Water-borne Preservatives

Traditionally, water borne preservatives are most commonly used in the industry due to their availability and low cost. Some water-borne preservatives include:

Oil Borne

Oil borne preservatives such as creosote and pigment emulsified creosote are a complex mixture of chemicals obtained from the distillation of coal tar. Being a liquid it is normally used without the addition of a solvent. Fuel oil is, however, is sometimes added to facilitate the treatment of railway sleepers.
