PERMABOND TA4811
Harmonization Code : 3907.30.00.40 | Epoxy Mold Compounds containing by weight more than 70 % silicon dioxide
Main features
- 1:1 toughened methacrylate chemistry
- Fast room-temperature cure
- Durable structural performance
Product Description
PERMABOND TA4811 is a two-part, 1:1 toughened methacrylate structural adhesive designed for bonding thermoplastics, thermosets, metals, and composites. The adhesive develops strong bonds to a wide range of substrates, including as-received metal surfaces without surface preparation. TA4811 cures rapidly at room temperature and features thixotropic, non-sag characteristics that support easy dispensing through static mixers while maintaining gap-filling capability. The cured adhesive offers high shear and peel strength, good impact resistance, chemical resistance, and durability in demanding industrial environments.
Key features
- 1:1 toughened methacrylate chemistry: Simplifies mixing and dispensing while supporting reliable structural bonding.
- Fast room-temperature cure: Provides a 4-6 minute working time, 10-15 minute fixture time, and full cure within 24 hours.
- Durable structural performance: Delivers high shear strength along with good impact, chemical, and environmental resistance.
Applications / Suitable for
- Bonding thermoplastics
- Bonding thermoset materials
- Metal assembly applications
- Composite component bonding
- Industrial assemblies requiring gap-filling and non-sag adhesive performance
