MULTITEK™ PUMP FLUSH
Flushing Solvent for Polyurethane Dispense Equipment
Product Description
Special purpose, non-flammable, phthalate free, solvent material for flushing and short term storage of polyurethane/polyurea dispense equipment. MULTITEK™ PUMP FLUSH has excellent solubility with polyurethane and polyurea raw materials and full compatibility with GCP polyols, polyamines and isocyanates.
Product Uses
MULTITEK™ PUMP FLUSH is ideally suited as an effective solvent for removal of unreacted, liquid polyurethane and polyurea raw materials from dispense and spray equipment. It quickly flushes residual polyol and isocyanate from pumps, metal components, and rubber or polymer hoses, dispense heads and impingement mix spray guns.
MULTITEK™ PUMP FLUSH is typically used for flushing and short term storage of dispense equipment and as a flushing material when changing between polyurethane systems
Features
MULTITEK™ PUMP FLUSH is a non-toxic, non-hazardous solvent flushing material containing no harmful phthalate based compounds.
It is designed as a safe effective replacement for traditional flushing fluids such as DOP and other phthalate plasticisers.
This material is an excellent solvent for polyol, polyamine and isocyanate materials commonly encountered in polyurethane and polyurea processing. It is also safe for contact with most metals, rubbers and polymers encountered in dispense equipment.
- Simple, effective use for equipment flushing
- Will not damage O-rings, seals or seats
- Offers mild lubrication to pump components
- Non-hazardous and non-dangerous goods
- Non-flammable
- Non-corrosive toward most metals
Application Guidelines
This product is designed for use at ambient temperatures. Dispense equipment heaters are not required during flushing operations.
Use only clean, dry MULTITEK™ PUMP FLUSH that has been stored in a well-sealed container.
Place transfer pumps into pails of MULTITEK™ PUMP FLUSH or add MULTITEK™ PUMP FLUSH to emptied dispense machinery component tanks.
Recirculate MULTITEK™ PUMP FLUSH through the machinery system and fully flush material lines and dispense head/spray gun until clean MULTITEK™ PUMP FLUSH emerges.
Important – Never allow polyol contaminated MULTITEK™ PUMP FLUSH to be used for flushing the isocyanate side of dispense machinery, or vice versa. Cross-contamination will result in polyol-isocyanate reaction and can cause blockage of hoses, pumps and dispense heads or spray guns.
After full flushing is complete, repeat the flushing process using clean, dry MULTITEK™ PUMP FLUSH. MULTITEK™ PUMP FLUSH may remain in the equipment for short periods of time – up to 1 month. If longer term equipment storage is required, repeat the flushing process after 1 month using MULTITEK™ PUMP STORE.
Clean up
Clean up liquid leakage or spills using rags or other absorbent material. Final cleaning can be achieved using solvents such as MULTITEK™ XYLENE, MEK or acetone or using warm soapy water.
