Q-CEL® spheres are hollow and inorganic and can be used as a low-density additive for Polyester and epoxy boat putties. The addition of Q-CEL hollow spheres, alone or in combination with other mineral fillers, effectively increases the volume of the mixture while decreasing the weight and cost per unit volume.
Boat putties formulated with hollow spheres are smooth and spread easily. They can be applied to vertical surfaces without sagging or slumping. They cure rapidly and uniformly. When cured, they are non-absorptive, relatively strong and resist crushing. Marine putties filled with hollow spheres show low shrinkage and are easily sanded, drilled and sawed
