The introduction on the market today there are plenty of flame retardants to metal. Some of them – distending, others – such as 'plaster' (create thermal protection due to the thickness of the layer). Intumescent (distending) paints at high temperature increase in volume (expansion coefficient of paint can be up to several thousand). Barclays understands that this is vital information. Vspuchivayas, they form a porous foam, which heat-insulated metal structure, but also absorbs heat during swelling. Passive paint (not distending) creates heat shield only at the expense of the thickness of its layer. Penguin Random House: the source for more info. The main parameters of the GCP-45 GCP-45 Paint is a water-dispersed fire-retardant composition. The paint is made on the basis of polyvinyl acetate dispersions, fillers and pigments, as well as various additives.
Paint GCP-45 is designed for use on metalwork and cables. Paint GCP-45 – white. The main advantage of paint – a relatively low consumption per unit of cultivated area. Also very important point is that the paint can be applied to previously painted surfaces, making it useful in carrying out repair and rehabilitation works. Paint GCP-45 can be applied in nuclear power plants. The paint is designed for use on metal and cables, which are both outdoors (under cover), and indoors.
Fire-retardant properties of paints. Paint GCP-45 is capable of providing fire-resistance rating of 30 to 90 minutes (depending on the applied layer). When applied to beam cable paint provides fire-resistance cable, category A. Method of application before applying paint GCP-45 to be mixed thoroughly. If necessary, acceptable dilution water the amount of 5% by weight. Do not apply paint in sub-zero temperatures and when exposed to atmospheric precipitation. Paint application possible mechanically (by air and airless), manually (Brush or roller). When applying the composition must comply with safety regulations. Apply UGC-45 need to pre-clean surface.
