A The substrate must be flat, dry, and clean (free of oil stains); it is recommended that the flatness tolerance be kept within 2mm. We advise using a dedicated keel framework for installation rather than direct adhesive bonding to ensure the long-term stability of the panels.

A Routine cleaning requires only a soft cloth dampened with a neutral detergent to gently wipe the surface. The use of strong acids/alkalis, abrasive cleaners, or steel wool is strictly prohibited to avoid scratching the protective surface coating.

A During the manufacturing process, we utilize fully automated continuous roller-coating and spraying techniques to ensure that color variations between production batches remain within controllable limits. In the event of surface damage, we do not recommend attempting DIY touch-ups; instead, please contact the supplier to obtain specialized repair paint or to arrange for panel replacement, thereby ensuring the integrity of the overall aesthetic finish.

A Delamination is typically caused by uneven adhesive application, adhesive aging, or improper compression ratios during bonding. Huaru Honeycomb employs aviation-grade hot-melt adhesive films combined with a high-temperature, high-pressure curing process. By strictly controlling these manufacturing parameters, we can fundamentally guarantee the interlayer bonding strength and service life of our composite panels.
