| Bituminous Coating |
A coal tar or asphalt based coating material
usually used in thick films. |
| Blast Cleaning |
The cleaning and roughing of a surface by the
use of sand, artificial grit or fine metal shot which is projected at a surface by
compressed air or mechanical means. See SSPC. |
| Blast Profile |
See anchor pattern. A cross sectional view of
an abrasive blasted surface. |
| Bleaching |
The fading of a color toward white generally
caused by exposure to chemicals or ultraviolet radiation. |
| Bleeding |
The diffusion of color matter through a
coating from underlying surfaces causing color change. |
| Blistering |
The formation of blisters in paint films by
the local loss of adhesion and lifting of the film from the underlying substrate. |
| Blooming |
A haziness which develops on paint surfaces
caused by the exudation of a component of the paint film. |
| Blushing |
A film defect which manifests itself as a
milky appearance which is generally caused by rapid solvent evaporation or the presence of
excessive moisture during the curing process. |
| Bonding |
The attachment between a coating film and the
underling material to which it is applied. |
| Bounce Back |
The rebound of atomized paint, especially when
applied by conventional air spray methods. |
| Boxing |
Mixing of coatings by pouring from one
container to another. |
| Bridging |
The formation of a paint film over a
depression. |
| Brittleness |
The lack of resistance to cracking or breaking
of a paint film when bent or flexed. |
| Brushability |
The ease of applying a coating by brush. |
| Bubbling |
A temporary or permanent film defect in which
bubbles of air or solvent vapor are present in the applied film. |
| Build |
The wet or dry thickness of a coating film. |
| Carbo Zinc |
Trade name for a group of Carboline zinc
filled coatings. The Carboline Company is the world leader in developing, producing and
selling inorganic zincs and has, over the last 40 years, protected over 2 billion square
feet of steel with our Carbo Zinc 11. |
| Carboline® |
Manufacturer of high performance Industrial
coatings.350 Hanley Industrial Court, St. Louis, MO 63144-1599 - 314/644-1000 |
| CARBOMASTIC® |
CARBOMASTIC has become known to mean
"High performance, in hard to clean areas". Carboline's Carbomastic 15 was the
original Aluminum Epoxy Mastic. This grouping of products includes the two component
surface tolerant epoxies. They are normally used in situations where abrasive blasting in
not an option. However, like any good quality epoxy, you will increase the service life of
the system as you increase the cleaning level! Carbomastics can be topcoated with most any
generic type top coat and will go over just about any aged coating. They can also be used
as standalone one or two coat systems. |
| Catalyst |
An accelerator, activator or curing agent
which chemically increases the rate of reaction in a coating. |
| Cathode |
The negative terminal of an electrolytic cell
which, in the corrosion process, is protected and not attacked. |
| Cathodic Protection |
The reduction or prevention of corrosion of a
metal surface caused by making it cathodic. This is accomplished by using a sacrificial
anode (such as in zinc rich coatings or galvanizing) or by using impressed current. |
| Caustic |
A strong base or alkaline material. |
| Caustic Soda |
A common name for sodium hydroxide, a strong
base or alkali. |
| Cellosolve |
Proprietary name for ethylene glycol monoethyl
ether. A slow evaporating, water miscible, relatively strong solvent often used in epoxy
coatings. |
| Cementitious Coatings |
A coating containing Portland cement as one of
its components held on the surface by a binder. |
| Centipoise |
One hundredth of a poise which is a unit of
measurement for viscosity. Water at room temperature has a viscosity of 1.0 Centipoise. |
| Chalking |
The formation of a friable powdery coating on
the surface of a paint film, generally caused by exposure to ultraviolet radiation
resulting in a loss of gloss. |
| Checking |
Cracks in the surface of a paint film. |
| Chipping |
Small pieces of paint removed from the
surface, typically a sign of physical damage incurred in shipping or handling. Use of a
surface tolerant primer for touch up followed by the same finish coat generally solves the
problem. |
| Chlorinated Hydrocarbon |
A class of strong, fast evaporating,
nonflammable solvents such as carbon tetrachloride, methylene chloride or
trichloroethylene. |
| Chlorinated Rubber |
A coating resin formed by the reaction of
rubber with chlorine gas. Often used for chemical or water resistant properties. |
| Clean and Dry |
Rather than a method, the requirement for
Clean and Dry describes the condition of the surface prior to painting.The surface shall
be clean, dry, and free of oil, grease, wax, form oils, and any other contaminant that may
effect the adhesion of the coating. For best results and high performance requirements
remove laitence and contaminants from precast and cast-in-place concrete by abrasive
blasting or high pressure water blasting.Dry means that the substrate contains less then
15% moisture.Concrete should be cured at least 28 days and mortar joints at least 15 days
@ 75°F and 50% RH.See also: ASTM D 4263 - 83; ASTM D 4258 - 83; ASTM D 4259 - 83; ASTM D
4260 - 83; ASTM D 4261 - 83; ASTM D 4662 - 83 |
