MUNSTER, GERMANY: Weicon GmbH & Co KG, a manufacturer of adhesives and sealants from Germany has developed a new adhesive that is especially suitable for bonding different types of plastic – Weicon Easy-Mix RK-7300.
It is a fast curing, solvent free structure and construction adhesive based on methyl methacrylate (MMA).
The adhesive has a high-strength and a high viscosity. It is impact resistant and withstands both static and dynamic loads.
Special fillers (glass beads), which have been added to the product, ensure a consistent bonding line of approx. 0.25 millimetres. The adhesive allows a maximum gap-bridging of one millimetre.
Bonding of plastics
The adhesive adheres perfectly to a variety of plastics and has a high adhesive strength. High-strength bondings are possible even in the case of low-energy plastics which are difficult to bonds, such as PE or PP.
“RK-7300 is a universal multi-talent when it comes to the bonding of a wide variety of plastics,” said Holger Lutfring, product manager at Weicon.
The application of the new adhesive is not limited to the permanent bonding of various plastics. Its high viscosity characteristics also permit material pairing with different expansion coefficients, such as plastic with aluminium or steel.
Many applications
The adhesive is particularly suitable for use in the plastics processing industry. RK-7300 can also be used in a variety of applications, including other areas, such as mechanical engineering or rail vehicle construction.
