BR-127

BR-127 Is a modified epoxy primer which is yellow in appearance and is the most common adhesive bond and corrosion inhibiting primer used in commercial and defence Aircraft and Motorsport applications.

BR-127 primer is used to inhibit corrosion on metal parts and provides excellent bonding with the majority of all film adhesives and offers optimal structural performance at temperatures ranging from -67°F to 302°F (-55°C to 150°C). BR-127 is offered by The Diamond Metal Finishing Co Ltd with several options of pre-treatment application, either by chemical etching, chemical conversion coatings, but mainly with our Phosphoric acid anodising (PAA) treatment. The latter being the ultimate preferred choice for most aerospace applications. As this product contains Strontium chromate, we have re-classified this product within our special processes category [SP].

Our highly trained operatives ensure that the prepared substrates are coated within specific timescales and measure coating thickness to ensure process compliance.

All parameters are recorded within our PLC controlled equipment which also records all times, oven temperatures, voltages and of course all records relating to stock control and storage conditions of primers.

Once completed and parts have successfully passed our quality checks, they are released via our AS9100 D management system with relevant documentation including Certificate of Conformance etc. From quotation through to individual packaging requirements we ensure the best and most cost-efficient solution for your parts.
