Sphere.core S is a core material based on glass veil and characterized by fast and low resin consumption. It gets soft and shapeable when impregnated with resin and thus allows jointless overlapping and excellent bonding with the covering glass layers. It is also used to improve laminate surfaces as it eliminates print through of subsequent layers such as fabrics or core layers (i.e. PVC foam or balsa). It is mainly used in hand lay up process and for panel production.
