Permabond TA4207 is a convenient, multi-purpose, fast cure, 2-part, 1:1 adhesive, which achieves very high shear strengths on a wide range of metals and plastics, with little or no surface preparation. Even on difficult materials like PET-G, substrate failure is achieved with minimal acetone/IPA degrease and it performs outstandingly well on metals, cutting through oxide layers to form incredibly strong bonds with the parent material, and even achieves high shear strength on oily, unprepared steel. It can be applied with or without mixing nozzles (bead on bead).
FEATURES:
- Fast cure
- Very high strength on stainless steel, steel, aluminium, galvanised zinc & plastics
- High strength on hot-dip galvanised steel, electro-plated zinc & carbon fibre
- Substrate failure on PET-G & other plastics
- High-temperature resistance
- Minimal surface preparation required
- Excellent environmental resistance
- Convenient 1:1 mix ratio
APPLICATIONS:
- Sign bonding
- Shop fitting
- Fascias
- Prosthetic limbs
- Sports equipment
- Electronics
- Vehicle manufacturing – carbon fibre body panels
- Electro plated zinc fasteners, screws, nuts, bolts, switches
- Marine applications where environmental resistance is key
