DESCRIPTION
The B3420 is a two-component, toughened methacrylate structural adhesive with a 10:1 mixing ratio. Engineered for primer-less bonding of composites, thermoplastics, and metals, it delivers superior performance in impact, peel, shear, compressive strength, and fatigue resistance across all bonded materials. With a rapid-setting formulation and a non-sag consistency, B3420 is ideal for vertical applications and can fill gaps up to 12mm.
Applications
B3420 is versatile, making it suitable for bonding various materials, including composites, thermoplastics, and metals. However, it is not recommended for use with polyethylene (PE), polypropylene (PP), PTFE, or polyacetals.
Key Features
- High strength and modulus
- Rapid setting and curing with a 5 - 8 minute work life
- Excellent environmental resistance
- Non-sag for vertical applications
- Gap fill capability of up to 12mm
B3420 is the ideal choice for structural bonding where strength, durability, and rapid cure times are critical.
