The ability of the dry film layer to stay on the surface without blistering, flaking, or cracking. Adherence is perhaps paint’s most important quality. Wet adhesion, meaning the ability of the dry paint film to adhere to the surface despite wet conditions, is important mainly for exterior paints.
A synthetic polymer used in high-performance acrylic-based paint or water-based paints. Like the binder in paint, acrylic resins allow the coating to withstand chemicals and ensure the color lasts with their light-resistant properties.
These are resins characterized as having superb properties such as color and shine fastness, resistance to alkalis and oxidation, strong adherence and bonding, and film life and they occupy an elite position among coating formulas. These resins are usually formed as a result of polymerizing the derivatives of acrylic acids including acrylic acid, methacrylic acid, acrylonitrile, and the esters of their copolymers. They are also known as acrylate resins.
Acrylic Based Paint descriptions are listed below as alternatives:
Essentially, it is the fixed dispersion of a polymeric substance inside an aqueous medium.
Although they are used as binders in medium-grade equipment and marine enamels, they are the resins found in interior and exterior wood paints.
Essentially obtained by mixing lime and water. Used for interior decoration. Not resistant to washing.
Binds pigment fragments to form a uniform paint film and also ensures that the paint adheres to the surface. The type and amount of binder determine most of the paint’s performance characteristics, such as washability, hardness, adhesion, and color-retention. Resins such as acrylic polymers are the preferred binder in the production of quality, high-performance acrylic paints.
Loss of color due to exposure to sunlight.
The degree to which paint can withstand harmful environmental effects, particularly adverse weather. Durability has two main effects: Its protective qualities stop the surface from deteriorating. Its decorative qualities ensure that the impressive finish lasts.
The homogeneous dispersion of very thin solid particles in a liquid substance.
The ability of the paint to expand and contract without changing or damaging its finish. Changes in temperature cause expansion and contraction. For example, yellow pine expands at different rates depending on the particle size. Elasticity is the key to durability. Acrylic binders are renowned for their elasticity.
The process of dispersing one liquid chemical substance in another liquid chemical substance using an emulsifier.
When a very low viscosity liquid penetrates deep into a solid surface. This fills capillaries, gaps, and pores. It provides good adherence for the application that follows and increases the strength of the surface.
Topcoats characterized by the ability to form a smooth surface; they usually have a high gloss finish but can have a low gloss finish, such as matte enamels.
The ability of the paint to form a continuous dry film layer. This occurs when the water or solvent evaporates and the binding particles coalesce. The continuous dry film repels water.
It is cheaper than titanium dioxide and fills and expands the spaces of pigments. Extenders cannot be used without a pigment. Some commonly used paint extenders are kaolin, calcite, and silica.
The sum of the volume of pigment and binder divided by the total volume. Expressed as a percentage (%). High volume solids mean a thicker dry film layer, advanced coverage, and high durability.
The process of atomizing paint by pumping paint under very high pressure through a hole. It is the effect of the solvents evaporating, particularly when the paint is preheated.
The thinner and binder together form the paint’s medium of transmission. Water is the thinner used in acrylic paints; it evaporates as the paint dries and allows the paint to be applied smoothly. Turpentine or alcohol (methylated spirit) is used to thin oil paints.
Cavities or dome-shaped formations on the paint, usually caused by heat or moisture. They can also be formed by the solvent getting trapped in the paint film as its surface dries before the solvent has fully evaporated.
Its presence speeds up the chemical reaction. In some cases, the catalyst functions without being consumed or regenerated. In other cases, it looks as if it never reacted and functions with the authority of the surface characters. Negative catalysts (inhibitors) slow down the chemical reaction.
The paint’s resistance to flow. High-viscosity paints flow slowly, low-viscosity paints flow quickly.
Mildew is a problem frequently encountered in humid climates and its cause is chemical.
The ability of paint to cover or conceal the surface or previously applied paint and the stains on that surface. Coverage is provided by the paint’s pigment.
Uniformly round insoluble dispersed particles (powder) that can be natural or synthetic, inorganic or organic. In addition to coloring the paint, these particles also improve the basic properties of the paint such as opacity, stiffness, durability, and corrosion resistance by dispersing in the paint liquid. This term includes white or colored pigments as well as extenders. The difference between pigmented powders and dyes is usually determined by their solubility. During use, pigments are insoluble substances that disperse inside the medium, whereas dyes are soluble substances or exist in solution form.
The process of chemical compounds of different structures formed by the same or different monomers containing double bonds in the reactive structure with the help of heat, light, or catalysts. If a polymer chain consists of only one species of monomer, it is called HOMOPOLYMER; if it consists of two or more species of monomers, it is called COPOLYMER.
A colorless, thermoplastic, water-soluble, resinous high polymer derived from the polymerization of vinyl acetate and a catalyst. It is usually used as an acrylic-based paint binder in low-quality water-based coatings. Apart from this, adhesives are also used in textile and impregnation areas.
The ratio of the pigment volume to the total non-volatile substances (e.g., pigment and binder) in the coating. This ratio is usually expressed as a percentage (%).
The name given to most natural or synthetic transparent and soluble products. They can come in different colors. Synthetic resins have a high molecular weight and act as polymers.
They are solid, semi-solid, false (pseudo solids) solids that have an uncertain or very large molecular weight, gain fluidity when exposed to stress, have a softening and melting range, and break conchoidally.
This term is usually for any polymer that is the base material in coatings and plastics.
The ability of paint to maintain its original color and resist fading.
The lightening of a paint’s color due to exposure to heat or light.
When the paint comes away from the surface in strips or flakes. It occurs due to lost adherence similar to lifting off in layers.
When the paint comes away from the surface in pieces due to loss of adherence or elasticity.
The liquid portion of the pain in which the pigment is dispersed. It is a combination of binder and thinner.
The formation of a friable powder on the surface of the paint film caused by the disruptive effects of bad weather separating the binder medium. Chalking of the paint film can be affected by the choice and concentration of pigment. Choice of binding medium can also be a factor.
A bright white, high opacity pigment with no chalk used as the primary pigment in paints, plastics, and rubbers. It is obtained from mineral ore of the mineral ilmenite or natural titanium dioxide.
When the surface coating forms a crust on stone, bricks, plaster, or mortar usually due to the accumulation of while, soluble salts. Salt or free alkalis leaking from wet mortar or the neighboring concrete can cause this problem.
Carbon compounds that evaporate under standard test results. Essentially, all paint solvents except water are VOCs. The government may impose restrictions on the amount of VOC present in the paint to counter possible environmental and health impacts.
Any form of washing that will remove dirt from the surface of the paint film without harming it will make our job easier.
The ability of the coating to form a smooth paint film without leaving brush marks. High-quality acrylic paints have superb flow qualities.
