PROTECTIVE & MARINE COATINGS

Business Case for Single Coat PaintsReview

U. S. Navy GoalsSingle Coat and Rapid Cure coatings for tank and void corrosion

control

Applicable to all tanks and voids within the U.S. Navy

15,000 tanks and voids (~129,000,000ft2)

1,612,000 gallons of coating required for preservation

$250M per year to preserve tanks and voids in fleet using current

materials and processes

U. S. Navy Achievements

Single Coat coatings now approved and specified for Class 5 (fuel), Class 7 (ballast) and Class 11 (boiler/reserve feedwater)

Single Coat optional in Class 13 (CHT)

Single Coat still needed in Class 9 (potable water)


Business Case for Single Coat PaintsBackground

• Business case based on paint only. Service Life issues are not addressed, but would favor high-solids and single coat products.

– Solvent based paints (Amercoat 235 or MIL-DTL-24441) 5-7 years in ballast tanks– 100% Solids paints (Amercoat 133) 15-20 years in ballast

tanks– 100% Solids, single-coat paints (Safe-T Plus) 15-20 years in ballast tanks

Cure Class Coating Chemistry

Standard Cure Traditional solvent based or solvent free epoxy

Rapid Cure Solvent free epoxy using enhanced curing agents

Single Coat Polyurethane and Polyurea with low catalyst levels


Single Coat Production Requirements

• Surface Preparation

– Same industry standard as for legacy (24441) and high solids (23236)

• SSPC SP-10 (Sa2-1/2) near white metal

• Soluble salts <3μg/cm2 or conductivity <30μS-cm

– Employs standard commercial process/equipment

• Environmental Controls

– Same industry standard as for legacy and high solids

• Relative humidity <50% using commercial dehumidification

• Application

– Commercial standardized plural component

equipment (COTS)

• Same equipment as for high solids.

• Equipment introduced to yards beginning in 1998

• Nearly all commercial applicators are certified
