- Operating Conditions
- Can be applied by slot coater or teflon coated roll coater adapted for reactive hot melts at material temperature of 250 - 275°F.
- Drum and pail unloaders may be set to melt temperatures of between 230°F and 240°F.
- Hose settings should be the same as the platen setting (never hotter to avoid burning the adhesive in the hose.)
- Typical applicator temperature is 245°F to 255°F. Temps up to 275°F may be used if desired and will include appropriate increase in platen and hose settings.
Note: Never heat above 300°F. Use only in equipment intended for reactive hot melts. Do not use in conventional hot melt equipment. Forced ventilation must be provided over applicator and melting equipment to remove any small amount of isocyanate vapors from the work area. All users of RHM products should maintain an ongoing industrial hygiene program. This program should include contingency provisions in the event of ventilation failure as well as MDI monitoring.
- Cleaning Information
Flush system by running Purmelt Cleaner #2 through equipment. Do not allow Technomelt PUR 3365 to cure on equipment. Cured adhesive requires special solvent for removal (e.g., n-methyl pyrrolidene). Read MSDS for NMP before using.

Safety & Health
- Safety Precautions
- Read material safety data sheet before using this product.
- Technomelt PUR 3365 is a product which contains minor amounts of organic isocyanates. Health hazards have not been fully evaluated.
- Never heat above 300°F.
- Use only in equipment intended for reactive hot melts.
- Do not use in conventional hot melt equipment.
- Forced ventilation must be provided over applicator and melting equipment to remove any small amount of isocyanate vapors from the work area.
- Rotate stock and use oldest material first.
- Do not expose to the atmosphere or otherwise contaminate with moisture.
- Moisture contamination will cause a sharp viscosity increase or gelation (curing)
- Containers must be used completely after opening. Do not attempt to reseal.
- Do not heat to melting without proper forced ventilation.
- Vapor is harmful if product is overheated (excess of 300°F).
- Prevent breathing of vapor.
- Prevent contact with skin.
- Do not take internally.
- Material is applied hot. Appropriate clothing and eye protection should be used to prevent severe burns.
- Do not mix with other materials except to flush system as noted above.
- Use only with adequate ventilation.
