Cleaners having an organic solvent as a main component are commonly used to remove oil on a metal surface.
Although there are available pail can cleaners advantageous in cost, aerosol products are generally used for easy storage and handling.

However, this organic solvent cleaner has the following concerns:

• 1) Special care needs to be paid to the health of operators when being used.
• 2) Special care needs to be paid to storage.
• 3) Organic solvents may adversely affect plastic and rubber members.

DKD-1405 Contact Spray Cleaner has the following advantages:

• 1) It exhibits an excellent cleaning effect by a combination of special organic solvents.
• 2) It has reduced influence on plastic and rubber members due to optimum blending of alcohol, etc.

Cleaners using an organic solvent have the following concerns:

• 4) It may cause fire or explosion when being used for a high-temperature part, or a place where fire is used or sparks fly.
• 5) The cleaning effect thereof may be reduced due to volatilization of a solvent when being used for a high-temperature part.

DKD-9000 Nonflammable Spray Cleaner has the following advantages:

• 1) Unlike the case of using an organic solvent, there is no need to pay special care to the health of operators.
• 2) There is no need to pay special care also to the storage due to its nonflammability.
• 3) There is relatively less risk that a solvent adversely affects plastic and rubber members.
• 4) There is no risk of fire or explosion when being used for a high-temperature part since the solvent is noncombustible and a filling gas is a Co2 gas.
• 5) High cleaning power is exhibited for small parts due to small surface tension and high permeability of the solvent.
• 6) A load imposed on environment which may cause global warming, ozone layer depletion, and the like is extremely small.

When a metal surface is cleaned to remove oil and is left untouched afterward, rust may be generated. To prevent this, a rust preventing agent is used.

Although there are available pail can agents advantageous in cost, aerosol products are generally used for easy storage and handling.

Note: This product has permeability and lubricity in addition to rust prevention ability.

Besides these, there is available a rust preventing agent strengthened particularly in rust prevention ability, which is optimally used for a portion brought into contact with water for a long time, a portion where rust easily occurs, such as a welding portion, and for components stored outdoors.

Further, there is available a rust preventing agent having higher permeability and lubricity.
High permeability allows the rust preventing agent to permeate to finer components and the rust preventing effect to be exerted thereto, and blending of organic molybdenum further enhances lubricity, making lubricating effect long-lasting.

A contact rust preventing grease imparted with rust prevention ability is optimally used for electrical contacts and connectors.

This contact rust preventing grease has the following advantages:

• 1) It contains a component excellent in rust prevention ability.
• 2) It has reduced influence on plastic, resin, and rubber.
• 3) It has a reduced oil evaporation loss, is unlikely to be subjected to oxidative deterioration and solidification, and can thus function as lubricant for a prolonged period of time.

Note: Carry out tests without fail to check the influence of this product on plastic, resin, and rubber before actual use

A molybdenum disulfide silicone grease is optimally used for a portion needing higher heat resistance, higher cold resistance, or higher load resistance. This molybdenum disulfide silicone grease has the following advantages:

• 1) It is excellent in heat resistance and cold resistance by adoption of silicone grease.
• 2) It is excellent in load resistance due to containing of molybdenum disulfide.
• 3) It has reduced influence on plastic, resin, and rubber.
• 4) It is excellent in water resistance and oxidation stability and can thus be used as lubricant for a prolonged period of time.

Oils and greases are easily attached with dust, which may rather deteriorate their lubricity.
In such a case, a dry lubricating coating film is optimally formed on a metal surface.
To form the dry coating film, there is available a method including applying surface preparation treatment to the metal surface and spraying a resin-based lubricating coating material, followed by drying and fixing by baking.
However, considering the absence of such equipments and the easy handling, aerosol products are generally used.

Note: Baked dray lubricating coating film is advantageous over films formed using aerosol products in terms of strength and durability.

DKD-0801 MoS2 Paste Spray is used to form a semi-dry coating film of molybdenum disulfide on a metal surface. It is particularly excellent in terms of initial conformability and seizure-preventing ability.

DKD-0901 MoS2 Dry-coat Spray is used to form a dry coating film of molybdenum disulfide. It is optimally used for a portion vulnerable to oil and dust.

In general, a grease containing 3% Molybdenum disulfide can reduce friction by about 10%.
A molybdenum disulfide grease is produced by selection of a base grease, blending ratio of MoS2, and a combination of grain sizes so as to satisfy required load resistance, heat resistance, cold resistance, long service life.

For a molding die and an injector of an injection molding machine, cleaners and silicone sprays are suitably used respectively as a cleaning agent and a releasing agent for reduced coat and easy handling.

However, note the following:
1) When the molding die or injector of an injection molding machine has a high temperature, silicon residue may remain. This poses the inconvenience that much time and labor are required for removing this residue with an ordinary parts cleaner in addition to the above-mentioned problems involving use of the parts cleaner at a high temperature.

A fluorine grease spray is preferably used for lubrication of an injection molding machine.
As for the fluorine products, fluorine may be subjected to some restriction as one of environmental hazardous substances.
