Keep in mind that during storage (or shipping) material outdoors in cold weather, it may take up to 24 hours to ensure that the components reach room temperature. The optimum temperature of the molding should be 20-250C and humidity no more than 50% .For mixing, use a clean, dry container. Thoroughly stir the mixture for 3-5 minutes, occasionally scraping on the sides and bottom of the container. ★ Recommended by plant percentage (%) of the curing agent is 2,5-3%. ATTENTION!!! Obey the amount of catalyst, hardener over the recommended rates (2-3%), increases the stated percentage of shrinkage silicone and has a negative impact on the physical and mechanical properties, but reduces the curing time.
