Sterling is a "pure aliphatic urethane" not acrylic. As a result, this produces the very toughest possible film and provides a flexible,
incredibly adherent and protective coat which retains that "wet" look like no other.
These hard glossy and pure polyurathanes have proved themselves superior both in northern and southern latitudes, where extreme durability in "high corrosion"
environments is required.
Sterling resists fuels, chemicals, salt water and impact. It requires only soap and water washing to maintain that bright and shiny lustre.
Stubborn grease, oil and paint collected on topsides can easily be removed with strong solvents without damaging the "Sterling Finish".
Thanks to the finsest primer systems in the coatings market, Sterling can cope with any surface - be it steel, fibergalss, wood, aluminum or plastic - protecting it against all exposure.
The following application systems are only intended as basic information. Please contact us for technical assistance or any further info you might require.
Polyurethane
coatings for aluminium
Surface preperation of unpainted
aluminum varies, depending on use and conversion methods of
the untreated metal.
In all cases, surfaces should be clean and free from any oxides, welding or mill contamination.
Surfaces should then be prepared using chemical conversion methods such as Amchem Alumiprep 33 followed by Alodine 1200-1201, or sterling M-3225 Wash Primer.
Primer should be applied within a maximum of several hours after Alodine treatment, the longer wait the less effective the Alodine. Follow the same procedure as for steel.
Polyurethane
coatings for fiberglass
Whether new or aged unpainted
fiberglass, the surface should be cleaned thoroughly with
Sterling c-8762, then rubbed with Scotchbrite pads. We do
not recommend sanding gelcoat since great care must be taken
not to open gelcoat surface and expose pinholes.
If surface is smooth, apply a tie-coat of Sterling U-3114 Epoxy Primer or U- 1000 P.U Primer, allow to flash. Then apply full coat of Sterling U-3114 or U-1000 to 5 mils / 125 microns wet film thickness.
Allow to dry, then sand with 220-440 grit paper, depending on the desired degree of smoothness and apply Sterling U-1000 Series Topcoat.
If the surface is severely damaged, apply 8 mils / 200 microns wet film coating of Sterling U-2705 Epoxy Fairing compound, allow to dry, sand smooth and apply a tie-coat of Sterling High Build Epoxy Primer. If necessary follow with U-3114 finishing primer. Finally, sand with 440 grit and apply Sterling Topcoat.
Polyurethane coatings
for bare or new wood
Unpainted wood should be clean,
dry and well seasoned. Green or wet lumber should never be
painted, as this will cause surface failure.
Fill all seams with high quality seam compound, preferably two-component polysulfide or polyurathane. Flexible compounds will move with the topcoat and avoid cracks and seperations.
Seal the bare wood with Sterling U-2555 High Build Primer to fill any deep voids and smooth the wood grain. Fair where necessary with U-2706 Epoxy fairing compound and re-prime with U-2555. Finish by sanding last coat
of High Build Primer with 180 to 220 grit paper. For optimum results apply U-1000 P.U. Finishing primer, sand with 280 to 320 grit paper and apply Sterling U-1000 series P.U. Topcoat.
Polyurethane
coatings for steel
Unpainted steel surfaces should
be clean, dry and and free from rust and contamination. When
possible, sandblast to white metal (SSPEC-10) finish with
a 2.5 to 4 mil profile. Remove all blasting media and residue
with clean, dry air and a stiff brush. Solvent wipe and dry.
Apply Sterling U-2554 High Build Primer over blasted steel surface to 10 mils / 250 microns dry film thickness and allow primer to cure.
Fair in low spots with Sterling U-2706 Epoxy Fairing compund. Allow to cure, and repeat as necessary. Following application of Fairing compound, overcoat the entire surface of sanded Fairing Compound with a tie-coat of Sterling U-2554 Primer.
Follow with Sterling U-2940 P.U. Primer. Apply consecutive coats is necessary, allowing drying time before sanding. Apply Sterling U-3114 Epoxy or U-1000 P.U. Finishing Primer, sand with 280-320 grit paper and apply topcoat.
