[vc_row][vc_column][vc_column_text]Solvents 646, 647 and 650<\/strong> are one of the most popular multicomponent solvents that are widely used for dissolving and diluting varnishes, paints and other paint and varnish materials in order to acquire the required consistency.<\/p>\n

In today’s article, we will talk about the difference between solvent 646 and 647, as well as how solvent 650 differs from others.<\/p>\n

What is the difference between solvents 646, 647 and 650?<\/h2>\n

Before determining the difference between these solvents, it is worth first considering each of these solvents separately.<\/p>\n

Solvent 646<\/strong> is a multicomponent solvent that is organic in nature and consists of toluene, ethanol, butyl acetate, butanol, ethyl cellulose and acetone. This solvent is used when working with nitro varnishes, nitro paints and nitro enamels, as well as with epoxy and acrylic paint and varnish materials. It is often used when working with putties to soften them.<\/p>\n

Solvent 647<\/strong> – the same as the previous one, this solvent is multicomponent and consists of toluene, butyl acetate, butanol and ethyl acetate. It is used for diluting and dissolving nitroenamels and nitrolacquers. It is often used in car workshops.<\/p>\n

Solvent 650<\/strong> is a multicomponent organic solvent consisting of ethyl cellosolve, butanol and xylene. It has a wide range of applications. It has a low water content (approximately 2%) and high coagulation (up to 60%), which is why it is valued among consumers.<\/p>\n

What is the difference between 646 and 647 solvent?<\/h3>\n

If we talk about the difference between solvents 646 and 647, the first thing to note is that the 647 solvent has a more gentle effect on the treated surface. It is because of this factor that it is often used in car workshops, where it is important not to damage the car body during painting.
\nAnother of the main differences between 646 and 647 solvents is their chemical composition.<\/strong> Although it is similar, as can be seen from the previously mentioned description of solvents, there is an important difference – solvent 647 does not contain acetone. This is what makes it possible to use it on surfaces that require careful and careful treatment.[\/vc_column_text][vc_column_text]The areas of use<\/strong> are also slightly different:<\/p>\n

    \n
  • 646 solvent<\/strong> should be used with caution, because it is highly active and is most often used for diluting nitrolacquers and nitroenamels. After drying, it leaves a shine on the surface after drying.<\/li>\n
  • 647 solvent<\/strong> is used for diluting paint and nitrocellulose materials, and is also widely used for smoothing strokes and irregularities on the surface.<\/li>\n<\/ul>\n

    In summary, we can say that the main difference between 646 and 647 solvent is the chemical composition, different effects on the treated surface and slightly different areas of application.<\/p>\n

    What is the difference between 650 and 646 solvent?<\/h3>\n

    The first difference is the chemical composition<\/strong>. Thus, solvent 646 consists of toluene (50%), ethanol, butyl acetate, butanol, ethyl cellulose and acetone, and solvent 650 contains xylene (50%), butanol and ethyl cellulose.<\/p>\n

    To determine which solvent is better to choose for your work, you need to understand for which materials the use of a particular solvent is appropriate.<\/p>\n

    Therefore, the next factor that differs significantly between these two solvents is the scope of application:<\/p>\n

      \n
    • Solvent 646<\/strong> – is used for diluting epoxy and glyphtal primers, varnishes and enamels, it is also used when working with nitro varnishes and nitro enamels. This solvent is used in the dissolution of organosilicon, epoxy, urea-formaldehyde and nitrate-cellulose film-forming materials.<\/li>\n
    • Solvent 650<\/strong> – most often used for diluting varnishes, primers, paints and enamels, perfectly dissolves nitrocellulose film formers. This solvent has a fairly wide range of uses and is used in relation to many types of paint and varnish materials.<\/li>\n<\/ul>\n

      Therefore, the difference between solvent 650 and 646 lies in the chemical composition and field of use.<\/p>\n

      What is the difference between solvent 647 and 650?<\/h3>\n

      Of course, the first thing by which you can determine the difference between 647 and 650 solvent is the chemical composition<\/strong>. Thus, solvent 647 is composed of toluene, butyl acetate, butanol, and ethyl acetate, as previously noted, and solvent 650 is composed of xylene (50%), butanol, and ethyl cellulose.<\/p>\n

      Both of these solvents are used in automotive painting, but the reason for their use is different:<\/p>\n
