Description

Aerodur 2100 MgRP is filled with magnesium and works by a cathodic protection mechanism, protecting aluminium the way zinc protects steel. It complies with AMS 3095A, TL 8010-0047, AER(EP) M-P-001 Type 1 Classes 1–3, GAMPS4002 and GMS 5008, gloss up to 10 GU, coverage 15.8 m²/l at 25.4 µm. Aerolith P27-CF is a chromate-free three-component polyurethane primer for fuselages and fuel tanks per AMS C-27725 Type III Grade 1 and 2. Metaflex SP 1050 is a one-component waterborne pretreatment for aluminium, composites and titanium (AIMS 04-04-072, ECS7118). P60-A with strontium chromate is compatible with enamels F70-A, F69, FR2-55 and FRS40 (AIMS 04-04-001…064, A2MS/BAMS 565-001, MEP 10-059 Type III, 37 m²/l at 15 µm), P60-LC has a reduced chromate content, and MSP-1 is chromate-free for aluminium and steel. For composites there are the waterborne epoxies P65-C and P65-C2K (MEP 10-118 and 10-133), the high-gloss P65-HG (AIMS 04-04-050) and Barrier Primer 37045 (AIMS 04-04-002/035/046).

How to choose

For aluminium without chromates use Aerodur 2100 MgRP with cathodic protection. For fuselages and fuel tanks Aerolith P27-CF is suitable, and for pretreatment Metaflex SP 1050. If a primer with strontium chromate under structural enamels is needed, there is P60-A, and for composites P65 with the variants C, C2K and HG. For a waterborne system of primers and enamels see Aerowave 2001, 2002, 2003, 3003 and 5001.
