Abstract: In the present study the effect of weight percentage of nanoclay with epoxy resin
coating on mechanical properties ( impact strength , hardness, and wear rate ), Adhesion test
and thermal properties (thermogravimetric analysis (TGA), thermal expansion coefficient
(CTE),the weight percentage of nano clay at ( 0,1,3,5,7) wt% ,has been investigated.Results
indicated,that when increase the weight ratio of nano clay the value of impact strength
increased, hardness and decreasing wear rate up 5wt% , and at 7 wt% that the impact strength
, hardness would be decreased and wear rate increase due to agglomeration of nano clay . The
strength adhesion pull off of the epoxy coating was 1.76 Mpa ,when adding nano
clay,improve the adhesion properties of the epoxy coating at the ratio of 5%. The improved
the thermal stability of the nanoclay filled with epoxy coating. Thermal stability is very
important for coating materials.
