Fast curing adhesive bonds polypropylene and polyethylene

Written by: Tom Austin-Morgan | Published:

IRSL&LA-K540 from Intertronics is a two-component methacrylate based fast curing structural adhesive with high tensile strength and impact resistance. The fixture time is claimed to take between 45 and 60 minutes.

There is an increasing demand for a fast-curing structural adhesive capable of providing robust direct adhesion to low surface energy plastics. IRSL&LA-K540 from Intertronics is an innovative structural adhesive that combines direct adhesion – without primers or plasma, corona, or flame treatment – to low energy substrates such as polypropylene and polyethylene thermoplastics, with fast cure speeds at room temperature. IRSL&LA-K540 is also said to be capable of bonding a multitude of other substrates, enabling combinations of polyolefin plastics with metal and composite substrates.

The adhesive features high tensile strength and impact resistance with long term durability for applications in challenging operating conditions. It is resistant to weathering, e.g. salt spray and QUV radiation. IRSL&LA-K540 is suited for use in vehicle assembly applications.
