially suited to bonding aluminum substrates without obvious glue marks.

You can also use this fast-cure gray epoxy adhesive to rapidly and securely attach a wide range of materials together.

This is a two-part methacrylate, flexibilized, structural bonding adhesive designed for
the structural bonding of various substrates, including fiberglass, steel, aluminum, and
various plastics (not low energy surfaces). It provides high strength and very flexible bonds to the above reference surfaces with generally no preparation effort. It bonds very strongly to steel, stainless steel, and aluminum metals and will allow a great deal of movement of the substrates due to CTE (Coefficient of Thermal Expansion) differences.

This adhesive is not UV stable, and will yellow over time. This yellowing will not affect bond performance, but will affect bond appearance.

The shelf life of W4S55420 is twelve (12) months from the date of manufacture based upon continuous storage at room temperature (77°F or 25°C). Storage of W4S55420 adhesives in refrigerated compartments will extend the shelf life even more. Do not store W4S55420 adhesive or any other adhesives in a refrigerator which has food in it. Be sure to bring W4S55420 adhesives to room temperature for 24 hours before use, otherwise longer cure and fixture times may be expected. Long-term storage at temperatures above room temperature will shorten the shelf life of W4S55420 adhesives considerably. Storage at temperatures above 100°F or 38°C could shorten the shelf life to less than one month. W4S55420 adhesives contain no water, so freezing of the adhesive for short periods is permissible, but is not encouraged.

Key features

• Flexible - tolerates significant substrate movement (thermal expansion, vibration, etc.)
• Good gap filling
• Fast curing (2–4 minutes working time)

When to use

Use W4S 55420FS when you need a flexible adhesive with good gap filling and a fast cure.

(Use W4S 55420 when you need a normal working time, or W4S 55320 when you need a long working time.)
