Intermediate Coat:-
Any film of coating material that lies between the primary and finishing coats of a coating system.

Intumescent Coating:-
A coating material which by foaming or swelling forms a voluminous substance when exposed to heat

Krebs Stormer:-
Rotational viscometer which is relatively simple to use and reads viscosities for thixotropic liquids in the "brushing" range. The apparatus basically measures the force required to rotate a paddle at a speed of 200 rpm in the test liquid. The viscosity is expressed in Krebs units

Lacquer:-
A coating based on a non convertible binder which dries purely by solvent evaporation

Lacquer dry:-
The initial drying phase of a system (often a blend of convertible and non-convertible binders). The system dries to tack free like a lacquer but needs time to fully convert. Examples - styrenated alkyd, n/c alkyd blends.

Latex:-
A dispersion of a solid in a liquid. Often used as a synonym for a dispersion binder. a dispersion of a polymer in an essentially aqueous medium. See emulsion.

Lifting:-
Rising of dry film on application of second coat or on submersion in a liquid. Effect caused by paint removers. Film detaches and crumples. Coating with non-recommended top coat. Incorrect thinners attacking convertible coating. See wrinkling .

Mar Resistance:-
The ability of a coating to resist damage caused by light abrasion, impact or pressure.

Mineral turpentine:-
See white spirits

Mineral spirits:-
see white spirits

Mottling:-
Uneven effect in metallic finishes. Caused by heavy wet coats. Build-up of electrostatic charges. Poor mixing of paint. Conditions too cold.
