L&L Products Thermoplastic Adhesive Film Helps Develop a Ballistic Heat Shield With Minimum Preparation Time & Without the Need for Primers

A composite customer was seeking an adhesive that would bond together layers of ultra-high molecular weight polyethylene panels for its ballistic heat shield. The solution needed to have minimum preparation time without the need for primers. It also needed to be compatible with a paint finish. L&L Products worked with the customer to come up with a solution using its thermoplastic epoxy adhesive film.

Thermoplastic Adhesive Film on Shield

Previously, in order to finish ballistic panels it would be necessary to apply an epoxy-based primer using a brush or spray equipment so that the paint would adhere to the surface of the ultra-high molecular weight polyethylene. After priming there would be a significant dwell time while the primer is allowed to fully cure.

The dry thermoplastic adhesive film can be applied directly on to the ultra-high molecular weight polyethylene surface. The panel is then placed in a heated press and adhesion to the panel’s surface is achieved in a few minutes. The minimum of preparation is then required for the surface to be made ready for the application of the paint finish. As the adhesive film is epoxy-based, it is compatible with the majority of paints used for ballistic armour applications.
