Paints contain extenders, solvents, pigments, binders, and some additives. The objective is to improve some physical properties of the current matt paint formulation. The contents of acrylic white matt emulsion paint are known to be 25%Pigments, 12% Extender pigments, 5% Additives, 44% Solvents, and 14% Binders. [2]. Binders are matrices and are used to hold the pigment in place. Extenders have larger pigment particles to improve adhesion and to strengthen the film and save the binder. Pigments are used to give color and opacity to the paint. Solvent can be either organic solvent or water and is used a thinner and to dissolve paint components and make it uniform. Additives are commonly used to improve properties of the paint.

Abstract
Paints are used to protect and prolong the life of natural and synthetic materials as it acts as a barrier against
environmental conditions. Paints contain extenders, solvents, pigments, binders, and some additives. The objective is
to improve some physical properties of the current matt paint formulation. The contents of acrylic white matt emulsion
paint are known to be 25% Pigments, 12% Extender pigments, 5% Additives, 44% Solvents, and 14% Binders. [2].
Binders are matrices and are used to hold the pigment in place. Extenders have larger pigment particles to improve
adhesion and to strengthen the film and save the binder. Pigments are used to give color and opacity to the paint.
Solvent can be either organic solvent or water and is used a thinner and to dissolve paint components and make it
uniform. Additives are commonly used to improve properties of the paint.

Introduction
The company is looking to improve the properties of the current acrylic
matt paint formulation as the current formulation shows a low scrub
resistance test compared to the reference. The current paint scrub-
resistance test shows the paint operates 60% effectiveness compared to
the reference.
The current formulation consisted of 47% Vinyl acetate, 0.1258%
Potassium Persulfate, 0.0234% Tertiary butyl hydrogen peroxide, 0.06%
Hydrogen peroxide, 0.05% Sodium formaldehyde sulfoxylate, 1.0% Di
butyl phthalate, 0.1% Formaline, 0.05% biocide, 0.1% Silquest A-171 and
0.06% defoamer , 0.4% Natrosol 250- HHBR, 44.39% water,0.14%
Sodium Bicarbonate, 2.0% Polyoxyethylene 25 octyl phenol, 2.0% Octyl
phenol polyglycol ether sulfate sodium salt, 0.5%, Provichem, and 2.0%
Buyl acrylate, [1]. The objective is to find chemical compounds that
would potentially lower the scrub resistance and find additives and
chemical compounds that would potentially increase the quality and
increase the scrub resistance test for the acrylic matt paint. Chemical
names, molecular formulas and molecular weights of all chemical
compounds used in making the current acrylic paint formulation are listed
in table 1.[3]
An acrylic white matt emulsion paint is known to consist of 25%
Pigments, 44% Solvents, 12% Extender pigments, 5% Additives, and
14% Binders, Figure 1 [2]

Table 1: Chemical name, molecular formula, chemical formula and the role of chemical compounds used in the current acrylic paint formulation.
Detailed Analysis
The current acrylic paint formulation consisted of mainly of 44.39% water
as solvent, 49% pre-emulsion monomers (vinyl acetate and butyl acrylate)
and 6.61% additives (Natrosol 250-HHBR, Sodium Bicarbonate,
Polyoxyethylene 25 octyl phenol, Octyl phenol polyglycol ether sulfate
sodium salt, Provichem, 2.0% Buyl acrylate, Potassium Persulfate,
Tertiary butyl hydrogen peroxide, Hydrogen peroxide, Sodium
formaldehyde sulfoxylate, Di butyl phthalate, Formaline, biocide,
Silquest A-171 and defoamer).
Conclusion
The current formulation consists of pigments 0.14% in the form of
Sodium Bicarbonate, compared to literature amount 25%, extender
pigments weren’t used in the current formulation compared to literature
amount 12%, surfactants 4.5% compared to literature amount 0-1%, and
binders 49% compared to literature amount 14%. The current paint scrub-
resistance test shows the paint operates 60% effectiveness compared to
reference due to missing 40% of main ingredients that makes a good
acrylic paint. It has been found that main chemical compounds are
missing from the current formulation: pigments, extenders, and another
type of pre-emulsion monomer. It also has been found that copious
amounts surfactants 4.5% (2.0% Octyl phenol polyglycol ether sulfate
sodium salt, 2.0% Octyl phenol Polyglycol Ether Sulphate Sodium Salt,
and 0.5% Provichem) have been causing a low scrub resistance test of
current formulation compared to reference. It’s recommended to avoid
using copious amounts of surfactants and it’s also recommended to use
pigments and extenders in order to form a firm protective layer and
prevent the dissolution of paint film from the surface and to improve the
scrub resistance test of the acrylic paint.

