Product Name
Permabond TA4810 Fast Set 4-6 min No-Primer Metals & Plastics Acrylic Adhesive (50ml And 400ml)
Brief Description
Permabond TA4810 is a two-part, 1:1 toughened methacrylate (acrylic) adhesive engineered for structural bonding. It is characterized by its fast cure at room temperature and its ability to create high-strength bonds across a diverse range of substrates, including metals, thermoplastics, thermosets, and composites. A key feature is its excellent adhesion to metal surfaces, often without the need for a primer. This adhesive offers exceptional durability and resistance to common industrial solvents, fuels, and harsh environmental conditions.
Popular Applications & Uses
- Structural bonding of dissimilar materials.- Assembly of components in various manufacturing processes.- Bonding of metals, a wide range of plastics, and composites.- Applications requiring rapid fixture and handling times to optimize production efficiency.- As an alternative to traditional mechanical fastening methods like riveting and welding.
Industries that Commonly Use It
- Aerospace/Defense- Automotive Service/Repair- Construction/Building Services- Electrical Services or Products- Fabrication- General Manufacturing- Government & Military- LED/Electronics- Marine- Medical Device/Prosthetics- Metal Fabrication- Plastic Fabrication- Sign & Display- Transportation/Specialty Vehicle
Special and Unique Features
- Fast cure at room temperature, with a pot life of 4-6 minutes and a fixture time of 10-15 minutes.- Achieves strong adhesion to many metal surfaces without the need for a primer.- Provides high shear and peel strength for robust bonds.- Exhibits good impact strength, enhancing durability in dynamic applications.- Offers excellent resistance to chemicals, industrial solvents, fuels, and harsh environmental conditions.- Thixotropic properties ensure easy dispensing through static mixing nozzles while maintaining good gap-filling capabilities (up to 2mm) and non-sag performance.- Capable of withstanding brief exposures to higher temperatures, such as those encountered during paint baking or wave soldering processes.

Known backups / known substitutes
- Other Permabond Structural Acrylics: Such as those with longer handling times (e.g., Permabond TA4200) or specific formulations tailored for particular metals or plastics.- Other 2-part methacrylate adhesives (MMAs): Products from manufacturers like 3M (e.g., Scotch-Weld Structural Acrylic Adhesives), Infinity Bond, Plexus, and Weicon.- Epoxies: Often used for high-strength metal bonding, though typically with slower cure times.- Cyanoacrylates: Provide very fast bonding but may not offer the same level of toughness, gap-filling, or impact resistance as toughened MMAs.- High Bond Structural Tapes: Can serve as an alternative to liquid adhesives in certain applications.
Comparison Note
Permabond TA4810 distinguishes itself with a unique combination of rapid cure, high bond strength, and exceptional adhesion to a wide array of substrates, particularly metals, without requiring a primer. Its toughened formulation imparts superior impact and peel strength, making it an ideal choice for demanding structural applications where both speed and long-term durability are paramount. While the market offers various acrylic adhesives, TA4810's specific balance of a fast set time (4-6 minute pot life) and its no-primer metal bonding capability positions it as a highly effective solution for efficient and robust manufacturing and assembly processes.
