Application Method

Typical Applications

Curing Conditions

To obtain complete cure, this product should be exposed to temperatures and relative humidity conditions equal to or greater than +77°F and 50% relative humidity.
For adhesive film thicknesses 0.020 inches or less, cure typically is completed in 7 days at +77°F and 50% relative humidity.
Complete cure of this product will take longer at conditions less than +77°F and 50% relative humidity.
Cure rates and completeness of cure will vary with adhesive film thickness and substrates' water permeability.

Application Instructions

Warning : Application temperature must not exceed 300°F. Fumes and particulates containing excess isocyanates may be generated.
This adhesive is designed to be used with platen or reservoir-type melters that will dispense adhesive from 5-gallon pails and 55-gallon drums.
This product is designed to have less than a two-fold increase in viscosity over 12 hours at normal application temperature in the absence of moisture.

Cleaning Instructions

To clean up 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 a common polyurethane solvent (Toluene, MEK).
Clean up adhesive before it cures.
Consult the equipment manufacturer for any cleanup procedures.

Safety Advice

Use this adhesive in a well-ventilated area.
Local exhaust ventilation should be provided at the point of application and over the pre-melting reservoir.
Monitor the level of free methylene bisphenyl diisocyanate in the operator’s work zone during application. OSHA regulations state that the maximum exposure of the operator should not exceed 20 parts per billion. The time-weighted average exposure over an 8-hour period should not exceed 5 parts per billion.
Wear appropriate gloves and long-sleeve garments to minimize the risk of burns and skin sensitization.
Wear protective eyewear to minimize the risk of eye contact.
