Product Description of
PERMABOND® TA4820
PERMABOND® TA4820
is a 2-part, 1:1 toughened methacrylate adhesive designed for bonding thermoplastics, thermosets, metals and composites. TA4820 has excellent adhesion to as received metal surfaces, forming high strength bonds without surface preparation. It provides excellent durability and resistance to many common industrial solvents and fuels, as well as harsh environmental conditions. It cures rapidly at room temperature and its thixotropic properties allow for easy dispensing through static mixing nozzles, while maintaining good gap-filling and non-sag properties. The long fixture time allows for accurate alignment of larger components.

Surface Preparation
Surfaces should be clean, dry and grease-free before applying the adhesive. Permabond Cleaner A is recommended for the degreasing of most surfaces. Some metals such as aluminium, copper and its alloys will benefit from light abrasion with emery cloth (or similar), to remove the oxide layer.
