Because there is no chemical bonding between thermoplastics and substrates. The lack of bonding means low adherent, it makes 1K aerosol paints unacceptable for industrial coating standards. Since thermoplastics used are dissoluble in many solvents. The coatings formed by 1K aerosols are re-dissoluble by many solvents. Other properties, such as chemical resistance, weathering resistance, mechanical strength, etc., are very poor.

ADVANTAGE of 2K AEROSOL PAINTS

2K aerosol are based on two parts of components. The polymer component and crosslinker component. After mixing the two components react to form cross-linked macromolecules under the action of catalysts. The cross-linked macromolecules have superior properties comparing to thermoplastic lacquers in 1K aerosols. The reactive components in the 2K system  provide strong chemical bonding between macromolecules and substrates. The properties of 2K enamels do not depend on molecular weights of original polymer or molecular weight of cross-linker. Therefore, both components can be low molecular weights. High solids 2K aerosol paints are possible for 2K aerosol paints. For example 40-60% solids of 2K aerosol paints can be prepared. One bottle of 2K aerosol paints is equal to 10-20 bottles of 1K aerosol paints.

ADVANTAGE of FLUORO-URETHANE

The 2K fluoro-urethane has the best weathering, chemicals, solvents, microbial, and mildew resistance.

High percentage of fluorine contents of fluoro-urethane with highest strength of fluorine-carbon bonds provides weathering, UV, and chemical resistance.

Low surface energy, chemical resistance, water and oil repellence provides excellent stain resistance and self-cleaning properties.

2K fluoro-urethane uses polyisocyanate as cross-linker with very low concentration of free isocyanate. Polyisocyanate is isocyanate free polymer material. Common urethane formulations use a polyisocyanate with low concentration isocyanate, or isocyanate for higher rate of cross-linking.  Free isocyanate  put applicators in a hazardous environment, which is dangerous due to toxic isocyanate presence. 2K aerosol fluoro-urethane eliminate low concentration of free isocyanate during activation and mixing processes when all chemicals are still in the 2k aerosol can. During spray process ther is no free isocyanate. 

Cross-linked fluoro-urethane bond network provides chemical resistance, and mechanical strength.

Water repellence and oxygen barrier properties provides excellent corrosion protection for coated metals.

Excellent electric properties on volume resistances, dielectric strength, and low dissipation are beneficial for electronic coatings. 

Fluoro-urethane provides water repellence and wet non-skid surfaces for bare foot contacts.

Broad optical transparency provides the brilliant color. By comparison, thermoplastic non-transparent fluoropolymer, such  PVDF (Kynar 500), is lack of gloss. 

Non-combustible and heat resistance provides ideal surfaces for contact with hot substances.

Low fraction coefficient and high mechanical strength provides abrasion, and wear resistance.

Graffiti, tar and 1 K paints on the surfaces can be cleaned with detergent water or solvent wipe.

Mildew and mould can not grow on fluoro-urethane surfaces.

Dirt, bugs, fuel residue, pollutants, tree sap, and pollen will not able to stick to the coating.

Salts, acid, alkali, fuel, coolant, lubricating oil, break fluid, grease, wax will not effect coated surfaces. Those pollutants can be removed with detergent water.

APPLICATION of 2K FLUORO-URETHANE AEROSOL PAINTS

Luxecolor 2K aerosol paints combine the best paint material, 2K fluoro-urethane, with aerosol application convenience.

2K fluoro-urethane can be applied on any solid surfaces: metals and alloys, such as iron, steel, aluminum, zinc,  bronze, stainless steel, ceramics, porcelains, glass, thermoplastics, nylon, polycarbonate, epoxy, acrylics, polyesters, plastics, rubber, wood, paper, clothing, lather, wool, wires, PCB boards, and many other solid materials.   

A primer is required only when a build-up surface is involved.

Versatile formulations are possible.

Followings are some professional and home applications:

Proper cleaning of substrate is required. Surface must clean, without any loss rust, silicone, grease, oil, wax and other contaminates.

If no oil, grease, or silicone contamination, even a rusted metal can be painted directly by simple remove loss rust with sand paper.

