Which putty is used for powder coating? — A practical guide to choosing the right putty for powder coating applications
Choosing the right putty for powder coating is one of the small — but crucial — decisions that determines whether a repaired part survives the high temperatures and rigorous finish requirements of a powder coat process. So, which putty is used for powder coating? In short: you need a high-temperature, oven-stable filler specifically formulated for metal substrates and for the thermal cycle used in powder curing. Generic fillers designed only for air-dry or low-heat refinish work will often fail in powder coating ovens, causing cracking, discoloration, bubbling or poor adhesion. That’s why “putty for powder coating” must be selected with heat resistance, adhesion, and thermal stability as the top priorities.
Industry background — what to look for in a putty for powder coating
Powder coating involves applying a dry polymer powder electrostatically to a metal surface and then curing it in an oven at temperatures commonly ranging from 160°C to 220°C — and sometimes higher for specialty powders or short-cycle processes. A putty intended for use prior to powder coating must therefore be able to withstand the oven cure without degrading or causing finish defects. Key technical attributes to check include:
• Oven stability up to the specified cure temperature (no softening, bubbling, outgassing or decomposition).
• Excellent adhesion to bare metal and to typical pre-treatment layers.
• Low shrinkage and high thermal tolerance to avoid cracking along edges or welds.
• Good filling and flow characteristics so repairs can be feathered and sanded to a consistent profile before coating.
• Compatibility with two-component (2K) systems and recommended hardeners for predictable pot life and curing.
When you ask “Which putty is used for powder coating?”, the correct technical answer is: a premium high-temperature, oven-stable filler engineered for metal substrates and formulated to withstand powder-coating ovens. In short — choose a dedicated high-temp filler, not a standard 1K or general-purpose filler.
SYBON’s solution: SY017 High Temperature Filler — the putty for powder coating
SYBON’s SY017 High Temperature Filler is designed specifically to be the putty used for powder coating. It’s engineered as the ultimate solution for surface finishing prior to powder coating and offers features that directly address the common failure modes in oven-cured finishes:
• ULTIMATE SOLUTION FOR YOUR SURFACE FINISHING PROCESS PRIOR TO POWDER COATING.
• Oven-stable repair putty formulated for metal substrates.
• Specifically developed for pre-powder-coating preparation — exceptional filling, adhesion and thermal stability.
• Guarantees no cracks, bubbles or color variation during oven cure up to 280°C.
• Two-component formula — used with hardener for reliable cure and performance.
Because SY017 is engineered to remain stable through high-temperature cures (up to 280°C), it helps eliminate the common risks of post-cure failure: outgassing, edge lifting, color shifts in the powder coat, and adhesion loss. It sands well, fills consistently, and bonds strongly to metal — which means less rework and a more consistent final finish.
Why distributors, agents and repair shops should care
Better choices go beyond price and specification. For agents and distributors looking for a competitive, high-margin product, SY017 presents an opportunity to offer customers a specialized putty for powder coating that performs like premium international brands but with a strong cost-to-performance advantage. For body shops, fleet owners and repair centers, selecting a putty for powder coating that behaves predictably in the oven reduces rework, improves throughput, and strengthens customer satisfaction.
SYBON vs. the big brands — a pragmatic view
SYBON may not always have the same global brand recognition as the largest multinational suppliers, but in many cases our SY017 quality is comparable while offering significantly better value. If your local market struggles with the high price of big-name fillers — or you need a supplier who can provide responsive service, flexible packaging, and sample support — SYBON is positioned to be a practical and reliable partner. Our goal is to provide performance that helps you compete locally while protecting your margins.
Who should consider SY017?
Automotive body filler distributors, refinish stores, fleet maintenance managers, collision repair centers, industrial coaters, and metal fabricators who use powder coating — anyone who needs a dependable putty for powder coating that won’t cause oven-cure failures should test SY017.
