Element B, used together with the resin Element A. Content: 1 KG It is used together with Resin Ref. 21.270.2 Recommendations: - Try to keep the PU bottles in a place with suitable atmospheric conditions to maintain their chemical properties. - Make sure that the bottles are tightly closed after each use. - Element B polymerizes with air and acquires a sticky consistency, so after each use dry the pouring area well. - The water in the PU mixture gives rise to carbon dioxide that makes the foams expand. Very little water is enough to create gas. - The temperature plays an important role in the viscosity, if it is very cold the viscosity decreases and the components will unite more slowly = the process slows down. - Before reusing the stored product, we must remove the inner liquid.
