Silicone Splice and Platers Tape
Silicone Splice and Platers Tape is a single-coated high-tack silicone adhesive tape constructed with a 1.50 mil silicone adhesive on a 1.00 mil blue polyester carrier, for a total thickness of 2.50 mils. The controlled level of crosslinking in the adhesive provides a balance of substrate adhesion with chemical and temperature resistance, supporting service from −60°F to 350°F. Peel adhesion is 36 oz/in with 168 hours of shear hold at 2.2 psi, plus fine-line definition and clean residue-free removal — making it suitable for flash breaker, powder coating masking, and high-temperature splicing of silicone-coated materials.

For maximum adhesion, bonding surfaces should be clean, dry, and free from grease and oils. The firmer the application pressure and the greater the contact area, the stronger the bond. Bond strengths will increase as a function of time as the adhesive continues to wet out the bonding surfaces.
- Flash breaker tape for composite cure cycles where high-temperature edge masking is required
- Powder coating masking applications requiring oven-temperature resistance and clean line definition
- Splicing of silicone-coated papers, films, and textiles where standard adhesives cannot bond
- High-temperature masking in industrial coating, plating, and finishing operations
- Fine-line surface protection in processes requiring chemical and abrasion resistance
Common industries: Composites manufacturing, powder coating, electroplating, industrial finishing, silicone-coated material converting.
Silicone Splice and Platers Tape is a single-coated high-tack silicone adhesive tape engineered for high-temperature masking, splicing, and flash-breaker applications. The construction pairs a 1.50 mil silicone pressure sensitive adhesive with a 1.00 mil blue polyester (PET) film carrier, yielding a 2.50 mil total stack.
The defining design feature is the controlled level of crosslinking in the adhesive — calibrated to provide a balance between substrate adhesion strength on one side and chemical/temperature resistance on the other, with fine-line edge definition that prevents adhesive bleed and ensures clean residue-free removal after high-temperature processing.
The tape is well-suited for splicing silicone-coated papers, films, and textiles — applications where conventional acrylic and rubber tapes typically fail because they cannot bond reliably to silicone-treated surfaces. As a flash-breaker, it provides masking edge protection during composite cure cycles. As a powder coating mask, it withstands oven temperatures while leaving clean lines on the finished surface.
Service temperature spans −60°F to 350°F, with both abrasion resistance and chemical resistance rated affirmatively. Peel adhesion is 36 oz/in per PSTC-101, shear hold reaches 168 hours under a 2.2 psi load per PSTC-107, and tack is 22 oz per ASTM D2979. Tensile strength is 25 lb/in with 180% elongation. The TDS notes that bond strength increases as a function of time as the adhesive continues to wet out the bonding surfaces.
What differentiates Silicone Splice and Platers Tape from other high-temperature masking tapes?
The silicone adhesive chemistry is the defining differentiator. Standard acrylic and rubber masking tapes cannot bond reliably to silicone-coated papers, films, and textiles, but the silicone adhesive in this tape is specifically formulated for those substrates while also providing high-temperature resistance to 350°F. The controlled crosslinking calibrates adhesion strength against chemical/temperature resistance to deliver clean release without residue after extended exposure to oven cycles, plating chemistries, or composite cure conditions.
Why is peel adhesion important when selecting this tape?
For masking and splicing applications, peel adhesion must be high enough to maintain seal during processing but low enough to release cleanly without residue or substrate damage. The 36 oz/in value reflects this calibrated balance — sufficient to anchor through high-temperature processing while still permitting clean removal afterward.
What is the service temperature range for Silicone Splice and Platers Tape?
The tape has a service temperature range of −60°F to 350°F.
Is this tape suitable for chemical-exposed or abrasion-prone applications?
Yes. The TDS rates both chemical resistance and abrasion resistance affirmatively, supporting use in plating operations and other process environments where the tape may be exposed to aggressive chemistries or mechanical wear during application. No specific regulatory compliance standards are listed on the TDS for this material.
How should Silicone Splice and Platers Tape be specified?
Specify product (Silicone Splice and Platers Tape), adhesive thickness (1.50 mils), carrier thickness (1.00 mil polyester), color (Blue), target substrate (particularly noting any silicone-coated materials), processing conditions (oven temperature, chemistries), compliance requirements, dimensional tolerances, and finished format.
