Designed for use on glass, ceramics, anodised aluminium, primed metals, timber, plastics and much more, the HA6 is perfect for use in aquarium construction, as well as for the manufacture of in-situ gaskets and seals for pumps and pipework to prevent water and dust ingress. Its excellent weatherproofing properties also make it ideal as a seal for cabinets in dirty environments or external applications.
