Alkyd Resins

Resins made by the union of dibasic acids, or anhydrides such as phthalic anhydride with a polyhydric alcohol such as glycerol.

Viscosity: May range from 100 cPs. to over 1000 cPs. depending on temperature and make-up of particular alkyd resin.

Remarks: Alkyd resins may be varied or modified by the use of other anhydrides, glycols, polyols, or other liquids, the most common of which are natural oils. Alkyd resins are easy to apply, retain their initial appearance after long exposure to weather and have good heat resistance, color retention, toughness, adhesion and flexibility. They are used as protective and decorative coatings for metals, wood, paper, textiles; are used in adhesives, printing inks, floor coverings; as vehicles in automotive and industrial finishes; and in oil and water paints, lacquers, and enamels.

Pump Notes: Construction recommendations depend on individual formulations. Mechanical shaft seals may be used depending on viscosity and temperature.
