- Non-Sag Placement Control
Product Description
LORD® 403 Acrylic Adhesive with LORD® Accelerator 19 Black is a two-component structural acrylic adhesive system designed to bond a wide range of prepared or unprepared metals and engineered plastics. The non-sag formulation remains in position on vertical and overhead surfaces and provides high impact and peel strength for assemblies exposed to low temperatures, environmental conditions and demanding mechanical loads. LORD Accelerator 19 improves high-temperature resistance and produces a black cured adhesive system.
Key Features
- Fast room-temperature processing with a 2–4 minute working time and handling strength in 4–6 minutes at 75°F (24°C).
- Broad substrate capability for unprepared metals and engineered thermoplastics, including polycarbonate, ABS and acrylics.
- Non-sag application supports vertical and overhead bonding while maintaining placement.
- Environmental and temperature resistance from -40°F to 300°F (-40°C to 149°C), with resistance to moisture, salt spray, weathering and indirect UV exposure.
Applications / Suitable for
- Structural bonding of prepared or unprepared metals
- Engineered thermoplastic assemblies
- Vertical and overhead bonding applications
- Assemblies exposed to high impact or peel loads
