High performance primer designed to reduce coating adhesion loss on rivets
High performance primer designed to reduce coating adhesion loss on rivets
ANAC's 10P20-44M epoxy primer has been qualified to specification BMS 10- 72 Type IX. John Griffin, General Manager, ANAC Americas, explained that test results prove that combining a sol-gel type pretreatment with the new 10P20-44M primer is the most effective way to significantly reduce “rivet rash” which is a term used to refer to the selective loss of paint from metal rivet heads on aircraft. “Rivet rash” increases the risk of corrosion to the body of an aircraft and spoils the overall appearance of an aircraft's livery. This condition commonly occurs on forward sections of commercial aircraft. “Our 10P20-44M primer has been optimised and offers an unprecedented combination of adhesion, fluid resistance, and topcoat compatibility for premium in-flight performance,” he added. The product is also designed to work with conventional pretreatments commonly used in the aircraft industry, such as MIL-C-5541 chemical conversion coatings.
The new product has application and environmental benefits also. It achieves a smooth satin finish in just 3h, and does not require sanding, reducing process time. The generous pot life also minimises waste allowing an applicator plenty of time to utilise the complete contents. In addition, under US legislation, the product is low VOC. The combination of low VOC and high solids technology means it gives off less harmful VOC and HAPS emissions than conventional and waterborne primers.
ANAC's 10P20-44M primer is currently in use in the maintenance sector, and will now be available for new Boeing aircraft. Airlines may take advantage of this new technology on new Boeing aircraft by asking their Customer Engineer about 10P20-44M as part of the BMS 10-72 Type IX system.
