CrysPack refined its Gel chemistry to provide a range of retention levels . The standard retention levels^* available are: L, M, H.

  The optimum tack level for individual devices is dependent on material type, surface roughness, size, thickness and weight.The general guidelines are low tack level (L) and medium tack level (M) for polished surfaces or etched surfaces, and high tack level (H) for rough surfaces such as side faces.

  * Other retention levels can also be required if you have such requirments.
