Solvent-based removal of adhesive tape
A summary of Dstl鈥檚 research into the effect of solvent-based removal of adhesive tape on subsequent fingermark visualisation processes.

Details
Solvent-based adhesive tape removal is listed as a Category B process in the Fingermark Visualisation Manual (FVM). This is because it could be useful where adhesive surfaces cannot be easily separated using Category A methods (such as, pulling and prising). It is known that some solvents can soften the adhesive if used carefully, but it is not fully understood if the process is detrimental to subsequent fingermark recovery. To investigate this Dstl carried out a planted fingermark study to assess the impact of 4 solvents:
- Un-du庐 Volatile Organic Compound (VOC) Compliant
- HFE 7100
- Heptane
- Ethanol
