Storage and Handling

At temperatures up to 25°C storage stability packed in original containers amounts to at least 365 days.. When handling and processing epoxy resins and hardeners, the rules and regulations established by local authorities should be observed. A Material Safety Data Sheet is available on request.

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.
