Alkyd Oil Paint made with Modern Technology
Environmental VOC requirements pushed paint manufactures to be creative and innovative. Protek Paint has risen to be a leader in VOC compliant paint.
The Beginnings of Alkyd Oil Paint
Typically, alkyd paint used for the home or for industrial finishes consists of the oil-modified polyester to form the coating film. A solvent such as mineral spirits was commonly used to help with flow and leveling in application. Metal naphthenates are used to catalyze the drying reaction. Various pigments are used to provide hiding power and color development for the surface being painted.
Alkyd Started in the 1930’s
Although they are called oil-based, many times they are not based on oil, as the name implies. More directly alkyds, or alkyd resins, come from a complex network of polyesters that are the results of development work started in the 1920’s by General Electric to coat over the windings of the electrical motors. This became a staple for the paint industry. These resins are the combinations of dicarboxylic acids or their anhydrides and polyfunctional alcohols, from where the name originates. Alkyd is the chemical abbreviation for alcohol (alkyl).
The Origin of Resin
The origin of the resin is the polymerization reaction which occurs between alcohol, such as glycerol, and a dicarboxylic acid or its anhydride. Often phthalic anhydrides are used along with glycerol and allowed to react to form the polyester glyptal. Glyptal was the name General Electric used for its commercially developed resins for the paint industry.
Types of Oil Mixture
Various types of oils are used for various desired outcomes. The percent of the oil also plays a factor in the desired outcome. Alkyd coatings are typically sold in three classes: long, medium, and short. These terms represent the oil length (chain stopped) in the resin.
Long-oil alkyds normally contain 60 percent fatty acid.
Medium-oil alkyds normally contain 40–60 percent fatty acid.
Short-oil alkyd contains less than 40 percent fatty acid.
Regulations have restricted the continued use of alkyd resins in homes. These have been replaced largely with polyester for industrial applications. By name alone within the paint industry, this indicates a polyester, free of natural-oil modifiers. These polyesters are used extensively today in coatings.
Alkyd Oil Paints use Today
Today the focus for alkyd oil paints is metal, mainly for industrial applications such as finishing coats for trucks, trailers, railings, and metal trim, to resist rust and give protection. Rust inhibiting enamels have many uses plus fast-drying properties. Fast drying is normally referred to drying times of less than 1 hour. Alkyds normally dry in various times from 1 hour to 10 hours. Some alkyd paints can be used as primers in combination with either Red Oxide or Zinc Oxide (Zinc Rich). Many are used for the adhesion and flexibility or hardness and can be combined with other resin systems to improve these properties.
Protek Shield Fast Dry Alkyd
High-performance alkyd/acrylic solvent-based industrial enamel can be used mono-component or bi-component (used out of the can or with an additional catalyst). The addition of the catalyst to this mixture improves chemical resistance, chip resistance or flexibility and gloss retention.
Used straight out of the can, this product has excellent adhesion and an extremely glossy surface. Corrosion inhibitors help to make it resistant to rusting. It dries to the touch in around 30 minutes at 70F and lower relative humidity. Although it can be applied with a brush and roller, best results are achieved with a spray application. This product was developed for the professional applicator in mind for both application and performance.
- Higher temperatures may accelerate the dry, and humidity and colder temperatures will slow down both the dry and cure of the product.
- Higher solids leave behind a very good build of product and thereby deliver higher performance.
- Very low VOCs, as we use solvents that are known not to harm the ozone layer.
- Specific colours have been developed for name brand industrial tractors, earth moving equipment, and other manufacturers.
Neutral base to make other bright or dark colors
VT Alkyd Fast Dry (Vinyl Toluol)
This is a quality alkyd solvent-based product with corrosion resistance and a gloss finish. It is a true work-horse product because of the ease of use in most applications. Use when lighter and medium performance is required.
It’s easy to apply with brush, roller or spray, and can be used with mineral spirits for thinning or clean-up. It dries to the touch in just over an hour at 70F with low relative humidity. Warmer temperatures normally speed up the dry and cure but cooler temperatures and higher humidity retard both the dry and cure times.

Rust Inhibiting Enamels
The finest corrosion inhibiting enamels available in a gloss finish, are corrosion resistant for additional life and have a superior lasting finish on valuable metal surfaces.
