WD-40 formula. now they could have added some form of silicone during their 40 years of existence but common chemical sense tells me they did not, or didn't need to.
70% low aromatic white spirits ( stoddard solvent ) simular to Kero but not kero.
~20% lubricant base grade ( solvent de-waxed, paraffinic type )
10% of corrosion inhibitor ( some formulations use 2 inhibitors, normally they would only be present at low concentrations, so it's possible that the inhibitor could be something crude like an oil that produces a hard film with synthetic additives ) Parafins most likely
5% of wetting agent ( probably quite low concentration, other the formulation would emulsify some water which could affect theprotective film's durability and performance )
<5% of fragrance.
A street bike chain with or without sticky lube, any kind of lube, will gather fine particles of sand, salt, minerals, glass and metals from the road. So it's best to clean it and your sprockets. roller links and pin links should be cleaned of that grit paste. this grit is the stuff that can wear, cut and loosen o-rings.
