PAINT SECTOR TERMS

Adherence: It is the ability of the dry film layer to stand on the surface without blistering, getting up in thin layers or cracking. Adherence is perhaps the single most important feature of paint. Wet adhesion, the ability of the dry paint film to adhere to the surface, despite wet conditions, is generally important for exterior paints.

Acrylic: It is a synthetic polymer used in high performance acrylic based paint or water based paints. Like the binder of the paint, acrylic resins allow the coating to withstand chemicals and remain permanent due to light sensitivity.

Acrylic Resin: Resins, which are characterized as superb features such as color and gloss resistance, alkali and oxidation resistance, hardness, adhesion and bond strength and film life, and have a distinguished place among coating formulas. Generally, they are resins formed by polymerization of acrylic acid derivatives containing acrylic acid, methacrylic acid, acrylonitrile and esters of their copolymers. They are also known as acrylate resins.

Acrylic Based Paint: Acrylic Based Paint recipes are presented for your information as alternatives below:

(1) Constant dispersion of polymeric substance, mainly in aqua environment. (2) Dispersion of plastic or resin in natural or synthetic water; It is made by synthetic, emulsion polymerization. (It should be noted that after polymerization, acrylic-based paint is a solid dispersed in water, so it is not emulsion. Acrylic-based paint and emulsion are used in paint industry.)

They are water-thinned paints made with synthetic binders such as polyvinyl acetate or acrylic resins. Unlike oil paints, acrylic-based paints dry quickly, run smoothly and can be easily cleaned with water. High performance acrylic based paints contain 100% acrylic resin.

Most of its binders are paints that are thinned with water, which forms acrylic resin. Other binders added to the dye to add specific properties or reduce costs are styrene, epoxy and polyvinyl acetate.

100% Acrylic Based Paint: These are paints that are thinned with water, which is used only with acrylic resin as binder. Generally, high quality acrylic based paints are used for many different architectural coatings, they have 100% acrylic based paints, super adherence, long-term flexibility, breathability, alkali resistance, hardness and gloss resistance.

Alkyds: Although they are used as binders in medium grade equipment and marine enamels, they are resins in wood paints inside and outside.

Whitewash: It is mainly obtained by mixing lime with water. It is used for interior wall decoration. It is not resistant to washing.

Binder: It binds the pigment parts to form a uniform paint film and also allows the paint to adhere to the surface. The type and amount of binder determines most of the paint's performance properties (washability, hardness, adhesion and color strength). The binders preferred in the production of high quality acrylic based paints are resins such as acrylic polymers.

Whitening: Color loss caused by exposure to sunlight.

Durability: It is the degree of resistance of the paint to the harsh environmental effects (especially bad weather). Durability has two effects. Its protective properties protect the surface from deterioration. Its decorative features make its impressive appearance permanent.

Dispersion: It is the process of homogeneously dispersing very fine solid particles in a liquid substance.

Elasticity: It is the ability of the paint to expand and contract without changing or damaging its appearance. Temperature changes cause expansion and contraction. For example, yellow pine expands at different rates depending on the particle size. Elasticity is the key to endurance. Acrylic binders attract attention with their elasticity.

Emulsion: The process of dispersing the liquid substance in another liquid chemical with the help of an emulsifier.

Impregnation: It is the penetration and penetration of a very low viscosity liquid into a solid surface. In this way, capillary spaces and pores can be filled. It creates good adherence to the application that can come after itself and increases the strength of the surface.

Enamel: Usually high brightness but also low brightness degrees; matte enamels, for example, are topcoat paint characterized by the ability to form a smooth surface.

Film Formation: Ability of paint to form a continuous dry film layer. This process results from the evaporation of water or solvents and the joining of the binder parts. Continuous dry film repels water.

Expander: It is cheaper content than titanium dioxide that fills and expands the voids of pigments. The extender can not be used without pigment. Some commonly used expanders are; kaolin, calcite and silica.

Volume solids: Total of the volume of pigment and binder divided by total volume. It is expressed as a percentage (%). Higher volume solids mean thicker dry film layer, enhanced hiding power and high durability.

Airless spraying (spraying): The atomization process of paint by applying force through a hole with high pressure. Especially when the paint is preheated, it is the effect of the solvents starting by evaporation.

