Kauri-butanol value Volume in ml at 25°C (77°F) of a solvent, corrected to a defined standard, required to produce a defined degree of turbidity when added to 20 g of a standard solution of kauri resin in normal butyl alcohol. For kauri-butanol values of 69 and above, the standard is toluene and has an assigned value of 105. For kauri-butanol values below 60, the standard is a blend of 75% n-heptane and 25% toluene and has an assigned value of 40. Abbreviation is KB value.

Lieberman-Storch method Procedure for the qualitative detection of rosin in vehicles. The rosin may be present as either free rosin (abietic acid), esterified rosin, or metal salts. In Europe, the Lieberman-Storch-Morawski test is more commonly used. Paint pigment, drying oils, polymers. 

Isomerized Oils n Oils which have been isomerized from a molecular rearrangement by several means, such as the catalytic action of alkalis, sulfur dioxide, nickel, etc. Isomerized oils exhibit greater reactivity, more rapid polymerization and greater drying rate than their non-isomerized parent oils.
