Product Name
- Permabond TA4204 Cartridge (1:1) Toughened Acrylic Adhesive
Brief Description
- Permabond TA4204 is a 2-part, 1:1 mix ratio toughened acrylic adhesive designed for high-strength structural bonding. It offers fast curing at room temperature and a crystal clear appearance. This adhesive is capable of bonding a wide variety of materials, including metals, plastics, GRP, ceramics, and wood.
Popular Applications & Uses
- Magnet bonding, particularly for electric motors.- Manufacturing of metal and glass furniture.- Structural bonding, such as for aluminum panels.- Attachment of rear view mirrors.- Sign bonding, point-of-sale stands, and shop fitting displays.- Artwork and jewelry assembly.- High-speed production items like earphones and speakers.- Automotive exterior components and vehicle conversions, including campervans.- Bonding components for lifts, stairlifts, stairs, and walkways.- Interiors of buses, trains, and trams.- General assembly in consumer electronics and medical devices.
Industries that Commonly Use It
- Aerospace/Defense (for aircraft parts and components)- Automotive Service/Repair (for exterior components, mirror attachment, vehicle conversions)- Cabinet & Woodworking (for wood bonding and furniture manufacturing)- Construction/ Building Services (for structural bonding, lifts, stairlifts, stairs & walkways)- Electrical Services or Products (for magnet bonding in motors, loudspeakers, electronics)- Fabrication (for general bonding of diverse materials)- Furniture (for metal and glass furniture manufacturing)- General Manufacturing (for high-speed production and assembly)- LED/Electronics (for consumer electronics, earphones, speakers)- Marine (for GRP bonding and boat manufacturing)- Medical Device/ Prosthetics (for general medical device applications)- Metal Fabrication (for bonding metals and structural aluminum panels)- Plastic Fabrication (for bonding plastics, GRP, and composites)- Sign & Display (for point-of-sale, shopfitting, and signs)- Transportation/ Specialty Vehicle (for bus, train, tram interiors, and vehicle conversions)
Special and Unique Features
- Crystal clear appearance, ideal for bonding clear substrates like polycarbonate and acrylic.- Fast cure at room temperature, achieving handling strength in 5-10 minutes.- High shear and peel strength, providing durable and tough bonds.- Good impact and vibration resistance.- Good chemical resistance.- Bonds well to unprepared aluminum and is tolerant of surface contamination, including oily metals.- Can be used with or without a mixing nozzle (bead-on-bead application).- Offers better environmental resistance and more gap fill capability compared to instant adhesives like cyanoacrylates.

Comparison Note
- Permabond TA4204, as a toughened structural acrylic adhesive, competes with two-part room temperature curing epoxy and polyurethane adhesive systems.- It offers advantages such as higher tensile strength, greater flexibility than many epoxy adhesives, and good bond strength to a wide range of polymeric substrates.- This product provides better environmental resistance and more significant gap-filling capabilities compared to instant adhesives like cyanoacrylates.- A key benefit is its tolerance to surface contamination, allowing for good bond strength even on unprepared or oily metal substrates, which can simplify manufacturing processes.
