Plastic Welder™ White

Brand: Devcon®

Package Sizes:

  • 400 mL Cartridge (DA160)
  • 47 mL Cartridge (DA291)

Product Description:

Plastic Welder™ White is a toughened structural adhesive that produces superior strength, load-bearing bonds to engineered plastics. It is designed for bonding PVC, fiberglass, ABS, FRT, PPO, PCBB, Metton®, Lomod®, Valox®, Noryl®, GTX, Minlon®, epoxy, RIM urethane, wood, and poorly prepared surfaces.

This adhesive performs well in outdoor weathering and solvent exposure environments. It features minimal surface preparation, room temperature cure, a 1:1 mix ratio, rapid fixture time, and a non-sagging formula.


Key Features:

Minimal Surface Preparation: Bonds effectively with engineered plastics, composites, and metals.
Fast Fixture Time: 8-10 minutes fixture time at 72°F (22°C).
High Strength & Toughness: Provides impact resistance of 22 ft.lb./in..
Solvent & Chemical Resistant: Withstands exposure to chemicals, motor oil, antifreeze, and acids.
Non-Sagging Formula: Allows for easy vertical applications.


Recommended Applications:

🔹 Automotive & Transportation: Bonding engineered plastics in vehicle components.
🔹 Construction & Industrial: Securing composite and thermoplastic assemblies.
🔹 Marine & Outdoor Use: Resistant to solvent exposure and weathering.
🔹 Plastic Repairs & Assembly: Bonds fiberglass, PVC, and various thermoplastics.
