Versatile Industrial BondingLord Parker 320/322 Epoxy Adhesives are engineered for applications across construction, automotive, transportation, electronics, solar, and general industry. They provide strong, durable adhesion between metal brackets and various substrates-enabling effective assembly without drilling or fasteners. Their exceptional compatibility with metals, composites, ceramics, glass, wood, and thermoplastics makes them an optimal choice for demanding bonding requirements.
High Strength and Environmental ResistanceWith a tensile strength of 4,440 psi and a holding power of 1.5 N/mm2, this adhesive withstands harsh conditions, including extreme temperatures, UV exposure, humidity, and salt spray. The cured epoxy retains its high impact resistance and prevents crack development even at sub-zero temperatures. Its resistance to solvents and protective coatings ensures excellent longevity in industrial environments.
Easy Application and Post-Cure FlexibilitySurface preparation is straightforward-clean with IPA wipe and abrade if necessary. The recommended glue thickness is 0.51-0.76 mm for optimal performance. Once fully cured, the adhesive can be easily filed, sanded, or machined like light metal, allowing for finishing adjustments as needed. The two-component system comes in user-friendly cartridges and features a shelf life of up to 24 months.
FAQ's of Lord Parker 320/322 Epoxy Adhesives:
Q: How should surfaces be prepared before applying Lord Parker 320/322 Epoxy Adhesive?
A: Before application, ensure surfaces are clean and free from grease or oil by wiping them with isopropyl alcohol (IPA). If bonding to metal with oxidation, lightly abrade the surface to remove any rust or oxidation. Proper surface prep maximizes adhesive strength and durability.
Q: What materials can be bonded with Lord Parker 320/322 Adhesive?
A: This adhesive system bonds a broad range of substrates, including metals (steel, aluminum), ceramics, glass, thermoplastics, wood, composites, and rubber. It is especially suitable for automotive assembly, solar panel installations, and industrial construction projects.
Q: When can the adhesive be machined or sanded after application?
A: Once the adhesive has fully cured, it can be filed, sanded, or machined just like a light metal. The post-cure process allows for finishing and adjustments to ensure a precise fit and clean appearance.
Q: Where is Lord Parker 320/322 most commonly used?
A: It is widely utilized in the construction, automotive, transportation, solar, electronics, and general industrial sectors. Specific applications include bonding metal brackets to concrete or ceramic tiles (without drilling), assembling vehicle panels, and potting electronic components.
Q: What are the environmental and safety benefits of this adhesive?
A: Lord Parker 320/322 contains no solvents, is non-flammable, and is virtually odorless, making it safer for users and the environment. It offers exceptional resistance to UV rays, humidity, temperature fluctuations, and chemical exposure, ensuring reliable long-term performance.
Q: What is the recommended bondline or adhesive thickness for optimal performance?
A: For most general bonding applications, maintaining a glue line thickness of 0.51-0.76 mm is recommended. This thickness provides optimal strength, flexibility, and impact resistance across a variety of substrates.
Q: How should Lord Parker 320/322 cartridges be stored for maximum shelf life?
A: Store the adhesive cartridges at temperatures between 18C and 27C to ensure a shelf life of up to 24 months. Keeping the product within this temperature range preserves its chemical properties and dispensing performance.
