FGI 401HR Ceramic Thermal Transfer Coating

Unique Coatings Extreme Results


FGI-401HR is an extremely unique ultimate performance ceramic thermal transfer, corrosion and moisture protection coating. FGI-401HR is formulated to provide increased thermal transfer from the surface to a free flowing air environment, while maintaining high resistance to chemical and thermal breakdown of metal substrates. Increased thermal transfer allows components to operate at lower temperatures, creating gains in efficiency and extending part life. FGI-401HRs cutting edge ceramic technology is continually tested under extreme conditions, both in the laboratory and in the field, with excellent performance. Designed for ease of application and durability in a single component formula,

FGI-401HR is formulated using a unique air-dry PolyCeramic backbone, which is able to withstand temperatures in excess of 2600F, while having little effect on film integrity. While many coatings will micro crack and break down upon exposure to high temperatures, FGI-401HR uses this heat to flux and become harder and more abrasion resistant. FGI-401HR provides a very cost efficient coating with high-end performance.

Application Methods

Conventional spray equipment such as a 4oz HVLP gravity fed spray gun or small siphon type gun is recommended. Recommended film thickness is 1.5 to 2.0 mils. Preparation of substrate is crucial for maximum adhesion and performance of this material

1) Remove all coatings, oils, and contaminates from substrate with either a de-greasing chemical and/or by heating substrate to temperatures high enough to remove coatings or contaminates.

2) A blasted profile must be applied to the substrate to remove any carbon, scale, or other coatings. This is required to ensure maximum adhesion. For best results use a dry grit material such as aluminum oxide or garnet equivalent to a 100 - 120 mesh size. Remove any sharp edges or burrs that may create thin areas or protrude through coating.

3) Place parts in an oven at 300F for approximately 30minutes to evaporate any last minute moisture, oils, or contaminates that blasting or contact with skin have deposited on surface. (This is done on small parts.) Do not apply any solvents to substrate after a blast profile has been applied.

4) Hang or lay parts out to allow for best view and application access. Do not touch parts with bare skin.

5) Make sure FGI-401HR is completely mixed and no solids remain in the bottom of the container. Failure to completely disperse the product will result in poor chemical ratios and product failure.

6) Recommended spray equipment is a HVLP spray gun. The use of a small spray tip pattern will aid in coating hard to reach areas without excessive build up in surrounding areas. Material does not need to be thinned. Use as received.

7) Blow off substrate with a high-pressure air nozzle to remove any blasting dust left on the surface. Wear safety goggles or face shield for your protection.

8) Two applications of product are recommended for a 0.5 to 2.0 mil film thickness. In some cases a single coat will suffice for particular applications such as the 0.5 thickness. Work from the most difficult surface out to the easiest. This will aid in reducing runs or excessive build up.

9) Parts will be tack free after approximately 35 minutes.

10) Parts will be partially cured after 24 hours. Full cure and hardness does not take place until 5 to 6 days after application.

11) Finished goods may be shipped after 24 hours.

12) Clean tools and equipment with acetone or xylene.


Always spray coating in a well ventilated area or use a NIOSH approved self contained breathing apparatus or vapor filters on a mask. Protective gloves and safety glasses must be worn at all times. Only very high abrasion will remove the coating. Caution: With the extreme adhesion characteristics of this product all safety procedures must be followed. Be aware of over-spray so it will not land on any item that is not to be coated.
