|
|
I'd like to display some specimens inside transparent plastic boxes, and I would glue each specimen inside its box (so that the specimen won't move even if the box is shaked around or turned upside down).
My criterias for the adhesive material are as follows:
-colorless (and doesn't turn yellowish with time)
-water-free and non acidic
-easily removable with acetone
-providing a strong hold (for specimens which are 6 to 8cm in size)
What type(s) of glue would match those requirements?

Adam Wright of the crocoite Adelaide mine has been attaching delicate specimens for years to the inside of clear acrylic boxes - these boxes are not always airtight but could probably be made so. he uses one adhesive that is soluble by acetone and also hot glue which is soluble in alcohol.
maybe best to contact him:

i found some closeup photos of Adam's mounted specimens. he also uses hot glue which can be removed via warm alcohol but may yellow with age. He mounts these mainly for protection and it's up to the new owner to decide if he wants to remove the specimen for final display - although his displays are fine with me and not worth the risk to handle them further.

I'll send an email (although I'd go with a little less glue)

yah - but don't forget that Adam is shipping these from Tasmania to Tucson. i guess i would over-do the glue on these wonderful and expensive specimens also.

I will recommend you Paraloid B72. Paraloid B-72 is an Acryloid (copolymer of ethyl methacrylate and methyl acrylate). The secret for it's strength is to leave it to dry for 24 hours. It has all the criteria that you are looking for
