Silane based technologies are a new generation of non-chromate liquid treatments for magnesium. These multi-purpose coating systems were developed to inhibit corrosion on non-painted surfaces and to improve the performance of most painting systems.
Silane based technologies are the perfect “green” coating systems for magnesium and do not include any heavy or rare-earth metals. They can be applied as a two or four-stages immersion (spraying, brushing and rolling) process for most magnesium alloys and impart good corrosion protection.
Next treatments in this group are commercial available at the present time:
AMTS-S-0610 (OXSILAN® MG 0610):
-
Class 1: Bare corrosion protection. It is used mainly for temporary protection of magnesium during storage and shipping as well as for protection of magnesium components in manufacturing stages.
-
Class 2: Paint adhesion. It is used mainly for pre-treatment of magnesium prior to painting and powder coating. AMTS-S-0610 Class 2 is the preferred pretreatment for most aircraft paint systems.
-
Class 3: Bare corrosion protection, paint adhesion and electrical conductivity. It is used when good balance between bare corrosion protection and paint adhesion is needed. AMTS-S-0610 Class 3 is the preferred treatment for electronic magnesium components.
AMTS-S-0611 (OXSILAN® MG 0611):
-
Class 1: Bare corrosion protection. This coating offers the best corrosion protection for magnesium per 1 micron of coating thickness. It is also used in selective coatings together with anodizing, ceramic coatings, paint and powder coatings.
-
Class 3: Bare corrosion protection and electrical conductivity. It is the preferred coating for electronic magnesium components.
AMTS-S-0612 (OXSILAN® MG 0612):
-
Class 1: Bare corrosion protection. This coating modifies the magnesium surface and imparts high hydrophobic properties.
-
Class 3: Bare corrosion protection and electrical conductivity. This class is recommended for electronic devices.

Composite coating
AMTS-C-7266 (Gardobond®X4729)
AMTS-C-7266 is a special composite coating that was developed for magnesium to replace phosphate conversion coatings. It provides a thick crystalline layer (up to 50 microns) with high porosity. The layer can be additionally impregnated by special environment friendly sealers. AMTS-C-7266 is our recommended coating for magnesium sliding components. It also offers excellent paint, E-coat and powder coating adhesion. AMTS-C-7266 is the preferred pre-treatment for PTFE coatings.
Fluoride treatments
Fluoride treatments are traditional non-chromate treatments in automotive and general industries. Although they don't possess bare corrosion resistance they offer excellent paint adhesion and can be used prior to painting, powder coating and E-coat.
Gardobond® X4707 is one of the best and most stable representatives in the group.

| Anodizing |
|
Plasmo-gel anodizing for magnesium ALGAN 2M has replaced our old ALGAN 2 aircraft approved process. ALGAN 2M offers excellent bare corrosion protection for magnesium and also can be used as a paint pre-treatment in high corrosive environments (e.g. sea water). Aircraft magnesium components coated by this process have improved flammability resistance.
High bare corrosion resistance of ALGAN 2M may be improved by special environment friendly sealing.

Micro-arc Oxidation
|
|
ALGAN 4 MAC is a micro-arc oxidation process optimized for magnesium alloys. This process provides a thick ceramic coating with high bare corrosion and wear resistance. The coating has high thermal resistance and may be used for thermal isolation of magnesium components.
|
| Environmentally friendly sealing technology |
|
AMTS uses patented technology to provide high performance sealing of anodizing and ceramic coatings by silane based sealers. The greatest advantages of this technology are high improvement of bare corrosion resistance, low temperature application and short process time.
The technology was developed for our anodizing and micro-arc oxidation processes, however it is also applicable with other commercial anodizing and ceramic coatings.
|
| Selective coatings |
|
All our surface treatment technologies are compatible with one another. This advantage allows us to provide perfect selective coatings technology. Our selective coatings technology has significantly reduced costs and possesses many advantages when applied to precise aircraft components.
