Tputty™ 502 is the best material for applications where large tolerance
differences create the need for compression of the interface material beyond
50% of its original thickness.
Tputty™ 502 will flow and ensure low pressures on the components being
cooled. In conjunction with outstanding compression characteristics, Tputty™ 502
has a high thermal conductivity, resulting in very low thermal resistance.
Tputty™ 502 is naturally tacky and requires no additional adhesive coating that
can inhibit thermal performance.
