1#Pearl Cotton Hot Melt Adhesive

Pearl cotton hot melt adhesive is specially designed for bonding expanded polyethylene (EPE) foam, commonly known as pearl cotton. It provides strong adhesion, high flexibility, and excellent durability, ensuring reliable bonding in packaging and protective material applications.

The adhesive melts quickly at moderate temperatures, spreads evenly on EPE surfaces, and forms long-lasting bonds. It also features good temperature resistance, water resistance, and chemical stability, preventing delamination or bond failure during use.

This product is 100% solid, solvent-free, low odor, and environmentally friendly, meeting RoHS and REACH standards.

Instructions for Use

Preparation
- Ensure the bonding surfaces are clean, dry, and free of dust or oil.
- Use a hot melt adhesive machine or spray equipment with adjustable temperature.
Melting
- Add adhesive into the melting equipment and heat to the recommended operating temperature.
- Maintain stable heating to ensure consistent viscosity.
Application
- Apply molten adhesive evenly on EPE or bonding substrates.
- Quickly press and align parts together to achieve firm bonding.
Curing
- Allow adhesive to cool and solidify naturally under pressure.
- Avoid moving parts before complete curing.
Notes
- Avoid overheating to prevent adhesive degradation.
- Keep the working environment ventilated and dry.
- Store adhesive in a cool, dry place away from moisture and sunlight.
