PUR-6573 is a 100% solids, single-component polyurethane, reactive hot melt adhesive. This product is used for cloth to cloth purpose textile adhesive with excellent initial tack and bond strength. It works well for laminating fabric to fabric or fabric to foam. Once cured, the adhesive has the following properties:
* High peel strength
* Superior wash resistance
* Excellent dry cleaning resistance
* Thermal and chemical resistance
* High initial tack and bond strength
* Excellent viscosity stability at application temp
* Equipment friendly
Typical Physical Properties
Solid Content: 100%
Specific Gravity: 1.12
Viscosity @ 90 C: 17000 mPas
Film Open Time * : 5-8 minute

Film Open Time * 5-6 minute
Shelf Life (see Packaging section) 6 months
Contaminants like oil, dust, corrosion and dirt negatively affect the adhesion of any adhesive. Surfaces must be clean, dry and free from surface contaminants.
To obtain complete cure, this product should be exposed to temperatures and relative humidity conditions greater than or equal to 25C and 50% RH.
For adhesive film thicknesses 0.5 mm or less, cure is typically completed in 7 days under these conditions. Complete cure will take longer at lower temperatures and lower RH. Cure rates and completeness of cure will vary with adhesive film thickness and substrates' water permeability.
To clean spilled adhesive, allow the adhesive to cool to room temperature and scrape off heavy deposits with a putty knife. Any uncured residual film may be wiped clean with common polyurethane solvent ( MEK). Clean the adhesive before it cures. Cured adhesive can only be cleaned with extremely high heat (>425C) or an aggressive solvent such as heated N-methyl-pyrrolidone.
Packaging, Stability, and Shelf Life
PUR-6573 reactive hot melt adhesives are packaged and shipped in sealed, straight-sided 200KG drums and 20KG pails. Consult the equipment manufacturer for start-up, shutdown and cleanup procedures. If the equipment is to be shut down for extended periods of time, we suggest purging the system with our flushing agent. Partially used pails or drums should be purged with a dry, inert gas and re-sealed between uses.
WARNING: Moisture contained in the air or from wet surroundings will cure this adhesive. Cured adhesive cannot be re-melted and may cause equipment damage.
At application temperature in the absence of moisture, such as sealed melters and hoses, this adhesive will exhibit an increase in viscosity of less than 1% per hour. For optimal performance with roll-coating applications, We recommends a consumption rate such that the amount of melted adhesive on the rolls be consumed in under 45 minutes. Adhesive that remains on the rolls for extended periods of downtime (longer than 60 minutes) should be discarded and replaced with fresh adhesive.
To dispose of this adhesive, loosen the lid of the container to allow the adhesive to cure, then dispose of it compliance with state and local regulations. In most localities, empty pails or drums may be crushed and sent to a local landfill. Since local landfills have the right to refuse any material, check first.
Check with the local drum recycler to see if they will accept the empty drums for recycling. Check with local scrapping companies to see if they will accept empty drums or pails as scrap metal. Check the Material Safety Data Sheet for disposal requirements.
Health & Safety Precautions
Severe burns will result if skin contact occurs.
Wear appropriate gloves and long sleeve garments to protect from burns and skin sensitization. Wear protective eyewear to minimize the risk of eye contact. If skin contact occurs, immediately immerse contact area in cold, clean water for at least 30 minutes. Cover contacted area with a wet,clean compress, and see a physician immediately.