Paints are used to prolong the life of natural and synthetic materials and to protect it, it acts as a barrier against environmental conditions. Mainly paints are made up of solvent, biner, extenders, pigments(s), and some additives. Solvent can be either organic or Inorganic, and it's used as medium to dissolve paints contents together and make it uniform, it can also be used as a thinner. Pigments are used to give color to the paint. Binders are used to hold pigments in place. Extenders have large pigment particles to improve adhesion properties of the paint, and they are also used to strengthen the film and save the binder. The objective is to find the chemical compounds and the literature amounts that makes a good acrylic paint, find chemicals that would potentially lower the scrub resistance, and find additives and chemical compounds that would potentially increase the quality and increase the scrub resistance test for acrylic paints. After researching the chemical properties and role of each chemical compound used in the current formulation and comparing the amounts used to reference values, it has been found that main chemical compounds are missing from the current formulation: pigments, extenders, and another type of pre-emulsion monomer. It also has been found that copious amounts surfactants 4.5% (2.0% Octyl phenol polyglycol ether sulfate sodium salt, 2.0% Octyl phenol Polyglycol Ether Sulphate Sodium Salt, and 0.5% Provichem) have been causing a low scrub resistance test of current formulation compared to reference.

A preliminary study of the composition of commercial oil, acrylic and vinyl paints and their behaviour after accelerated ageing conditions
Article
Full-text available
  • Dec 2014
his study is part of a research project dealing with the establishment of monitoring and damage prevention plans for contemporary artworks. For this purpose, some commercial paints, among the most currently used by young artists, were selected: Winton oil paint (Winsor & Newton, UK), Heavy Body acrylic paint (Liquitex, USA) and Flashe vinyl paint (Lefranc & Bourgeois, France). The paints were subjected to different treatments of accelerated ageing, the results indicating different behaviour in relation both to the type of binders and pigments present in the different formulations. In particular, it was observed that ageing produced by ozone plays an important role in the stability of the oil paints, above all in those containing organic azo pigments. Thermal ageing, as expected, influences the stability of all the commercial paints examined, with the formation of alteration products and visible changes in the paint films. Ageing produced by moisture clearly affects the synthetic polymer-based paints, particularly evident in the changes in mass. In all cases, the accelerated ageing treatments produced chromatic variations, more evidently for the oil paints containing organic pigment.

The kinetic study of the polymerization of methyl methacrylate initiated by hydrogen peroxide in toluene, ethyl acetate, and methyl ethyl ketone as well as in bulk has been made. It has been established that the catalyst has no inhibition period and follows the square root relation. The initiation order is unimolecular with respect to the monomer in the fist two solvents and is half-molecular with respect t o methyl ethyl ketone. The value of Δ (= κ/κp) for methyl methacrylate a t 60°C. a t various concentrations in the three solvents has been measured and found to remain sensibly constant and its value is 8.43. From bulk polymerization data the value of Δ at temperatures of 50, 60, 80, and 115°C. has been determined and they are 11.62, 8.43, 5.26, and 2.48, respectively. The temperature variation of Δ, and hence the corresponding energy of activation (Ep − 1/2Et), has also been measured and its value is found to be 5.71 kcals. The initiation constant under a variety of conditions has been determined by two independent methods (kinetic and DP) which have been found to yield values in fairly good agreement with each other, leading to a strong support to the usually assumed mechanism of polymerization. However, the initiation constant is found to change considerably with monomer concentration and change of solvent.
