Current methods of tackifying fabrics often involve spray adhesives that have been shown in tests to have a detrimental effect on the mechanical properties of the composite. The amount of spray applied can vary greatly across the layup and from user to user. The effect this has on the cured laminate cannot therefore be predicted by engineers. Aside from the effect on the composite there are health concerns caused by the aerosol nature of the spray. HiMax™ DPA is optimized for each of these factors, allowing laminators to work more efficiently and in a safer environment. As bonding effectiveness is depending various factors like lay-up stack, weight, tool surface and geometry, all potential users should test HiMax™ DPA in representative conditions.

Storage & Handling
- Storage and Handling
Rolls of DPA and DPA coated fabrics should be stored horizontally to avoid “slippage” of the adhesive and subsequent loss of performance. Shelf life is 6 months at 21°C.
