AIR DRY:
To dry by air under ambient temperature.
ADHERENCE:
Adherence is the capacity of the dry film to stay on the surface without swelling, stripping or cracking. Adherence is probably the most important feature of a paint. It is important generally for the exterior paints to adhere while wet and also adherence of the dry film to the surface in wet environment.
ACRYLIC:
It is a synthetic polymer used in high performance acyrlic based paints or water based paints. Like the binder, acrylic resins let the paint to resist chemicals and permanency of the color against light.
ACRYLIC RESIN:
A type of resin which has a distinct place in coating formulas with color and gloss resistance, alkali and oxidation durability, hardness, adherence and binding strength and film longevity features accepted as superior. They are generally produced by polimerisation of acrylic acid, methacyrilic acid, acrylonitrile and acrylic acid derivatives which include the esters of the copolymers of those. They are also known as acrylat resins.
ARYLIC PAINT:
Acrylic based paint definition alternatives are submitted below for your kind information: (1) Mainly constant dispersion of polimeric substance in liquid (aqua) environment (2) Dispersion of plastic or resin in natural or synthetic water; made via synthetic, emulsion (mixture) polimerisation. (However, it should be noted that, after the polimerisation, the acrylic based paint is a solid dispersed in water, therefore it is not an emulsion. In paint industry, acrylic based paint and emulsion are used similarly. They are paints produced with synthetic binders like polyvinyl acetate or acrylic resins and thinned with water. Unlike solvent based paints, acrylic based paints dry fast, flow regularly and can be cleaned with water easily. High performance acrylic based paints contain 100% acrylic resin. They are thinned with water and most of the binder is made up of acrylic resin. Other binders included in the paint to add specific features or decrease costs are styrene, epoxy and polyvinyl acetate. %100 Acrylic based paint: They are thinned with water and acrylic binder is used as sole binder. Generally, high quality acrylic based paints are used for many diferent architectural coatings. 100%acrylic paints have super adherence, long term elasticity, permeability, alkali resistance, hardness and gloss resistance.
ALKYD:
Although they are used as binders in mid range equipment and marine enamels, they are resins used in
INTERIOR AND EXTERIOR WOOD PAINTS. SUBSTRATE:
Surface the coating is applied on.
PRIMER:
First coat applied during coating. It is used to let paint better adhere to the surface.
BINDER:
Binder binds the pigment parts in order to construct a smooth paint film and lets the paint adhere to the surface. The type and quantity of the binder determines most of the performance features –washability, hardness, adherence and color durability- of a paint. The binder used in quality, high peformance paints are resins like acrylic polymers.
BUBBLING:
Observance of bubbles on the surface whilst paint or coating dries. It is a consequence of excessive mixing or brushing of paint.
SOLVENT:
The liquid that can dissolve any resin. It is generally referred to the part of the paint which evaporates after application.
RESISTANCE:
It is the paint’s level of durability against corrosive environmental factors, especially to bad weather conditions. Resistance has two effects: Protective features protect the surface and decorative features provide the impressive outlook to be long-lasting.
BRIDGING:
The capacity of a paint to fill a crack or small hole.
DISPERSION:
Homogenous distribution of highly thin solid structured particles in a liquid subtance.
ELASTICITY:
The adequacy of a paint to expand or shrink without any change or harm to its appearance. Changes in temperature can lead to shrinkage and expansion. Therefore, yellow pine, depending on the particle size, expands in different ratios. Elasticity is the key of durability. Acrylic binders are well-known for their eleasticity.
IMPREGNATION:
The penetration of a very low viscosity liquid into and depth of a solid surface. Thus, capilary holes and pores can be filled. It provides a good adherence to the following coat/applicationand increases the resistance of the surface.
EMULSION:
A mixture of a liquid and the solid particles suspended in it. Emulsion paint: A type of paint in which resins are suspended in water e.g. latex paint.
EPOXY:
A very tough and durable synthetic resin used in some coatings.
FILM FORMATION:
The ability of a film to form continuous dry film sheet. This process forms by bonding of the binder parts whilst water or solvents evaporate. Continuous dry film repels water.
FILM THICKNESS:
Surface thickness of dry coating.
GALVANIZING:
Coating of thin zinc unto iron and steel to avoid rust. Permeability: The capacity of film sheet to let vapor to pass.
BRITTLENESS:
The tendency of a material to break when contorted. Relative humidity: A scientific method used to describe the humidity in air. It is denoted as percentage and describes the percentage of humidity at a given temperature.
POROSITY:
The permeability (water vapor/liquid) of paint film. Airless sprey: Atomization process of paint by high pressure from a hole with applied force. Especially when paint is pre-heated, it is the effect of paints moving further whilst solvents evaporate. Wet film thickness: The surface thickness of a coating when applied. Secondary colors: A color which is the mixture of any two primary colors e.g. green is the result of a mixture of yellow and blue.
COATING:
A general term used for paints, varnishes and lacquers.
CATALYST:
The substance which increases the speed of the chemical reaction when included.
COHESION:
The attraction force between same type of molecules. It is the force that keeps the molecules of a material together.
CURING:
The process where the wet paint dries and becomes a dry film sheet.
DRYING TIME:
The time needed for the applied paint or coating to reach the required hardness.
DRIERS:
The chemicals included to the coating to shorten drying time.
BLEEDING:
The unfavorable image when a pigment or paint underneath the top coat reaches to surface.
LATEX BASED PAINT:
It is water based emulsion paint produced with synthetic binders like %100 acrylic, vinyl acrylic and terpolymer. It is a balanced emulsion of polymers and pigments.
ANTI-CORROSIVE PAINT:
First coat applied unto steel, iron or other metal surfaces and prevents rust.
COAGULATION:
The accumulation of resin parts as a bigger rubber part in latex paints.
PIGMENT:
Very small and dissolving particles which provide the paint with color and covering features. Titanium dioxide is the most important pigment to provide covering feature to the paint.
POLYMER:
A material produced when its molecules repeat a certain structural order many times
ORANGE PEEL:
An orange peel like look on paint film.
COLOR RETENTION:
Self-protection feature of the paint. Sunlight, repeated cleaning activities and open air makes color protection harder.
HIDING POWER:
The capacity of the paint to cover the surface it is applied upon.
HARDNESS:
The durability of a surface against scratching and impact.
FADING:
The loss of paint color within time due to exposure to heat and light
WATER-BASED:
Coatings which have mainly water as liquid content.
CHALKING:
The dust on the paint sheet due to weakening of binders under natural conditions. Thermoplastic: The name given to materials which do not soften at all after being hardened by heating.
THINNER:
It is the volatile organic material used to fine-tune the viscosity of the paint.
AGGLOMERATION:
The gathering of pigments to form bigger parts.
EFFLORESCE:
Covering of coating with white crsytals or dust. It is seen a lot on brick walls.
RECEDING COLORS:
Colors which show equipment or surfaces like fading away e.g. blue and its shades.
VISCOSITY:
It is the resistance of a liquidity to flowing. Advancing colors: Colors which show equipment or surfaces like coming closer e.g. red, orange.
FIRE RETARDANT PAINT:
A type of paint which prevents flame spreads, durable against high temperatures and protects the surface applied.

The ability of a dry film to stay on the wall without cracking and swelling.
