We were recently approached by a cladding company looking for a fire-retardant adhesive. There are quite a lot of these around, but this company had particular requirements that meant a more tailored solution was needed. They wanted a product with high structural bonding strength, high peel strength as well as rapid strength development in order to make their production lines as efficient as possible. With this brief in hand, Permabond got to work on a solution.<\/p>\n

What resulted is Permabond TA4230 – a fire-retardant adhesive that\u2019s tougher and faster-curing than other fire-retardant products on the market. In addition to its fire retardancy, the adhesive incorporates a groundbreaking surface adhesion technology. This allows for the high strength bonding of aluminium surfaces (or other metals) without having to abrade and remove the oxide layer. It is also highly tolerant of oil or other contamination, so is ideal for applications where extensive surface preparation is not feasible.<\/p>\n

Permabond TA4230 isn\u2019t just any fire-retardant adhesive – it\u2019s certified fire-retardant to UL94 V-0 standard<\/a>. In practice, this means the adhesive doesn\u2019t just repel or contain fire, it actively quashes it. This is due to its intumescent nature, making it swell in the presence of fire into a protective layer, which puts the fire out almost instantly. You can see this in action in our comparative flame test below!<\/p>\n <\/p>\n
