BECKOPOX™ EP 301 is the most commonly used of solid epoxy resins. Compared with the higher molecular weight BECKOPOX™ grades EP 304, EP 307 and EP 309 it has the lowest viscosity and the lowest epoxy equivalent weight. The resin is used mainly in solvent based cold-curing coating systems.

- Special Properties and Uses
Type 1 resin for solventborne coatings, anticorrosion primers, additional binder for stoving paints, e.g. based on saturated polyesters or acrylates.
- Suggested Uses and Processing Information
BECKOPOX™ EP 301/75X is an unmodified epoxy resin with a relatively low melting interval, which finds use primarily in solvent based two-component coatings. When used in cold-curing and heat-curing coating systems the resin is preferably cured with polyamines, polyamidoamines or amine adducts. Respective the curing agent used impact-resistant films with high chemical and corrosion resistance can be obtained.
Important uses are:
- anticorrosion primers
- zinc galvanzing paints and
- high durability coatings
In addition BECKOPOX™ EP 301 in solution together with suitable hardeners is used for the pre-impregnation of textile glass fabric for manufacturing low and high pressure composites.
Two-component coating systems
When formulating solvent based coatings BECKOPOX™ EP 301 is mainly cured with polyamidoamines such as BECKOPOX™ EH 651 or with polyamines, e.g. BECKOPOX™ EH 631, EH 624 or EH 625.
To formulate cold-curing low solvent (high solids) systems it is recommended to use some quantities of the liquid resin BECKOPOX™ EP 116 or BECKOPOX™ EP 140 along with the respective Beckopox hardener in the formulation.
Adhesives
BECKOPOX™ EP 301 together with liquid epoxy resins such as BECKOPOX™ EP 140 and suitable curing agents give high strength adhesive bonds.
Curing with isocyanates
In some special cases it may be of interest to use BECKOPOX™ EP 301/75X as combination partner with other resins in a two-component system using an isocyanate for crosslinking. The hydroxyl value of BECKOPOX™ EP 301 (100%) is approx. 120 representing a hydroxyl content of approx 3.6%.
Stoving systems
In combination with saturated polyesters or thermosetting acrylates, BECKOPOX™ EP 301 improves chemical resistance and adhesion on various metals. A minimum stoving temperature of approx 150°C should be achieved.