Thinner: The thinner and binder together form the transport vehicle of the paint. Water is thinners used in acrylic-based paints, evaporating as the paint dries, allowing smooth paint application. Thinners of oil paints are turpentine or alcohol (spirits).

Blistering: Usually caused by heat or moisture, cavities on the paint, dome-shaped formulations. It may also occur as a result of the imprisonment of the solvent in the paint film, which dries before the solvent completely flies.

Catalyst: Its presence increases the speed of the chemical reaction. In some cases, the catalyst functions without being absorbed and regenerated. In other cases, it appears to have never reacted and functions under the authority of surface characters. A negative catalyst (inhibitor) slows down the chemical reaction.

Consistency (Viscosity): Flow resistance of paint. High viscosity paint flows slowly; less viscous paint flows quickly.

Mold: It is a chemical causing mold, which is a common problem in humid climates.

Covering: Ability of paint to cover or cover the surface or previously applied paint and stains on the surface. Covering is provided with the pigment of the paint.

Pigment: Smooth round, natural or synthetic, inorganic or organic, insoluble dispersed parts (powder). These parts, by dispersing in the paint liquid, not only color the paint, but also improve the basic properties of the paint, such as opacity, stiffness, durability and corrosion resistance. This term included in expanders with white or colored pigments. The difference between pigmented powders and dyes is generally examined on the basis of solubility. During use, pigments are materials that are insoluble and dispersed in the substance, and paints are soluble or in solution.

Polymerization: It is the process of chemical compounds of different structures formed by the same or different monomers containing reactive double bonds with the help of heat, light or catalysts. If a polymer structure consists of only one type of monomer, it is called HOMOPOLYMER, and if it consists of two or three different types of monomers, it is called COPOLYMER.

PVA (Polyvinyl Acetate): It is a colorless, thermoplastic, water-soluble, resinous high polymer that is derived from the polymerization of vinyl acetate and a catalyst. It is generally used as an acrylic-based paint binder in low-quality water-based coatings. In addition, it is a resin used in adhesives, textile and impregnation areas.

PVC (Pigment Volume Concentration): It is the ratio of pigment volume to total non-volatile substances (eg pigment and binder) in the coating. This rate is usually expressed as a percentage (%).

Resin:

(1) The name given to a large part of natural or synthetic transparent and melting products. They can be found in different colors. Synthetic resins with high molecular weight act as polymers.

(2) Solid, semi-solid, pseudomerical solids with uncertain or very large molecular weight, fluidity when exposed to stress, softening and melting intervals, and concoidal breaks.

(3) Generally, this term is used in place of any polymer that is the basic material in coatings and plastics.

Color Resistance: It is the ability of the paint to protect its original color and resist fading. Fading: The color of the paint exposed to light or temperature.

Peeling: Removal of the paint from the surface in strips or leaves. It occurs as a result of loss of adherence, similar to getting up in layers.

Getting up in layers: As a result of adherence or loss of elasticity, the paint is separated from the surface in pieces.

Carrier: The liquid part of the paint in which the pigment is dispersed. It consists of a combination of binder and thinner.

Chalking: Easily friable dust formation on the paint film surface caused by weathering effects by separating the binding medium. The chalk of the dye film can be affected by the choice and concentration of the pigment. The choice of binder media can also be effective.

Titanium dioxide (TiO2): It is a high opacity, chalk-free light white pigment used as primary pigment in paints, plastics and rubbers. It is obtained from mineral ilmenite or natural titanium oxide mineral ore.

Pollination (blooming): The accumulation of surface coatings by accumulating white, soluble salts on stone, brick, plaster or mortar. Salt or free alkalis leaking from moisture through the grout or adjacent cement cause this problem.

VOC (Volatile Organic Content): Carbon compounds that evaporate under standard test results. Essentially, all paint solvents, except water, are UOC. The government can determine to limit the amount of volatile organics present in the dye against potential environmental and health effects.

Spread: The ability of the coating to form a uniform paint film without any brush marks. High quality acrylic based paints have super spreading ability.

Washability: Washing method, which will allow dirt to be removed from the surface of the dry paint film without damage, makes our work easier.
