Products for Industrial and Military Equipment

Introduction

We offer a complete line of non-stick, Fluorinated Polyurethane (FPU^TM) coatings to extend the life of your expensive equipment and machinery. We manufacture these patented polymers under licenses from the U. S. Naval Research Laboratory (NRL), which originally developed these coatings for military applications. The Navy Facilities Engineering Command (NAVFAEC) specifies FPU^TM for the interior lining of its welded-steel fuel tanks. Several of our systems are certified in the Lloyds Registry (for Refined Spirits Tanks, Crude Oil Tanks, and Bilge and Double Hull Void Spaces).

FPU^TM Protection, general properties

An FPU^TM surface has a very low surface energy (non-stick); it is chemically extremely stable (non-reactive), flexible, abrasion resistant, and impermeable to oxygen and water. FPU^TM provides:

• Barrier-effect corrosion protection. Its impermeability halts corrosion by preventing oxygen and hydroxide (OH) ions from reaching the metal surface.
• Long service life. Its chemical stability allows it to withstand heat and UV radiation without harm (e.g., it will not chalk). Its flexibility allows it to resist chipping. Some of our fuel tanks have been in service for 30 years.
• Hard to Soil. Its non-stick finish resists soiling and stays clean.
• Easy to Clean. Its chemical stability and abrasion resistance allows the finish to withstand cleaning. The non-stick surface cleans quickly and easily by hand, with power brush, or with moderate water pressure (e.g., a fire hose).

FPU^TM, specific advantages

FPU^TM has protective properties that are comparable to baked-on Fluorinated polymers (such as PTF or PVDF coatings) but it has two advantages. FPU^TM is:

• Mechanically Tough. It cross-links as it cures and therefore produces a mechanically tough surface.
• Field Applied. It cures at ambient temperatures, and therefore can be field-applied with standard painting equipment and touched-up as needed.

Applications

We manufacture several FPU-based products that are optimized for the following applications:

• Exterior Corrosion Protection
• Decks, Stairs, and Walkways
• Interior POL Tanks and Equipment Areas

Exterior Corrosion Protection

FPU WC-1^TM provides cost-effective FPU^TM protection for normal environments. It extends the life and preserves the appearance by preventing UV radiation damage, and inhibiting corrosion. The first picture on this page shows Mooranbah North Coal mining equipment, protected by WC-1^TM and WC-1 (AP)^TM.

FPU WC-1 (AP)^TM is a variety of WC-1 that is optimized for UV resistance, and for gloss and color retention.

FPU WC-1 (BA)^TM is a variety of WC-1 that is optimized to resist soiling by graffiti. The second picture on this page shows an engine of the Great Northern Rail in Australia protected with WC-1(BA) AntiGraffiti coating.

FPU WC-2 (H)^TM is a variety of WC-2^TM that is enhanced with PTFE to resist petroleum products. WC-2^TM is designed for mechanical toughness that is suitable for severe environments.

FPU WC-15^TM provides the same protective properties as WC-1, but it is optimized to be mechanically tough. WC-15 ^TM is recommended for splash zone applications where the coating must withstand, mechanical ware, UV radiation, and salt-build-up from repeated wetting and drying. It is ideal for off-shore facilities and sea-water intake structures. The fourth picture on this page shows a seawater intake structure in

Decks, Walkways, and Stairs

FPU WC-1 (NS)^TM is a variety of WC-1 that is blended with a soft, (non-cutting) traction-enhancing additive that provides a durable non-skid surface for wet or slippery floors, walkways, or stairs. The fifth picture on this page shows WC-1 NS^TM being applied to the loading dock at a Dixie Supermarket in Florida.

Tanks and Mechanical Areas

FPU WC-15^TM Is ideal for areas that are partially or fully immersed in fresh or salt water. One WC-15^TM system is approved in Australia (ICPW AS4020) for portable water applications. It is also Lloyds certified (MATS/2481/1) for Salt Water Ballast Tanks.

FPU WC-5^TM is optimized for applications that require resistance to petrochemicals and corrosive wastes but do not require UV protection. It is intended for interior applications such as machine rooms, or the lining of CHT tanks. It is Lloyds certified for Refined Spirits Tanks (MATS/2482/1), Crude Oil Tanks (MATS/2483/1), and Bilge and Double Hull Void Spaces (MATS/2484/1). Navy Facilities Engineering Command (NAVFAEC) specifies FPU^TM WC-5^TM for its new large (250 barrel to 300,000 barrel) shore-based fuel tanks. The last picture on this page shows one of the U.S. Navy's jet fuel tanks that has a WC-5^TM lining.

Systems

Steel Structures

A typical system for steel is as follows:

• Blast. Abrasive blast steel surfaces to White Metal in accordance with SSPC-SP 5 to achieve a surface profile of 1 to 2 mils. Air must be free of oil and moisture. Moisture dramatically shortens the pot life for the FPU^TM topcoats.
• Cleaning. Remove abrasive grit and dust by brushing and vacuuming.
• Temperature. Surface temperature during blasting and application should be at least 3 degrees F above the dew point and between 50 degrees F (10 degrees C) and 100 degrees F (38 degrees C).
• Striping. Brush-apply Epoxy Polyamide 21EP 150 Green primer to surface edges, seams, rivets, bolts, welds, and other irregular surfaces (see product descriptions for information on mixing, thinning, cleanup solvents, induction time, and drying time).
Priming. Apply Epoxy Polyamide 21EP 150, Green primer, 3 mils DTF.
• Intermediate Coat. Apply Epoxy Polyamide 21EP 151, Gray primer 3 mils, DTF.
• Finish Coat. Apply FPU^TM WC^TM Series 2 to 3 mils DTF.

Concrete Structures

A typical system for concrete is as follows:

• Cleaning. Clean free of dust washed surface with 2-3 Mils profile.
• Priming. Apply acrylic non-shrink filler, then a clear non-gloss Epoxy Sealer (ES010).
• Intermediate Coats. Epoxy Mastic Concrete Primer (EM32) 3-4 Mils DFT. Then Flexible Epoxy (21CC FE316) 4 Mils DFT.
• Finish Coat. Apply FPU^TM WC^TM Series 2 to 3 mils DTF.
