- Self-Leveling Flowable Placement
- Solvent-Free Bonding Formulation
Product Description
LORD® 363-A/363-B Epoxy Adhesive is a fast-setting, two-component epoxy adhesive designed to bond scuffed sheet molding compounds (SMC), wood, fiberglass reinforced plastics (FRP) and other supported plastics. Its self-leveling consistency flows into hard-to-reach areas and supports assemblies with tight tolerances. The solvent-free system can be cured at room temperature or with heat for faster processing.
Key Features
- Fast room-temperature cure with a 3–5 minute working time and handling strength in 15–30 minutes.
- Self-leveling consistency for flowing into hard-to-reach areas and bonding close-fitting parts.
- Solvent-free formulation that is nonflammable and virtually odorless.
- Room-temperature or heat curing to support different production requirements.
Applications / Suitable for
- Scuffed sheet molding compound bonding
- Fiberglass reinforced plastic bonding
- Wood and supported plastic assemblies
- Close-fitting parts and hard-to-reach bond areas
