APT Polyester Tape with Silicone Adhesive — High Temperature 3.5 Mil, 1–2 in × 72 yd, Powder Coating & E-Coating

Meet the APT Advanced Polymer Tape, a premium masking solution built for demanding finishing tasks. This tape pairs a conformable polyester backing with a high-temperature silicone adhesive, engineered to stay strong during handling and to remove cleanly through bake cycles up to 200°C. With a 3.5 mil thickness and 216 ft (55 m) per roll, it reduces the frequency of roll changes while helping you maintain precise paint lines on challenging surfaces. The combination resists curling, shrinking, and edge lift, delivering sharp boundaries even on complex part geometries. In addition, the formulation prioritizes safety and compliance, aligning with RoHS and REACH standards and conforming to ASTM D-3652 performance benchmarks for dependable masking across applications.

Why choose APT Polyester Tape

Built for masking accuracy and reliable performance, this tape is designed to endure heat intensive finishes while keeping surfaces clean. The resilient backing helps prevent tearing during removal, and the silicone adhesive is formulated to minimize residue on coated areas. The result is a masking option that supports consistent results from start to finish.

• Extra strong backing — premium polyester film provides about two times the strength of standard films, reducing flaking and breakage when you remove the tape.
• High temperature, clean removal — silicone adhesive resists bake temperatures up to 200°C with minimal residue.
• 25% more free length — 216 ft (55 m) per roll means fewer roll changes on longer runs.
• No shrinking, curling, or lifted edges — preserves a sharp paint line and straightforward removal.
• Safety and compliance — RoHS & REACH compliant; tested to ASTM D-3652 for high-performance masking.

Practical applications and use cases

• Powder coating masking on automotive panels, housings, and interior components where heat is involved.
• E-coating masking needs to protect edges and interfaces without leaving residue.
• Protective masking on metal and plastic parts during paint bake cycles or curing processes.
• Masking for intricate shapes or edge work where a crisp line is critical.

Usage tips

For best results, apply to clean, dry surfaces and press out air to prevent trapped bubbles. Remove during or after bake cycles as recommended for your coating system. This tape’s 25% longer length reduces interruptions, while its strong backing helps maintain position during application.
