Abrasion (resistance to):
|
 |
capacity of a film of paint to resist knocks and rubbing by particles and abrasive parts. |
|
|
Abrasive paper:
|
|
is the vehicle, usually paper of cloth, for the abrasive material used for sanding the support to be painted or for previous coats already applied. It has grains of varying size, defined by a number that shows the amount of mesh in a square inch (6,45 cm2) of the sieve, through which the abrasive grain passes corresponding to the same number. |
|
|
Abrasive:
|
|
due to its hardness and shape of the particles, a material used for engraving and eroding. |
|
|
Adhesion:
|
|
resistance paint opposes to the detachment action from the support or another layer of paint. |

|
Ambient humidity:
|
|
relative humidity in the painting environment, it should not be above 85%. |
|
|
Anchorage:
|
|
adherence capacity between the support and the base coat or between the base coat and other coats. |
|
|
Artificial ageing:
|
|
procedure that artificially and rapidly creates the ageing process that would be found in normal conditions of use. To test the life of the paint film on items used outside, sunlight and rain are reproduced using very sophisticated equipment, able to simulate in days/hours of testing the exposure conditions to weather over long periods of time. |
