High Quality Kemco Precision Impression Compo from UK
 
Kemco Impression Compound is a thermoplastic material which softens when heated and hardens when cooled, providing an accurate full or partial impression.
Each disc measures 82mm diameter x 7mm depth.
A major advantage of impression compound materials is that they are very easy to adjust. Alterations to the impression can be made by removing replacing or adding material until a satisfactory result is obtained. This helps achieve an accurate impression.