For contaminated surfaces use medium concentrate detergent to remove grease, wax and other contaminants (silicone require polychlorinated solvent to clean it up) ; Use water and clean sponge to thoroughly wash detergent off ; Sanding with #200, #400, and #600 sand paper, Rinsing with clean water, Dry with lint-free and clean cloth; Allow surface dry completely; Prime bare metal with 2 K primer; and Mask surrounding area.

HOW TO USE 2K AEROSOL

Activate and mixing 2 K components is a critical step: (1) Rotate aerosol can to familiarize the sound of a vial colliding with the aerosol can; (2) Firmly hold aerosol can with stretch arm, risen to higher position and suddenly pulling down with fast movement to beak a vial, it may repeat several times; (3) Rotate the aerosol can to check collision sound, if broken glass with free rolling ball can be heard, go to next step, otherwise go back to step 2;  (4) Shake aerosol can for 5 minutes to mixing 2K component.

Application: Target the nozzle 4-8 inch distances with slow, even strokes. Spray "wet" coat, Allow 15-20 second spray second coat. Tack free time is 5-10 minutes, cure time is 6-8 hours. 2 K aerosol should used up in 8 hours after activation. After 8 hours, the aerosol formation becomes difficult. 

Preparation: Checking color match carefully. Rub with xylene to test surface before spray. If surface become soft or lifting with orange shape skin. thorough remove this area until see bare metal. Use 2 K primer to cover bare metal.

Luxecolor aerosol is equipped with a special nozzle to emit a fan-shaped paint spray.

Luxecolor 2K aerosol contains approx. 340 grams of paint and with 40% solids which is enough for painting an area of 1 m2 or 10-12 square foot area.

Application Notice:

For high gloss surface using extra fine sending paper (400-600 grit) gently rub the surfaces and carefully remove the dust following by washing and dry.

Use tape, paper or insoluble plastic to protect any areas you do not want to paint.

Ensure adequate ventilation and use personal protective wear.

Paint 1 to 2 thin layers at a distance of 10-20 cm (4-8 inch) from the surface to be painted.

Let each layer dry for 15-20 seconds.

Clean the aerosol nozzle after painting by turning the can upside down and pressing the nozzle until only gas comes out. Remove any fresh splashes or defects.

The whole content in the aerosol can must be used during 8 hours after activation.

Luxecolor 2k aerosol paints contains butyl acetate, xylene, and MEK (methyl ethyl ketone) as a solvent. Our next step of development is to replacing butyl acetate, xylene, and MEK with non-hazardous solvents such as acetone, methyl propyl ketone (MPK), amyl methyl ketone, butyl propionate for environmental friendly porpose.

Luxecolor 2k aerosol paints are propelled by DME (dimethyl ether) gas, which does not harm the ozone layer. The paint spray is highly flammable and should never be used near open flame or glowing objects, or in places where static electricity could cause sparking or discharge. Smoking is prohibited where Luxecolor 2k aerosol paint is being applied.

Use Luxecolor products outdoors or only in adequately ventilated spaces. Always wear suitable protective face mask with organic vapor (active carbon) air cartridge, clothing, gloves and eye protection. Store aerosol cans in cool, ventilated area. When transported, keep automobile cool. Do not puncture used containers or dispose of by burning, even when empty.

Our new development is PFOS and PFOA free, micronized PTFE powder which is environmental friendly product.

On market all PTFE including Du Pont Tefron contain at least 200 ppm PFOA or PFOS.

PFOS, PFOA and other low molecular weight perfluoro surfactants are dangerous, bio-cumulative pollutants. Animal test showed they are carcinogen, and cause liver tumors in animals. Human population statistics shown that PFOS and PFOA increase breast cancers, birth defects, high cholesterol, and etc.. However, 95% of Americans, human including babies, of four continents, and animals all over the world have been contaminated with PFOA and PFOS. PFOA and PFOS have been accumulated in protein, liver, and blood.  For human, the main route is the anti-stain papers for food package and dust particles from anti-stain carpets, non-stick cooking ware, and food chains. All animal accumulate PFOA and PFOS from water and food chains.   

A new product, LuxeColor SS-1, is 2K aerosol stone sealer for granite surfaces. It contains micronized PTFE, and is PFOS and PFOA free.
