Technical Engineering Deep-Dive

Engineered Specifically for Automotive & Marine Coatings

Automotive custom painters, OEM finish formulators, and fiberglass marine boat builders require flakes with extreme chemical resilience and outdoor durability. Standard craft glitters disintegrate in aggressive 2K polyurethane clears and fade to dull silver under UV solar exposure within months.

MLM Cosmetic manufactures true automotive-grade metal flakes utilizing high-purity optical polyester film coated with 99.99% vacuum-metallized aluminum and double-sealed with an aliphatic polyurethane UV-inhibitor barrier. Our flakes provide dazzling multi-angle sparkle for hot rods, lowriders, motorcycles, bass boats, and powder-coated wheels.

Lab Formulation Guide

Recommended Formulation Dosing & Carriers

Spray application and mixing ratios for automotive painters and marine composite builders:

Automotive Basecoat / Intercoat Clear

15g – 35g per sprayable liter
Ideal Cut: 1/500" – 1/128" (50μm – 200μm)
Carrier / Base: 1K / 2K Clear Basecoat (Intercoat Clear)
Formulator Pro Tip:Spray at 22-26 psi with 50% overlap. Flakes lay flat, requiring only 2-3 coats of 2K urethane clear.

Marine Fiberglass Gelcoat (Bass Boats)

60g – 120g per liter of clear gelcoat
Ideal Cut: 1/64" – 1/24" (400μm – 1000μm)
Carrier / Base: Isophthalic / Orthophthalic Polyester Gelcoat (MEKP catalyst)
Formulator Pro Tip:Resistant to styrene monomer. Spray directly into mold before fiberglass chopper layup.

Electrostatic Powder Coating

2.0% – 5.0% dry blend ratio
Ideal Cut: 1/500" – 1/256" (50μm – 100μm)
Carrier / Base: Clear TGIC Polyester / Polyurethane Powder
Formulator Pro Tip:Withstands 200°C–220°C oven cure cycle for 20 minutes without color fading or cloudiness.

Dry Flake Gun Application

Dry Flake Broadcast into wet clear
Ideal Cut: 1/64" – 1/24" Chunky Hex Flakes
Carrier / Base: Wet 2K High-Solids Clearcoat
Formulator Pro Tip:Spray dry flakes using 15 psi air over wet intercoat clear for maximum flake density.

Technical Questions

Frequently Asked Formulation Questions

Expert answers from our chemical engineers and regulatory specialists.

Q1.Will these flakes pass through a standard 1.3mm or 1.4mm HVLP spray gun?

Our 1/500" (50μm) and 1/256" (100μm) Micro-Flakes pass effortlessly through standard 1.3mm-1.4mm basecoat guns without clogging the nozzle or fluid tip.

Q2.How do you prevent the flake from sticking up and causing a rough sandpaper texture?

Our flakes are cut from ultra-thin 15μm-25μm film with high surface wetting tension, allowing them to lay completely flat on the panel so you need fewer coats of 2K clear to achieve a glass-smooth finish.

Q3.Can this flake withstand the high heat of electrostatic powder coating ovens?

Yes! Our automotive flakes withstand oven bake temperatures up to 220°C (428°F) for 20-30 minutes, making them ideal for dry-blending into clear powder coats for alloy wheels and metal fabrication.

Q4.Is the glitter resistant to harsh automotive solvents and reducers?

Yes. Our aliphatic polyurethane barrier coating is 100% resistant to polyurethane thinners, xylene, acetone, MEK, and polyester gelcoat styrene.
