Product Advantage
Delivers a powerful instant grab and wet-out upon contact, ensuring that heavy-duty wallpaper rolls or textured textile wallcoverings lock into place immediately without sliding.
Engineered with high internal cohesion (7,500 cps @ 160℃), generating massive destructive bond-lines that permanently resist heavy gravity peeling and corner lifting over decades.
Maintains highly stable viscosity curves under elevated heat, allowing automated processing lines to lay down perfectly uniform film weights without nozzle blockages or adhesive tailing.
Fortified with advanced synthetic chemical stabilizers to prevent dried glue films from turning yellow, brittle, or powdery under typical heat variations and ambient sunlight exposure.
Formulated to remain completely stable across humid indoor microclimates, shielding the wallpaper structural bond from delaminating or breaking down in moisture-prone rooms.
Thoroughly tested and verified safe by SGS environmental screening; releases ultra-low VOCs and zero harmful chemicals, aligning with global eco-friendly interior building codes.

FAQ
1. Q: Why is a balanced viscosity profile (7,500 cps @ 160℃) important for wallpaper coating?
A: Wallpaper line speeds demand absolute coat weight consistency. If the viscosity is too erratic, the adhesive layer becomes uneven, leading to dry spots or bulk adhesive oozing. It ensures a perfectly smooth fluid distribution via slot dies.
2. Q: Does this adhesive yellow or cause staining on premium thin paper backings?
A: No. Formulated from premium synthetic elastomers with high thermal stability, it resists chemical oxidation under sunlight and aging. It retains its clear, yellowish transparency without staining light-colored face sheets.
3. Q: Can this wallpaper hot melt adhesive survive high indoor humidity or moisture shifts?
A: Yes, absolutely. Unlike water-based starch adhesives that liquefy or grow mold when exposed to damp conditions, our 100% solid hot melt pressure-sensitive matrix is highly hydrophobic, ensuring the bond stays intact.
4. Q: What clean-up routine is suggested when transitioning coating lines?
A: To avoid destabilizing the high-performance tackifier matrix, flush your melting tanks with clean mineral oil at 120℃, then thoroughly purge the slot system with this exact same model below 170℃ before initiating a run.
5. Q: Is this interior wall adhesive safe for residential consumer markets globally?
A: Yes. Our formula has fully passed rigorous SGS environmental non-toxicity verification. It releases no harmful solvents, chemical odorous vapours, or toxic outgassings, making it completely compliant with EU and North American indoor material imports.
