COLOURS AND GLOSS RAL 1001 beige - High gloss BASIS PROPERTIES (AT Density Solid content Recommended d.f.t. Dust dry after Full cure after Recoating interval 23˚C AND 50% R.H.) : approx. 1,3 g/cm3 : approx. 59 % (volume) : 35 - 50 µm (dry), depending on application : approx. 30 minutes : approx. 7 days, see additional information : min. 24 hours, see additional information max. unlimited, provided gritpapered, clean and dry Shelf life : separate components, stored cool an dry in original packaging, minimum 12 months Flash point (DIN53213) : Double Coat Modellak base component 44 oC Double Coat Modellak hardener 1 oC SPREADING RATE At 35 µm (d.f.t.) : 12,9 m2/kg (14,8 m2/l) At 50 µm (d.f.t.) : 8,6 m2/kg (10,4 m2/l) The practical spreading rate depends on a number of variables, such as: shape and size of object to be painted, the condition and profile of the substrate, the method of application, climatologic conditions and skill of labour. SUBSTRATE CONDITION AND TEMPERATURE All substrates : clean and dry, in good condition, free from any contamination and loose particles, degreased with Double Coat Degreaser and pre-treated with IJmopox ZF primer/IJmopox HB coating, Poltix Sprayfiller or IJmofix and sanded with grit paper P300-320; During application and curing a minimum temperature of 15 ºC is allowed. The temperature of the substrate should be minimum 3 ºC above dew point. INSTRUCTIONS FOR USE Before use, mix base and hardener components thoroughly. Mixing ratio : 67,0 base : 33,0 hardener (by weight) 63,0 base : 37,0 hardener (by volume) Do not prepare more material than can be applied within the pot life of the mixture.

DOUBLE COAT MODELLAK Resistance to styrene Double Coat Modellak is recommended for models used to produce moulds for the GRP industry. For this specific application it is imperative that all materials used in the paint system for the model resist styrene. When a component does not resist styrene, this can lead to serious surface defects in model or mould. SAFETY INFORMATION See the corresponding Material Safety Data Sheet for detailed instructions on safety, disposal and health. Date: October ’11 422-99999 Disclaimer Although the information and recommendations are presented in good faith...
