Introduction

Heat transfer powder coating (also called sublimation powder coating) is a special base coat that accepts patterns transferred from transfer paper or film under heat and pressure. The design sublimates into the film, delivering wood-grain, marble, stone and other high-resolution decorative finishes on metal — combining powder durability with custom graphic printing.

Why Choose Heat Transfer Powder Coating

High-Resolution Decoration

Wood-grain, marble, stone and any custom graphic — the pattern sublimates into the film, not printed on top, so it keeps powder-grade durability.

Full Metal Durability

A smooth, consistent surface that resists scratching, fading and wear — the decoration is fused into the coating itself, so it cannot peel like a sticker.

Aluminum, Steel & Iron Compatible

Works on flat and shaped metal parts across automotive, appliance and consumer-goods work — with a range of colours, textures and finishes.

Sharp Branding & Detail

Rich colours and crisp detail for branding, product decoration and decorative parts — combining powder performance with unlimited print design.

Application Areas

Heat transfer powder coating serves furniture, general industry and architectural construction — anywhere a metal part needs a printed, powder-durable finish.

Furniture

Wood-grain metal furniture, lighting and handrails with a realistic, scratch-resistant printed finish.

General Industry

Flooring, fencing, shutters and signage — durable finishes that survive outdoor weathering and daily wear.

Architectural Construction

Advertising objects and decorative architectural parts with rich colours and crisp printed branding.

How Heat Transfer Works

Apply and cure the base coat — electrostatic spray, cured normally at 180–200°C for 10–15 min.
Fix the transfer paper/film to the coated surface.
Sublimate the pattern — bake the workpiece at 180°C for about 2 minutes so the inks sublimate into the film.
Peel off the paper to reveal the finished pattern.

Pretreatment cleans and protects the metal against corrosion and weathering — a necessary step for a durable finish. Base coat is applied by electrostatic spray and cured per the TDS; polyester or polyurethane systems are solvent- and heavy-metal-free. Decoration wraps the part in the printed film, vacuum-seals it, and uses heat and pressure in the transfer oven to drive the inks into the powder film; the exhausted film is then removed.

Heat transfer powder coating result

Practical note: the base coat colour and finish decide how the transferred pattern looks — light, smooth, dense films take sublimation ink best; textured or dark bases mute the print. Match the transfer-paper grade and oven profile (temperature, vacuum, time) to both the powder and the part geometry, and test on off-cuts first: under-baking leaves weak, rub-off-prone prints; over-baking can distort the film or shift colours. Edge wrapping and venting matter on deep or boxy parts, where air pockets lift the film and leave unprinted patches.
