PERMABOND UV7141, Dual-Curable Glue - UV or Anaerobic curable glue for bonding ceramics, glass, mirrors and metals

Product Name

PERMABOND UV7141, Dual-Curable Glue - UV or Anaerobic curable glue for bonding ceramics, glass, mirrors and metals

Brief Description

PERMABOND UV7141 is a high-performance, dual-curable adhesive that utilizes both UV light and a secondary anaerobic cure mechanism. This methacrylate ester-based, 100% solids, solvent-free, colorless liquid is engineered for bonding materials like ceramic-coated glass, mirrors, glass, and various metals. Its dual-cure capability ensures complete curing even in "shadow areas" where UV light cannot fully penetrate, making it ideal for complex assemblies and opaque substrates.

Popular Applications & Uses

- Bonding ceramic-coated glass, mirrors, and glass to metals.- Assembly of glass furniture and display cases.- Attaching metal hinges to mirrored doors, such as for bathroom cabinets.- Applications requiring rapid fixturing with UV light and a complete cure in shadowed or opaque areas.- General assembly where high strength and environmental resistance are critical.

Industries that Commonly Use It

- Artist, Artisan- Automotive Service/Repair- Cabinet & Woodworking- Construction/ Building Services- Distributers & Resellers- Electrical Services or Products- Fabrication- Furniture- General Manufacturing- Government & Military- Industrial Supply- LED/Electronics- Medical Device/ Prosthetics- Metal Fabrication- Military- Sign & Display- Transportation/ Specialty Vehicle

Special and Unique Features

- **Dual Cure Mechanism:** Cures rapidly with UV light for quick fixturing and then fully cures anaerobically in shadowed areas.- **Shadow Cure Capability:** Ensures complete bonding even when UV light cannot reach all parts of the adhesive joint.- **High Shear Strength:** Provides robust and durable bonds.- **Excellent Environmental Resistance:** Withstands various environmental factors, including moisture and temperature fluctuations.- **100% Solids, No Solvents:** Environmentally friendly with low VOC emissions.- **Colorless and Optically Clear:** Ideal for "invisible joints" and aesthetic applications.- **Fast UV Fixture Time:** Allows for immediate handling of components after UV exposure, reducing the need for jigging.

Comparison Note

PERMABOND UV7141 stands out due to its unique dual-cure mechanism (UV and anaerobic), which provides the speed of UV curing for initial fixturing and the reliability of an anaerobic cure for areas inaccessible to UV light. This overcomes a common limitation of single-cure UV adhesives, which require full light exposure. While other dual-cure adhesives exist (e.g., UV/heat or UV/moisture), UV7141's anaerobic secondary cure is particularly effective for bonding opaque materials like metals or ceramic-coated glass where oxygen is excluded from the bond line. It offers excellent adhesion to glass, ceramics, and metals, high shear strength, and environmental resistance, making it a versatile choice for demanding applications requiring both speed and comprehensive cure.
