• Percent Volatile (maximum): 70% by weight aliphatic petroleum distillate
• Pour Point: Below -73°C
• Coverage: 14m2 to 24m2 per litre
• Boiling Point (Initial): 149°C (minimum)

Under actual conditions the duration obtained using WD-40 will vary with the type of material being protected and the conditions of exposure. Generally, on mild steel the protection under various will be approximately as follows:

• Covered or indoor storage 1 year or longer
• Protected exterior storage 6 months to 1 year
• Normal exterior exposure 30 to 60 days
• Severe exterior exposure 15 to 30 days (on or very near the beach, subject to high humidity, salt spray and salt fog). If longer protection is desired, WD-40 should be lightly reapplied when necessary.

0.0066 0.0083 ohm 0.0067 0.0085 ohm 0.0069 0.0086 ohm 0.0074 0.0085 ohm 0.0083 0.0098 ohm

CONTACT RESISTANCE OF FILM

Nearly all materials react to WD-40 as they would to high grade aliphatic petroleum spirits with the same exposure, i.e., spray, quick dip or prolonged immersion. WD-40 contains no silicone, PTFE or chlorofluoracarbons.

RUBBER:

No visible effects on surface of various types of rubber sprayed with WD-40. Certain types of rubber will swell upon prolonged immersion in WD-40.

HIGH STRENGTH STEELS: (for hydrogen embrittlement) Certified SAFE according to the Lawrence Hydrogen Effusion Test.

FABRICS:

The following fabrics were exposed to WD-40 with no effect, expect slight staining which was readily removed with naphtha or dry cleaning solvent: Nylon, Orlon, Wool, Dacron, Cotton.

PAINTED SURFACES:

Many types of paint on various surfaces have been exposed to WD-40 with no effect. Wax polishes and certain wax coatings may be softened by WD-40.

PLASTICS:

The following plastics were immersed in WD-40 for 168 hours with no visible effects:

• Polyethylene
• Delrin
• VinylTeflon

Clear polycarbonate and polystyrene may stress craze or crack in contact with WD-40.

APPLICATION

• Spray
• Brush
• Dip

NOTE: Application of permanent coatings over WD-40: Best results will be obtained when the surface is cleaned. Mineral spirits, lacquer thinner, vapour degreasing or alkaline cleaner are suitable.
