oil length

oil length

[′ȯil ‚leŋkth]
(materials)
The ratio of oil to resin in varnish; expressed as gallons of oil per 100 pounds (45.3 kilograms) of resin.

oil length

In a varnish, the number of gallons of oil per 100 lb of gum or resin.

The viscosity can be reduced by decreasing the molecular weight of the alkyd resin by changing the dibasic acid/polyol ratio or by increasing the oil length.
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.
In all the examples mentioned above, low VOC was achieved through chemically or physically modifying the alkyd resin--reducing molecular weight, increasing the acid value and neutralizing, increasing the oil length, or adding a significant amount of surfactant--all of which cause a reduction in overall alkyd performance.

The drying characteristic of the resulting polymer is dependant on the oil length of the polymer (more oil, slower drying) and the amount of unsaturation that is present in the corresponding oil.
The correct HLB should be selected based on the emulsification temperature, the polymer charge density, and the polarity of the resin, which is determined by the acid number, oil length, and hydroxyl value.
Another goal of the study was to determine how versatile this particular modification was for different oil length alkyd systems.
Traditional methods to increase solids such as reactive diluents (3) or increasing the oil length decrease Mn, which has a detrimental effect on dry times, final coating hardness, and humidity resistance.
Additional reductions in resin viscosities were achieved by increasing the oil length to 65 and 70% but this also resulted in a decrease in Mn to below 3,500.
