PVDF Fluoropolymer PPGL Coil

PVDF Fluoropolymer PPGL Coil is prepainted 55% aluminum-zinc alloy-coated steel using a premium fluoropolymer coil-coating family commonly considered for ultraviolet and color-retention demands; resin content, pigment, primer, film build and forming limits must be specified for the exact system.

Specifications and dimensions

State whether thickness is base-metal or finished coated thickness, plus width, tolerances and edge condition.
State coil inside diameter, maximum outside diameter or mass, winding direction, camber and telescoping limits.
Define pretreatment, primer, top-coat and back-coat dry-film thickness, color, gloss, texture and protective film.

Standards and supply condition

ASTM A792/A792M-25a for the ordered 55% aluminum-zinc alloy-coated steel substrate
ASTM A755/A755M-18(2024) for applicable exterior building prepainted metallic-coated sheet
BS EN 10169:2022 for applicable continuously organic-coated steel flat products

Manufacturing and processing

The metallic-coated substrate is cleaned and pretreated before primer, finish coat and back coat are roll applied and oven cured.
The coated strip is cooled, inspected and recoiled, then may be slit, filmed or roll formed under controls that protect the coating.

Typical applications

Architectural façades and high-visibility cladding
Prestige roofing and long-exposure building envelopes
Coastal or high-ultraviolet projects after complete system qualification

Quality and acceptance controls

Verify substrate grade, heat or coil identity, metallic-coating designation and coating mass against the certificate.
Measure primer, top-coat and back-coat dry-film thickness using the agreed method and sampling plan.
Check color difference, gloss, texture, surface appearance and batch consistency against approved references.
Confirm adhesion, T-bend or flexibility, impact resistance and pencil hardness where required by the order.
Specify salt-spray, condensation, ultraviolet or chemical-resistance testing only with method, duration and acceptance criteria.
Inspect edge condition, winding, marking, protective film and moisture-resistant export packing.

Include in your RFQ

Substrate grade and governing metallic-coated steel standard
Metallic-coating type, designation and coating mass
Named organic coating system and supplier product where approval is required
Pretreatment, primer, top coat, back coat and each dry-film thickness
Color standard, color tolerance, gloss, texture and visual reference
Thickness basis, width, tolerances, coil geometry, edge and quantity
End use, exposure environment, corrosivity, ultraviolet level and design life
Forming profile, minimum bend, protective film and downstream process
Test methods, inspection documents, approved sample and warranty terms
Packing orientation, moisture protection, destination and delivery schedule

Selection limits

A resin-family label alone does not define formulation, pigment, primer, back coat, film build or verified performance.
No universal warranty or service life follows from PE, SMP, HDP or PVDF naming; use the named supplier system, exposure conditions and written warranty.
PPGI and PPGL are not automatic substitutes; cut edges, fasteners, condensation, alkaline contact and underside exposure require project review.
Color and gloss can vary with pigment, batch, film thickness, measurement geometry and weathering, so approval samples and tolerances must be explicit.
