Oracover Oratex Bonding Emulsion 100mI

Secure a structural bond on the most challenging surfaces with Oracover ORATEX Bonding Emulsion (100ml). While standard ORATEX fabric comes with a high-quality heat-activated adhesive, certain airframe materials—such as highly porous balsa, oily hardwoods, or complex composite surfaces—require an extra "anchor" to ensure the fabric remains permanently attached. This water-based emulsion serves as a powerful surface primer that penetrates the substrate to create a high-tack interface, preventing the fabric from lifting even under the high tension of extreme shrinking.

Key Features:

• High-Strength Anchoring: Specifically engineered to increase the peel strength of ORATEX fabric, making it indispensable for high-performance aerobatic models and large-scale warbirds.
• Porosity Sealer: Fills the microscopic "valleys" in wood grain, providing a uniform bonding surface that prevents air from being trapped (the primary cause of bubbles).
• Safe & Low Odor: As a water-based emulsion, it is environmentally friendly and easy to apply in enclosed workshop spaces without the need for heavy respiratory protection.
• Optimized for Detail Work: Perfect for priming wing leading edges, rib caps, and tail feathers where the highest mechanical stress occurs during flight.
• Thermal Synergist: Works in tandem with the adhesive already on the ORATEX fabric; when the iron heat is applied, the two layers fuse into a single, vibration-resistant bond.

Builder's Application Tip:

For the most professional results, apply a very thin, even coat using a high-quality sponge brush or a lint-free cloth. It is vital to let the emulsion dry completely (until it turns from milky to transparent) before you begin the ironing process. If you iron over wet emulsion, the resulting steam can cause the fabric to "balloon" or prevent the adhesive from setting correctly.
