Figure 4 shows the surface dry time and Pendulum hardness test results of several cobalt and manganese-based driers compared to the iron-complex drier in a long-oil alkyd resin.
In these tests, we chose a simple, clear alkyd formula based on a long-oil alkyd resin and used a drier package consisting of 0.04% cobalt and 0.1% calcium metal based on resin solids.
We compared Fe and Co driers in HS long-oil alkyd coatings.
The aim of our work was to perform a comparative study of commercially available Fe-bispidon driers and Co-octoate driers in air-dried HS long-oil alkyd coatings.
A soy-based long-oil alkyd
resin; a soy-based high-solids, long-oil alkyd
resin; and a linseed-based, high-solids long-oil alkyd
resin were evaluated in combination with the new reactive diluent at weight percentages ranging from 10% to 50%.
Vogel's paper detailed technology that has been developed to disperse short-, medium-, and long-oil alkyd
resins with minimal surfactant and no polymer modification.
Beckosol AQ 100 is a soya-based, long-oil alkyd
resin provided at 55% solids.
Resin Composition, Molecular Weight, and Polydispersity
In general, the shorter the oil length of the alkyd resin, the higher the temperature required; therefore, this technique is typically limited to medium- and long-oil alkyds
. The emulsions typically have low storage stability and inferior performance due to the presence of high levels of surfactant, which can also migrate to the surface of the coating and lead to early water resistance or corrosion resistance failures.
Available in several shades, timber oil is a combination of tung oil, linseed oil and long-oil alkyds
. In general, teak should be treated with oil-based formulas.
"Combined with the on schedule close of our Landskrona site in Sweden, where mainly long-oil alkyds
were manufactured, we are on track with our transformation to a more eco-friendly product portfolio."
One hundred percent solids systems have been around for a long time and date back to previous long-oil alkyds
. There are several chemistries used in 100% solids systems and I will separate them by the main curing mechanisms: oxidative cure, energy cure, amine cure, and hydroxyl/carboxyl functional two-component (2k) systems.
