When working with high-performance double-sided tapes such as Stykra 650 and Stykra 700, achieving maximum adhesion is critical. Sign materials can vary in texture, porosity, and surface energy, which can sometimes limit the tape’s initial bond. This is where Stykra EXT Primer plays an essential role.
Benefits of Using Stykra EXT Primer
-
Enhanced Adhesion: The primer increases surface energy, allowing Stykra tapes to achieve stronger, more reliable bonds.
-
Improved Longevity: A well-prepared surface reduces the risk of tape failure, even in demanding outdoor environments.
-
Versatility Across Materials: Especially useful on low-energy or textured surfaces, where tape alone may struggle to adhere.
By using Stykra EXT Primer, sign makers ensure a more consistent, durable bond between substrates, reducing callbacks and improving customer satisfaction.
How to Apply Stykra EXT Primer
Follow these steps to achieve the best results:
-
Clean the Surface
-
Use Stykra EXT Cleaner, a suitable solvent cleaner and degreaser.
-
Thoroughly remove dust, grease, oils, and other contaminants.
-
Ensure the surface is completely dry before applying primer.
-
-
Apply the Primer
-
Use the supplied primer swab or a clean applicator.
-
Apply a thin, even coat over the bonding area.
-
Avoid pooling or over-saturation—less is more.
-
-
Allow to Dry
-
Let the primer dry thoroughly before applying tape.
-
Typical drying time is 30–60 seconds, depending on conditions.
-
-
Apply the Tape
-
Firmly apply Stykra 650 or 700 tape to the primed area.
-
Use pressure to activate the adhesive and ensure full surface contact.
-
-
Bond the Substrates
-
Position and press the materials together.
-
Apply consistent pressure across the bond line to maximize adhesion strength.
-
Pro Tips
-
Always test on a small area if unsure about compatibility.
-
Avoid touching primed areas with fingers before tape application.
-
Store primer swabs in a sealed pack until ready to use.
-
Work in a clean, dust-free environment for best results.
By integrating Stykra EXT Cleaner and Stykra EXT Primer into your workflow, you’ll achieve stronger, longer-lasting bonds with Stykra 650 and 700 double-sided tapes—especially when working with challenging sign substrates.
