components of paints and coatings The following glossary contains terms used commonly in the paint and coatings industry to describe the characteristics, usage and components of paints and coatings.


Results for "I"
Illuminance
The density of light on a surface when it is uniformly illuminated.

Immersion
Referring to an environment which is continuously submerged in a liquid, often water.

Impact resistance
Ability of a coating to resist a sudden blow. Ability to resist deformation from impact.

Impact test
Used to assess the adhesion and flexibility of applied coatings. A weighted plunger is allowed to fall from a specified height onto the front (direct) or back (reverse) of a coated panel. The extent of the damage caused by the impact is used as a basis for assessing the adhesion and flexibility.

Impact-reducing materials
Wood mulch, wood chips, sand or pea gravel used to soften the landing of a child falling or jumping from any part of a play structure.

Incompatible
This term indicates that one material cannot be mixed with another specified material without separation or impairment of properties.

Indirect lighting
A more subdued type of lighting that is not head-on, but rather reflected against another surface such as a ceiling.

Induction Time
The period of time required after the mixing of two component products prior to use (same as Sweat-In Time).

Inert
Chemically inactive; resistant to corrosion. 
Inert base
A paint base which does not provide hiding, color or drying properties. Its main function is to provide solids, usually at low cost.

Inhibitive Pigment
A pigment which assists in the prevention of the corrosion process.

Inhibitor
Any substance which slows or prevents chemical reaction or corrosion.

Ink flaking
A problem that occurs when the color element of the design begins to come off the decorative surface of wallpaper. Causes include defects in the manufacturing process, adhesive on the decorative surface and the use of abrasive detergents.

Inlay
A decoration, usually consisting of stained wood, metal or mother-of-pearl, that is set into the surface of an object in a pattern and finished flush.

Inorganic
Matter other than that of animal or vegetable origin. For example, minerals and simple salts are inorganic materials.

Inorganic Zinc
A coating based on a silicate resin and pigmented with metallic zinc which has excellent resistance to organic solvents and general weathering.

Inside corner molding
A molding with a concave or convex shape facing the center of a room and flat surfaces on the other sides that attach to the walls, usually at 90-degree angles. Use this type of molding on corners when there is a void space or when the corner is exceptionally out of square. Inside corner molding also helps hide a mismatch of wallpaper in a crooked corner.

Inside corners
A corner formed when two walls join facing each other, usually at a 90-degree angle.

Insoluble
The inability to be dissolved. 

Intensity
The brightness or dullness of a color. Also referred to as a color's purity or saturation.

Intercoat
A layer of paint that is “sandwiched” between two others. Also refers to something occurring between coats, as in “inter-coat adhesion.” 

Intercoat Adhesion
The bonding power between successive coats of paint.

Intercoat Contamination
The presence of foreign matter such as dust or dirt between successive coats of paint.

Interlocked grain
Wood in which the fibers incline in one direction in a number of rings of annual growth, then gradually reverse and incline in an opposite direction in succeeding rings, and then reverse again.

Intermediate Coat
The coating between the primer and topcoat.

Intermediate colors
Colors made by mixing equal amounts of one primary and one secondary color, such as red-orange and blue-green.

Intermediate layer
The middle layer in some types of wallpapers, found between the decorative surface and the substrate. The intermediate layer provides extra opacity, especially if it contains a color other than white or off-white.

Intermix
To thoroughly combine two or more containers to achieve uniformity.

Internal Mix
A spray gun in which the fluid and air are combined before leaving the gun.

International style
A post-World War II architectural and decorative style that emphasized simplicity and lacked ornamentation. Smooth surfaces, an extensive use of windows, and white walls are hallmarks of this pared-down style.

Intumescence
A mechanism whereby fire-retardant paints protect the substrates to which they are applied. An intumescent paint puffs up when exposed to high temperatures, forming an insulating, protective layer over the substrate.

In-place Management
A series of steps used as an alternative to lead-based paint removal. Improves condition of intact lead-based paint to reduce and/or eliminate hazards without total removal.

Ion
An atom or group of atoms possessing a positive or negative electric charge as a result of having lost or gained an electron.

Iron Oxide
The naturally occurring state of steel; rust.

Island
A base cabinet and countertop unit that stands free, not touching any walls, so there is access from all four sides.

Isocyanate resins
Resins synthesized from isocyanates and alcohols. The reactants are joined through the formation of the urethane linkage and hence this field of technology is generally known as urethane chemistry.

Isopropyl Alcohol
A volatile, flammable liquid used as a solvent commonly known as rubbing alcohol.
