FPU Industrial 501 Extra HD

FPU Industrial 501 Extra HD is a marine grade single coat glossy Highly Fluorinated Polyurethane topcoat with outstanding weather resistance, excellent colour and gloss retention with less than 5% fade-off over 10 years.

It is hard but flexible and abrasion resistant that cures through a wide temperature range.

When it fully cures it forms an extremely tough and abrasion resistant finish and is recommended for use over a variety of primed or powder coated surfaces.

Surface Preparation Direction for Use

Previously Painted, Powder-coated or Primed Surfaces:
The surface to be coated must be dimensionally stable, dry, clean and free of oil, grease, release agents, curing compounds and other foreign materials.

All bare areas must be primed with suitable primer:
New steel must be grit blasted & glossy surfaces should be roughened before re-coating. If any old paint that is peeling, flaking, cracking, blistering or lifting must be removed. Scuff sand glossy areas and aged epoxy coatings. All edges of the old coating must be feathered down to remove sharp edge.

Bare Steel

• All surfaces shall be free of loose rust, mill-scale and contaminants such as oil, grease, dirt and salts. Before any surface preparation is attempted, oil and grease must be removed by employing a suitable solvent cleaning.
  Use commercial Blast cleaning to remove mill-scale, rust and other contaminants and leave a roughened surface.

Concrete and Masonry

• Remove all loose particles, oil, grease, form release agents and any other contaminants.
• New concrete and masonry must be allowed to cure for a minimum of 30 days.
• Before painting, roughen the surface by abrasive blasting, acid etching or scarifying.

Special Notes

• Thinner consumption may vary depending upon site conditions.
• Practical covering capacity depends on application techniques, ambient conditions, wastage, surface conditions etc.

Mixing Instructions

First, stir until uniform or thoroughly until homogeneous mixing.

If the settling is observed in the base, loosen the settled material with help of hand stirrer followed by power driven stirrer.

For best results, use a spiral mixing blade at variable speed (400 – 600 rpm). Place the spiral mixing blade at the bottom of the container before turning on the mixer.

This will help to avoid inducting air into the material. Inducted air will cause “bubbles” in the coating when applied. Gently move the mixer head up to the surface while running.

This product has workable pot life 4 – 6 hours at ambient temperature.
Applying the material immediately after the 30 minutes induction time will provide best results. Note: Higher air & mixture temperatures will decrease the pot life and working time.

Application Information

Generally this paint is best applied by spray. Due to the rapid dry of this coating, only small areas may be coated by brush, applicator pad, or roller.
Care must be taken to achieve the specified wet and dry film thicknesses. Uniform, even coats must be obtained.

Large horizontal surfaces should be spray applied, however roller application can be performed.

Application Methods

• Spray – Use airless spray or conventional spray.
• Brush – Recommended for stripe coating and small areas, care must be taken to achieve the desired results.
• Roller – May be used for small areas but not recommended for first primer coat, however when using roller application care must be taken to apply sufficient material in order to achieve the specified dry film thickness.
