this sounds an awful lot like the mounting media you can purchase thru Newcomer in order to perform the "tissue transfer technique"
The product is called Mount Quick catalog # 6270A and I believe it comes from Japan.  It costs about $12.00/tube.
Newcomers phone # 800-383-7799.
The product is great!  It has helped me out many a time.
