MULTITEK™ METAL PARTS CLEANER

Product Description

Special purpose, non-flammable, solvent material for removal of cured polyurethane, polyurea and other thermosetting polymers such as epoxy.

Product Uses

MULTITEK™ METAL PARTS CLEANER is suitable for the simple removal of cured polyurethane / polyurea residues from dispense equipment components such as pumps, dispense and spray heads etc. It allows “contact-less” cleaning of delicate, precision machined metal components such as impingement nozzles and mix chambers.

This reduces wear and the occurrence of mechanical damage to these parts often caused by cleaning with drill bits, scrapers or cleaning wires. Chemical cleaning ensures that precision orifices retain their dimensions and remain damage and score free for as long as possible, helping to maintain accurate and trouble free dispense machine operation.

MULTITEK™ METAL PARTS CLEANER is typically used hot for rapid cleaning. It is also effective used cold, though cleaning processes will take days instead of minutes or hours.

Features

MULTITEK™ METAL PARTS CLEANER is an easy to use cleaner suitable for cleaning parts at ambient temperature if required, or for more efficient, rapid cleaning it can be heated to 80°C.

MULTITEK™ METAL PARTS CLEANER is suitable for cleaning all ferrous and non-ferrous metals, plus polymer materials having high chemical resistance such as fluoropolymers, polyethylene, polypropylene, nylon etc.

Important – MULTITEK™ METAL PARTS CLEANER is not suitable for cleaning polymer or rubber O-Rings, seals or gasket materials such as Buna N rubber, neoprene, silicone or Viton®.

• Simple, effective use for metal parts cleaning
• No damage “contact-less cleaning”
• Quickly breaks down polyurethane/polyurea
• Non-flammable
• Use hot or cold if preferred
• Non-corrosive toward most metals

Storage

MULTITEK™ METAL PARTS CLEANER should be stored between 15°C and 25°C. Drums must remain tightly sealed against moisture ingress. Under these storage conditions these materials will have a shelf life of 6 months. Storage at temperatures other than detailed can result in degradation of the product, rendering the materials unusable. Ingress of humidity or water into the drums during storage or use will also make the materials unusable.

Application Guidelines

Elevated Temperature Use

Heat MULTITEK™ METAL PARTS CLEANER in a temperature controlled vessel such as an electric frying pan or hot chip cooker. The frying pan must be porcelain or Teflon® coated. Do not use a pan made out of temperature resistant plastic as the MULTITEK™ METAL PARTS CLEANER will probably dissolve it.

Safety glasses, protective clothing and chemical resistant gloves must be worn when using this cleaner. Use great care when handling heated cleaner. Use chemical resistant tongs to add or remove parts from the cleaner.

Half fill the pan with MULTITEK™ METAL PARTS CLEANER. Set the pan thermostat to 80°C and heat the cleaner. If they are to be reused later, remove all rubber like seals and O-rings from the part to be cleaned, as the MULTITEK™ METAL PARTS CLEANERwill dissolve or swell these materials.

Completely immerse the part in the cleaner and allow to soak until the polyurethane residue softens to a gel. This may take 10 to 30 minutes depending on the amount of residue present. When softened, the gel can be flushed, brushed or shaken away. Compressed air may also be used to blow clean parts, narrow ports etc. Any remaining residue can be removed by further soaking in the cleaner.

Once clean, allow the part to cool completely. MULTITEK™ METAL PARTS CLEANER residue can be rinsed from the part using common solvents such as water, acetone, Multitek MEK, MULTITEK™ XYLENE. MULTITEK™ METAL PARTS CLEANER can be reused time and again until it becomes a dark brown colour and loses dissolving power.

Large components may be cleaned by soaking cotton cloth in warm to hot MULTITEK™ METAL PARTS CLEANER and draping the soaked cloth over the component.

Ambient Temperature Use

When using at ambient temperature, follow the same use and handling precautions. Simply use without heating. Softening of residues by this method may take several days depending on the amount of residue present.

Disposal of Used MULTITEK™ METAL PARTS CLEANER

Used cleaner may be disposed of by an approved chemical waste removal agency. Alternatively, the used cleaner can be allowed to solidify as water etc. evaporates from the liquid over a period of 1 – 2 weeks. When solid, the residue which is largely solidified polyurethane, may be disposed of as nonhazardous solid industrial waste.

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.

Health and Safety

Operators must have full awareness of the material safety requirements before any work is undertaken.

While MULTITEK™ METAL PARTS CLEANER is a non-hazardous material, contact with skin or eyes should be avoided as a matter of good practice.

Preventative PPE should be worn when handling MULTITEK™ METAL PARTS CLEANER and it should be used in areas with adequate ventilation. Required PPE includes butyl or nitrile gloves, safety goggles or full-face shield, coveralls and chemical resistant safety boots. A half or full face respirator fitted with suitable organic vapour filters should be worn if this product becomes atomised during use.

In case of spills and accidents, refer to the MSDS of the products or when in doubt contact your local GCP representative.
