Aerospace Coating

The document discusses the effectiveness of DMSO-based formulations for removing durable aircraft coatings like epoxies, polyurethanes, and polyesters. Tests show that DMSO blends can remove these coatings without harming surfaces or users. DMSO formulations meet military specifications, remove coatings completely and quickly, and have low corrosion and environmental impact potential compared to other solvents like methylene chloride and benzyl alcohol/peroxide mixtures. The document provides details on DMSO-based formulation considerations and guidelines for developing effective coatings removal systems.

DMSO PRODUCT INFORMATION BULLETIN

DMSO

dimethyl sulfoxide as a removal


solvent for durable aircraft coatings

Bulletin 160B

Oct 2007

Tests confirm that formulations utilizing Gaylord


Chemicals DMSO are highly effective in the removal
of durable coatings.
Gaylord Chemical Company, L.L.C. has developed data showing the utility of
DMSO solvent blends in removing a wide spectrum of surface finishes and primer
coatings including Epoxies, Polyurethanes, and Polyesters.
The
stringent performance requirements for aerospace top coatings and primer systems
(weatherability, UV resistance, corrosion protection) create a challenging
environment for those who must facilitate the removal of these coatings. Blends
utilizing Gaylord Chemicals DMSO help you meet the challenge by effectively
removing these durable finishes, without harming the surface or the user!

Use DMSO-based Formulations to:

Meet Military Specifications


Increase Speed of removal
Accomplish Complete removal
Maximize Shelf life

Gaylord Chemicals solutions-based approach has


contributed to the development and growth of
industries including pharmaceuticals, hydrocarbons, electronics,
Hansen Solubility Parame- polymers, coatings, agriter Methods provide a ra- cultural chemicals, and
tional guideline for formula- industrial cleaners.

tion development. Measurements made using a


standard 33 solvent set
show that aircraft strippers
have a limited
degree of formulation latitude, and only
the solvents
shown in the
circle on the
chart were effective at swelling / dissolving
important aerospace coatings.

Gaylord Chemicals headquarters are located in


Slidell, Louisiana with
manufacturing, research,
and development facilities
in nearby Bogalusa, Louisiana. GCC remains the
only producer of DMSO in
the Western Hemisphere.

DMSO can be effectively formulated in mixtures activated with acids,


bases, and other solvents. Testing shows that DMSO-based products outperform several types of control formulations, including the control sample given in federal specification TT-R-2918, a commercially available
benzyl alcohol / peroxide based product, and another type of solventbased system.
