Richie,

You are correct. I did browse around for information on this type of EVOSTIK and only fouund them available in UK in press type tubes rather than silicon gun type. I am sure that these are very commonly found also in the latter format as I do not think they would only do them for the local market only. Consequently, maybe we have not tried enough to find a source.
Luckily the local price is reasonable...approx $2.7 per tube.
