What is the difference between acrylic alkyd and modified alkyd?

∙ 15y ago
Alkyds can be modified (blended with ) acrylic resins/emulsions or other polymers such as phenolic resins or urethanes, so all acrylic alkyds are modified alkyds, but not all modified alkyds are acrylic alkyds. Both are pretty general terms, but modified alkyd is much more vague and proprietary. The term "Acrylic Alkyd" is usually reserved for alkyds which have been chemically modified with acrylic monomers such as methyl methacrylate, methacrylic acid, styrene, vinyl toluene, etc. These acrylic monomers are incorporated into the alkyd molecule by addition polymerization. Such alkyds are generally characterized by faster solvent release, quicker tack-free time, better hardness, blocking resistance, color and color retention, and durability, depending on the choice of monomers and amount of acrylic content. These alkyds are also more expensive than conventional alkyds due to higher cost of monomers and the additional manufacturing steps required.

What is the difference between solid polymer and liquid polymer?
One is solid, one is liquid.A polymer is just a large molecule (macromolecule) made up of a chain of repeating structural units (monomers), and a liquid one would just be a liquid polymer. Any major differences would depend entirely on the specific polymer.
Why does old white plastic turn yellow?
While plastic is usually considered an "artificial" material, it is typically a polymer based on organic petrochemical compounds. Polymers can be described as large molecules made up of simple repeating units. The word polymer is derived from the Greek words poly meaning "many" and mer meaning "part". Many types of polymers can be created by varying the molecular composition of the repeating unit. Being organically-based, polymers are therefore subject to degradation and breakdown through natural oxidisation. Degradation may be initiated or accelerated by numerous factors including ultraviolet light, visible light, ozone, pollutants, manufacturing impurities, oxygen, and heat. During degradation, oxidisation can result in the breaking and rearranging of chemical bonds along the polymer chain. This can begin even during the manufacturing process, due to the conditions of extreme heat or pressure that may be used to form the polymer. To delay the onset of degradation as long as possible, both process stabilisers and long-term stabilisers are added to the polymer. The most important primary anti-oxidants used for long-term stabilisation are the sterically hindered phenols. Unfortunately, these exhibit an undesirable side effect when exposed to ultraviolet radiation. They develop deeply coloured molecular structures resulting in irreversible yellowing of the plastic. To minimise this effect, polymers are also provided with an ultra-violet stabilisation package. This package is often made up of ultraviolet absorbers (UVA) and hindered amine light stabilisers (HALS). UVAs protect physically through molecular absorption of the high-energy fractions of sunlight. The absorption transforms the molecule into an excited state, and when it collapses back to its original state, the absorbed energy is released as a thermal emission (heat). In contrast, HALS protect chemically by combining with oxygen when exposed to sunlight to form stable nitroxide radicals. These trap the oxidising free radicals released when the polymer is exposed to ultraviolet radiation. Eventually, the stabilisers are either consumed or migrate to the surface of the polymer where they are abraded away. The polymer has then lost its protection and deterioration proceeds rapidly when exposed to the factors mentioned above. In theory, after-market protectorant products provide a coating to replace or supplement the original UVAs or HALS in the polymer. They cannot, however, reverse any yellowing which is the result of degradation of the sterically hindered phenols within the polymer itself.
Difference between acrylic latex and alkyd paint?
The solution in which the pigment is suspended. i.e. the pigment is suspended in a water-based solution in latex paint, but in an oil-based solution for alkyd (oil) paints.
Can you use acrylic paints over a canvas primed with alkyd?
Yes. Cover the Alkyd Surface with Liquitex Clear Gesso first, then paint in acrylic. I've done this before with no ill effects whatsoever.
What is the difference between alkyd latex and waterborne alkyd?
Traditionally, alkyds are found in solvent-based paints that must be reduced with paint thinner or mineral spirits. "Waterborne alkyd" is a generic term to refer to an alkyd resin that can be used in a water-thinnable paint. Because alkyds are not miscible with water, a chemical modification is sometimes used to produce a hybrid alkyd resin - often acrylic/alkyd or urethane/alkyd - that is compatible with water. These hybrids are often categorized generically under the term waterborne alkyds. A pure alkyd can be emulsified in water using appropriate surfactant combinations. This type of surfactant-stabilized alkyd emulsion has been sometimes referred to as an "alkyd latex." Different resin manufacturers use varying terminology to describe waterborne alkyds with the terms alkyd emulsion, alkyd dispersion, and alkyd latex being among the most common.
Can you paint over xim peel bond with an acrylic paint?
Yes, you can paint over XIM with any acrylic or alkyd paint. Read the instructions on the can for drying and recoat times.
What is the difference between acrylic enamel and enamel?
Enamel paint is oil or alkyd. Alkyd paint is probably the most well known type of oil paint available on the market. The word alkyd actually refers to the synthetic resin used as a binder in the paint. This would be the oil in the paint, most commonly vegetable oil. Alkyd paints also come in a wide variety of finishes making it ideal for multiple different projects. Alkyd paint is very resistant to normal wear and tear. Thus, this type of paint is used commonly in "high traffic" type areas. This would include doors and trim within a home and also items that would need painting in the kitchen and bathroom such as cabinets. The alkyd paint will hold up to all the abuses that may come its way. Acrylic enamel is a water based full gloss usually for interior surfaces only. The gloss is nearly as high as gloss enamel but it is not quite as durable. One advantage is that if you are using white it does not discolor over time as much as alkyd based enamel. Also from a professional point i have never found the finish to be as good as enamel with less than three coats.
Which is better alkyd stain or oil based stain?
There is no difference. They are one in the same.
What is Alkyd Primers?

Can you mix alkyd enamel with industrial alkyd for metals?

What is the difference between wood paint and alkyd paint?
Alkyd paint has a resin in it to help the oil in the paint dry faster, oil based paint in my opinion has a more vibrant colors, both in depth an brightness, waterbased seems to be toned down some-what. Wood paint can be either water based or oil based and even water soluble oil based. Oil based alkyd paint lately are used for things or areas that might receive abuse, and because of the slower drying time the oil based alkyd paint will show less brush marks then water based paint.
What is styrenated alkyd resin?
It is a fast drying alkyd which is made by reacting the fatty acid, conjugated double bonds, in a Diels-Alder type reaction, with liquid styrene monomer. It sets up very quickly to become handleable, then dries a normal alkyd. They have good adhesion to aluminum and acrylic plastics. They are used to make hammered finishes , because they are usually in Xylene. There is a sister resins made by adding vinyl toluene, which are in an aliphatic solvent. They both have a specific re-coating window of under 4 hrs .
How do you paint with alkyd?
In the past oil paints referred to either petroleum based paints or linseed based paints. Today in the USA petroleum based paints are no longer sold and it is difficult to find linseed based paints though they do exist with a small proportion of linseed oil. Alkyd paints are made with synthetic oil and are readily available and have come to be known as "oil" paint.
What is an alkyd?
Alkyd is used to create paints that will dry extremely hard and will resist multiple cleanings. Normally, alkyd paints are oil-based, but there are now water based varieties. You can find alkyd paints on doors and trim both inside and outside houses.