Various tint-able colours from a neutral base
Urethane/Alkyd Floor Enamel
Blend of alkyd and urethane for a durable glossy floor coating. Ideal for your basement or for light to light/medium use industrial floors.
This paint can be colored from light colors to medium shades from one nuetral base.
PROTEK PAINT was founded by an Alkyd Oil Resin maker and our Alkyd Oil Flat is the finest Alkyd Oil Flat, primarily used for stucco ceilings. It has a very high hiding White with a very good body that spreads to a beautiful finish. Using the lowest odor solvent currently possible, our Flat Alkyd Ceiling Enamel is one of the finest products available today, as it always has been.
Using Alkyd Oil Paints
Due to changes in the Canadian law, oil-based exterior alkyd paints are only allowed on metal products, because an alkyd oil paint medium is very tough, with high adhesion and great hiding power due to higher solids. Most often, this oil-based alkyd paint tends to be an industrial application for machinery, heavy equipment, and pumps. It is used on certain consumer products such as bicycles, and the iconic red wagons, plus all types of residential and commercial metal railings.
The way paints are manufactured today, there is no need for oil alkyd paint thinners. The same can be said for oil-based interior and exterior alkyd paint.
Traditions is a Hybrid Alkyd Oil Paint
Traditions Gold is amongst the best quality paints on the market today, utilizing the latest technology, which comes from soya bean oil, a renewable resource. This allows us to utilize the development of products that could give some of the properties of a typical alkyd but without the use of traditional solvents. This lead to the development of Hybrid Alkyds that used water as the solvent.
With the introduction of legislation to reduce the use of solvents over the last 20 plus years, many alkyd oil paints needed to reduce their Volatile Organic Compounds (VOCs). Traditions Gold combines a conventional highly durable alkyd oil and emulsifying it in water to obtain a remarkable durable finish that is combined with a urethane and the finished product is environmentally friendly.
This is the first of two very distinctive product lines, in honour of our Rogers’ family tradition of making the finest quality paints and in celebration of our 65th anniversary of PROTEK PAINT.
TRADITIONS HAS GREAT DURABILITY & VERY LOW VOCs
Traditions Gold can be used on the interior and exterior of the home. Due to the tough durability, but little or no odour, it can be used on tough wearing areas such as interior and exterior wood trim, cabinets, and doors. This is due to its superior adhesion and scrub-ability.
Extremely low VOC for a Safer Home & Environment
To meet universal environment regulations for low VOCs, Alkyd Paints can be made water-reducible by the addition of free acid groups to the molecules. In the presence of a base such as ammonia, these groups allow the polymers to be solubilized in water rather than in organic solvents.
Usually a co-solvent such as 2-butoxyethanol is necessary to maintain a stable solution, and under these conditions the ester linkages that are the basis of the alkyd polymer chain are vulnerable to breakage by hydrolysis. In this case special monomers are often chosen to give the chain hydrolytic stability. VOC levels are 20 to 30 grams per litre but give a very long-lasting coating for the customer. Changes in the legislative use of solvents require most products to increase their solids or use compliant exempt solvent for a safer environment.
Other Alkyd Oil Paint Products
Again, due to VOC regulation changes, many innovations have been made and Protek Paint continues to develop innovative solutions to help to leads the way, as shown by the products below, whether manufactured by Protek Paint or distributed.
These varnishes are VOC compliant and are used today for floors and furniture instead of alkyd oil clear coats. Solvent-based varnishes normally ‘yellow’ more over time.
Protek Paint distributes this product line that uses alkyd hybrid technology to replace alkyd oil stains.
We manufacture this product, which replaces alkyd oil wood primers and alkyd oil paint primers. Our primer will adhere to previously painted oil-based surfaces.
Alkyd Oil Paint Manufacturing
Protek Paint was founded in 1950 and the first paint we manufactured was an Alkyd Oil paint brand using an alkyd resin manufacturing process. This manufacturing tradition is still alive in our Alkyd Flat paint brand aimed at stucco ceilings. However, our manufacturing energy has turned towards our industrial products such as Protek Shield & VT Fast Dry products plus Rust Inhibiting Enamels.
We also manufacture Traditions Gold using the latest hybrid technology, soya bean oil, a renewable resource. This allows us to produce a Hybrid Alkyd paint with great durability that is soluble in water and has low VOC’s. With these manufacturing skill sets accumulated over the past 70 years, you can give us a call to discuss your industrial coatings or manufacturing paint requirements.
