Special Properties and Uses

BECKOPOX™ EM 441 can only be used in combination with BECKOPOX™ EM 440 for good adhesive one-pack-stoving systems, e.g. primers with high corrosion protection, foil and packing lacquers. The elasticity of the system BECKOPOX™ EM 441/EM 440 is adjusted by variation of the mixing ratio.

Suggested Uses and Processing Information
  • BECKOPOX™ EM 441 is a modified epoxy resin which cures at high temperature. The resin system shows excellent adhesion onto most metal substrates, outstanding deep-drawing properties with good surface hardness, and corrosion protection. Due to this, BECKOPOX™ EM 441/EM 440 is preferably used in metal pre-coating systems like coil-coating or sheet-coating.
  • Important other applications are stoving primers for corrosion protection, coatings for machineries, conveyors, tanks, pipes, fuel containers, collapsible tubes, electro-insulation varnishes and foil lacquers which resist high temperatures.
  • The mixing ratio between BECKOPOX™ EM 441 and EM 440 can be between 1 : 1 and 6 : 1 (f.o.d.). Standard mixing ratio is BECKOPOX™ EM 441/EM 440 approx. 3 : 1. If the proportion of BECKOPOX™ EM 441 is increased, the flexibility of the resulting film increases too. Whereas if the amount of BECKOPOX™ EM 440 in this mixture is increased, the resistance against e. g. hot water improves, but flexibility declines. The system BECKOPOX™ EM 441/EM 440 can be modified with amino resins to increase curing speed but the storage stability of the resin mixture decreases at the same time. The system BECKOPOX™ EM 441/EM 440 (cured at temperatures around 200°C) is nonyellowing and can be pigmented with the usual pigments / fillers suitable for high-temperature stoving systems.

Acceleration of curing

Additions of approx. 1% BECKOPOX™ EH 610 (hardener), improves curing speed, especially at relatively low temperatures. The storage stability of this mixture is approx. 6 weeks only.

Dilution

Mixtures containing higher alcohols, acetic acid esters, ketones, glycol ethers and aromatic hydrocarbons are preferably used to dilute systems containing BECKOPOX™ EM 441/EM 440. An appropriate mixture consists of 40 parts xylene, 10 parts diacetone alcohol and 50 parts methoxypropanol. Aromatic solvents should not be used alone for dilution in order to avoid formation of a porous film with reduced anticorrosion resistance.
