Description
Devcon Flex Welder is an off-white, two-part methacrylate adhesive in a 50 mL cartridge for flexible plastic, composite, and dissimilar-substrate bonding. It is built for assemblies that need peel and impact resistance without a rigid, brittle bond line.
Devcon Flex Welder Benefits
- Non-sag paste helps hold the bead on vertical joints and shaped plastic parts.
- Flexible cured adhesive supports parts that bend, vibrate, or see repeated handling.
- Low shrinkage helps reduce print-through on thin or cosmetic assemblies.
- Room-temperature cure fits repair benches, fixture work, and production cells.
- 50 mL cartridge format supports controlled dispensing with a static mixer.
Use this adhesive for modified polyester, epoxy composite, and flexible or semi-flexible plastic assemblies where a rigid epoxy would be too stiff. The cartridge format is useful for small batches, service repairs, and jobs where operators need a repeatable mix without weighing resin and hardener.
Common Applications for Devcon Flex Welder
- Flexible plastic repair and assembly.
- Composite panel bonding where peel resistance matters.
- Transportation, marine, and equipment trim work.
- Bonding dissimilar substrates in fixtures, covers, and housings.
- Field repair kits that need a fast, cartridge-dispensed adhesive.
Compatible Materials and Equipment
- Modified polyester, epoxy composites, and many flexible or semi-flexible plastics.
- Clean metal and prepared plastic parts after a shop-approved surface prep process.
- 50 mL manual or pneumatic dispensing equipment with the correct static mixer.
