An iron containing metal. |
| Filler |
A compound used to extend or bulk a coating to provide
extra body or hiding power. |
| Film |
A layer of coating or paint. |
| Film Build |
The dry film thickness characteristics of a coat. |

Any substance easily ignited in the presence of a flame;
any liquid having a flash point below 100° F (37.8° C). |
| Flash Point |
The lowest temperature of a liquid at which sufficient
vapor is provided to form an ignitable mixture when mixed with air. |
| Flash-Off-Time |
Time which must be allowed after the application of a
paint film before baking in order that the initial solvents are released, which prevents
bubbling. |
| Flexibility |
The degree at which a coating is able to conform to
movement or deformation of its supporting surface without cracking or flaking. |
| Floating (Flooding) |
A concentration of one of the ingredients of the pigmented
portion of a paint at its surface giving rise to a color change. |
| Flow |
The degree to which a wet paint film can level out after
application so as to eliminate brush marks and produce a smooth uniform finish. |
| Fluid Tip |
The orifice in a spray gun to which the needle is seated. |
| Fluorescent |
A class of pigments which, when exposed to visible light,
emit light of a different wave length producing a bright appearance. |
| Force Drying |
The acceleration of drying by increasing the ambient
temperature. |
| Foreign Thinner |
Any thinner not recommended on the label or in published
literature of the manufacturer, which can affect the coatings performance. |

The ability to retain the original sheen during
weathering. |
| Glycol Ether |
A group of relatively slow evaporating, strong solvents
commonly utilized in epoxy coatings. |
| GRIDGARD® |
GRIDGARD is a trade name used by the Carboline Company to
describe a group of coatings made for the Power Industry. |
