What are the types of topcoats for GNEE color steel plates (color-coated steel coils)?

Topcoat types of GNEE color steel plate (color-coated steel coil):

In the coating of color steel plates, resins and pigments play a role in durability. Commonly used topcoats are polyester, silicon-modified polyester, high weather-resistant polyester, and polyvinylidene fluoride.

1. Polyester GNEE color steel plate: good adhesion, rich colors, wide range of formability and outdoor durability, medium chemical resistance, and low cost.

2. Silicon-modified GNEE color steel plate (SMP color steel plate): Silicon-modified polyester color steel plate, referred to as SMP color steel plate, can also be called wear-resistant polyester topcoat or wear-resistant color steel plate, using high-resistant nano-siliconization Resin formula, SMP silicone modification has excellent heat resistance and good wear resistance.

3. High weather-resistant GNEE color steel plate (HDP color steel plate): High weather-resistant polyester (HDP) uses high molecular weight resin. The polymer has few branches, stable bond energy, and does not photolyze, so it does not pulverize and reduce gloss. HDP uses ceramic pigments that will not fade in sunlight.

GNEE high weather-resistant color-coated boards provide a 15-year coating quality guarantee, ensuring that the coating will not fall off or powder within 15 years. Excellent durability and color retention properties.

4. Polyvinylidene fluoride GNEE color steel plate (fluorocarbon GNEE color steel plate, PVDF GNEE color steel plate): PVDF fluorocarbon coating is a first-class product among existing architectural coatings. The coating adopts a proprietary formula. GNEE PVDF coating suppliers have KYNAR500 and HYLAR5000 coating certification qualifications. These two brands are two world-famous PVDF manufacturers that require PVDF coatings produced by certified coating units to contain at least 70% PVDF resin (mass ratio). In order to ensure that fluorocarbon coatings have extremely high weather resistance, PVDF coatings The pigments used can only be high-temperature calcined metal oxide or metal oxide alloy pigments, that is, ceramic pigments; weather-resistant rutile titanium dioxide; acid- and alkali-resistant metal pigments and durable mica pearlescent pigments.

GNEE fluorocarbon coated color steel plate provides a 20-year coating quality guarantee, ensuring that the coating will not fall off, powder, flake, or discolor within 20 years.
