Description
Permabond TA4205 is a high performance 2-part toughened acrylic adhesive designed for structural bonding of metals, plastics, composites, and many other materials. Supplied in a 50ml cartridge with a 1:1 mix ratio, this methacrylate adhesive provides fast curing at room temperature with high shear, peel and impact strength.
TA4205 is a slower curing version of Permabond TA4204, offering increased working time while maintaining excellent bond strength and durability. It bonds a wide variety of substrates including steel, aluminium, ABS, PVC, GRP, ceramics, wood and engineering plastics.
This structural acrylic adhesive provides strong and reliable bonds with good chemical resistance and impact strength. It can be dispensed using a static mixing nozzle or applied bead-on-bead without a nozzle, making it suitable for workshop use, fabrication, and production environments.
Permabond TA4205 is widely used in engineering, automotive, marine, construction and industrial assembly where high strength structural bonding is required with additional working time.

FAQ – Permabond TA4205 Toughened Acrylic Adhesive
What is Permabond TA4205 used for?
Permabond TA4205 is a two-part methacrylate structural adhesive used for high strength bonding of metals, plastics, composites and engineering materials. It is commonly used in automotive, marine, construction, fabrication and industrial assembly where a strong and durable bond is required.
What type of adhesive is Permabond TA4205?
Permabond TA4205 is a toughened acrylic (methacrylate) adhesive. This type of adhesive provides high shear strength, good peel resistance and excellent impact performance, making it suitable for structural bonding applications.
What materials can Permabond TA4205 bond?
TA4205 bonds a wide range of materials including steel, aluminium, stainless steel, ABS, PVC, GRP, composites, ceramics, wood and many engineering plastics. It is ideal for bonding dissimilar materials such as metal to plastic or composite to metal.
What is the difference between TA4205 and TA4204?
TA4205 is a slower curing version of TA4204.
It provides a longer working time, which makes it easier to position parts before the adhesive sets, while still offering the same high strength and durability once cured.
How fast does Permabond TA4205 cure?
TA4205 cures at room temperature and begins to set after a few minutes once mixed. The slower cure speed compared to TA4204 allows more time for assembly, making it suitable for larger parts or more complex bonding jobs.
Is Permabond TA4205 a structural adhesive?
Yes, TA4205 is a structural methacrylate adhesive designed for load-bearing applications. It provides strong, durable bonds with good resistance to impact, vibration and environmental exposure.
Can TA4205 bond metal to plastic?
Yes, methacrylate adhesives like TA4205 are designed to bond dissimilar materials such as metal to plastic, plastic to composite, or composite to metal. This makes it a popular choice for automotive, marine and engineering work.
Does Permabond TA4205 fill gaps?
TA4205 can fill gaps up to approximately 1mm, allowing it to bond parts that are not perfectly flush. This makes it suitable for fabrication, repair work and structural assembly.
Does Permabond TA4205 require a dispensing gun?
Yes, the 50ml cartridge requires a suitable dispensing gun and static mixer nozzle to achieve the correct 1:1 mix ratio. The adhesive can also be applied bead-on-bead for certain workshop applications.
Can Permabond TA4205 be used for automotive or marine repairs?
Yes, TA4205 is widely used in automotive, marine and industrial applications for bonding panels, brackets, housings, composites and structural components where high strength and durability are required.
How should surfaces be prepared before using TA4205?
For best results, surfaces should be clean, dry and free from oil or grease. Light abrasion on metals or plastics can improve bond strength, especially for structural applications.
When should I use methacrylate instead of epoxy?
Methacrylate adhesives like TA4205 are often better than epoxy when bonding different materials together or when impact resistance is required. They also cure faster and usually need less surface preparation than epoxy adhesives.
