Epoxies are issued in liquid and solid state. They are termoplastichna, but under the influence of different hardeners turn into not fusible polymers which find broad application in the industry as material for gluing together, germetizator and so forth. Process of hardening of these pitches can happen at standard room temperature to 20 °C.
ED - 20 epoxy represents transparent viscous liquid of yellowish color without visible mechanical inclusions.
ED - 20 epoxy - two - component pitch. For its hardening hardeners for epoxies are required (PEPA, TETA, etc. ).
Features of ED - 20 of use
ED - 20 epoxy has wide range of application and has number of features:
- it is not recommended to use the structures containing only epoxy and hardener as very rigid materials subject to treshchinoobrazovaniye in most cases turn out;
- in comparison with acrylic resins, epoxies possess bigger toxicity;
- low - elasticity. At the movement of surfaces under epoxy coating, there can be crack;
- ED - 20 epoxy rather vyzky therefore during the work it is necessary to use different solvents often.
There are two ways of temporary lowering of viscosity of pitch: one represents mix heating, and the second - addition of solvent to it. In both cases pitch becomes more fluid. Pitch with light body more tekuch, is simpler to put it with brush or the roller, it quickly impregnates fiber glass fabric and more deeply gets into porous surfaces like the damaged decay of wood.
