Coating knowledge
1.
Under the specified drying conditions, the time required for a certain thickness of a wet paint film to change from a liquid to a solid surface but liquid below it
2.
Under the specified drying conditions, the time required from the application of a certain thickness of the liquid paint film to the formation of a solid paint film
3.
The ability of a substance to transmit light is online coatingol.
4.
The mass per unit volume of an object at a specified humidity
5.
The internal resistance of a liquid to flow
6.
The amount of non-volatile matter contained in the coating
.
Generally, it is expressed as a percentage of the mass of non-volatile matter, and it can also be expressed as a volume percentage
.
7.
Fineness of grind
A measure of the degree of dispersion of pigments and extender pigments in paints
.
That is, under the specified conditions, the reading obtained on the standard fineness meter, the reading indicates the depth of a groove in the fineness meter, generally expressed in micrometers (μm)
.
8.
Storage stability
Under the specified conditions, the coating product resists the odor, consistency, skinning, roughness, sinking, agglomeration and other performance changes that may occur after storage
.
9.
Compatibility
The ability of one product to be mixed with another product without causing adverse effects (such as precipitation, agglomeration, thickening, etc.
)
.
10.
Covering power
The ability of the color paint to eliminate the color or color difference on the substrate
.
11.
Construction application property
The difficulty of paint application
.
Note: The paint has a good workability, which generally means that the paint is easy to apply (brushing, spraying, dipping, etc.
), with good leveling, no sagging, wrinkling, shrinking, bleeding, or undercutting; moderate dryness, easy Good sanding and recoating properties, and low requirements for construction environmental conditions
.
12.
Recoatability
The difficulty and effect of multi-layer coating of the same paint
.
13.
Film thickness
A measure of the thickness of the paint film, generally expressed in micrometers (μm)
.
14 gloss
An optical property of a surface expressed by its ability to reflect light
.
15.
Adhesive force
The firmness of the bond between the paint film and the coated surface (through physical and chemical action)
.
The coated surface can be either a bare substrate or a painted substrate
.
16.
Hardness
The ability of the paint film to resist mechanical forces such as collisions, depressions, and scratches
.
17, flexibility
The ability of the paint film to be shaped together with its substrate without being damaged
.
18 abrasive resistance
The resistance of the paint film to friction
.
19.
Rubbing property
The paint film or putty layer is polished (dry or wet) with pumice, sandpaper and other materials to produce a smooth and matte surface
.
20, yellowing
The tendency of the paint film to turn yellow during the aging process
.
21.
Temperature change resistance
The ability of the paint film to maintain its original performance after being subjected to alternating temperature changes with cold and heat
.
22.
Clouding
Varnishes or thinners appear cloudy and opaque due to the precipitation of insoluble matter
.
23.
Thickening
Coatings usually increase in consistency due to the loss of thinner during storage
.
24, flocculation
The phenomenon of forming agglomerates in paints or dispersions
.
25, gelling livering
A phenomenon in which paint changes from a liquid state to an unusable solid or semi-solid state
.
26, skinning
A phenomenon in which paint forms a film on the liquid surface due to oxidative polymerization in the container
.
27, precipitation sediment
The phenomenon that the solid components of the paint sink to the bottom of the container in the container
.
28, caking
Particles such as pigments and extender pigments in the paint settle into dense masses that are not easy to redisperse with stirring
.
29, there are coarse seedy
Coarse particles (that is, a little crust, gel, agglomerates or foreign coarse particles) exhibited by the coating during storage
.
30, return rough pig shin
The phenomenon that the fineness of the grind becomes worse due to the flocculation of the pigment during the storage of the colored paint
.
31.
Floating
During the storage or drying process of colored paints containing a variety of different pigment mixtures, one or more of the produced materials segregate or float and concentrate on the surface of the colored paint or paint film to show uneven color streaks and spots
.
32 Flooding
The extreme condition of blooming
.
33.
Bubble bubbling
The air or solvent vapor and other bubbles formed during the coating process, or both bubbles, can disappear during the drying process of the paint film, and they can exist permanently
.

A phenomenon in which the gloss of the paint film is reduced due to the influence of the climate environment
.
