Socomore BOLICONE M4 Silver Part-A Aluminum Coating – 0.87 Kg for Aerospace Corrosion Protection

Socomore BOLICONE M4 Part-A is a silver-colored, aluminum-pigmented two-component coating from Socomore — a specialized aerospace chemical product company — providing cathodic (galvanic) corrosion protection at dissimilar metal interfaces on aircraft structures where conventional primer systems alone may be insufficient to prevent galvanic corrosion in service. BOLICONE M4 is used in Airbus and other European aerospace manufacturer applications where aluminum-rich coatings are specified for specific structural joint locations requiring galvanic protection.

Galvanic corrosion occurs when two dissimilar metals are electrically connected in the presence of an electrolyte (moisture/condensation) — the more noble metal is protected at the expense of the less noble metal, which corrodes preferentially. Aluminum-pigmented coatings like BOLICONE M4 provide sacrificial cathodic protection by making the coating itself the anode — the aluminum pigment particles corrode preferentially, protecting the steel or titanium structural component in contact with the aluminum airframe structure.

The 0.87 kg can provides a practical quantity for component-level coating, structural joint treatment, and maintenance repair applications where BOLICONE M4 is specified by the applicable aircraft SRM or engineering documentation.

Technical Information

BOLICONE M4 Part-A contains high-loading aluminum pigment flakes dispersed in a two-component epoxy binder base. The aluminum flake pigment provides the sacrificial anode mechanism — metallic aluminum with a more negative electrochemical potential than steel or titanium corrodes preferentially when the coating system is breached and electrolyte contacts the metal interface. The high aluminum pigment loading in BOLICONE M4 ensures adequate pigment connectivity throughout the coating film for sustained cathodic protection even after partial pigment consumption from sacrificial corrosion action.

The epoxy binder system of Part-A reacts with Part-B hardener to form a rigid, adhered coating film that bonds the aluminum pigment to the structural surface while protecting the coating from the physical and chemical environment of the aircraft structural joint. The epoxy chemistry provides excellent adhesion to aluminum, steel, and titanium substrates and resistance to the hydraulic fluids, fuels, and moisture present in aircraft structural zones.

Mix Part-A with Part-B at the specified ratio per the Socomore BOLICONE M4 product data sheet before application. Apply by brush or spray per the applicable aircraft SRM procedure for BOLICONE M4 use on your specific aircraft type.

Frequently Asked Questions

Q: What is Socomore BOLICONE M4?
A: BOLICONE M4 is an aluminum-pigmented aerospace coating providing sacrificial cathodic protection at dissimilar metal interfaces on aircraft structures — the aluminum pigment corrodes preferentially to protect the underlying structural metals.

Q: MPN for BOLICONE M4 Part-A 0.87kg?
A: MPN is 032B5100SR.

Q: How does aluminum-pigmented coating prevent galvanic corrosion?
A: The aluminum pigment provides cathodic protection — aluminum’s more negative electrochemical potential causes it to corrode sacrificially, protecting the adjacent more-noble metal (steel or titanium) from galvanic corrosion.

Q: Is BOLICONE M4 approved for Airbus aircraft?
A: BOLICONE M4 is a Socomore product used in Airbus-specified applications. Verify the applicable Airbus SRM or process specification for the specific usage and approval on your aircraft type.

Q: What is Part-B for BOLICONE M4?
A: BOLICONE M4 is a two-component system requiring Part-B hardener mixed with Part-A at the specified ratio. Consult Socomore’s product documentation for the Part-B product and mixing ratio.
