Follow these steps to ensure optimal bonding strength and material performance.
Optimal Parameters
Preparation
Clean and dry bonding surfaces thoroughly. Ensure no dust, oil, or moisture remains on substrates like metal or foam.
Film Placement
For XJO115, arrange release liner upward. For XJO116, clamp directly between the two substrates.
Hot Pressing
Apply heat at 125–150℃ with 0.2MPa pressure for 10–30 seconds. Adjust based on substrate thickness and heat conductivity.
Cooling & Inspection
Remove liner only after complete cooling. Conduct peel strength verification to ensure quality control.
