A study on the reactive diluent for the solvent-free epoxy anticorrosive coating

Abstract

Solvent-free epoxy anticorrosive coatings have the features of environmental protection, security, economy and chemical resistance. It is important to protective steel structure engineering in sea or chemical and petroleum.The affect of the different kinds and amount of reactive diluent(660A, 90, 3601, 6360) on the amount of non-volatile matter, viscosity and impact strength of coating film. From the experiment analysis, it was found that the dilution capability of different kinds reactive diluent is single functional short chain660A>monofunctional long chain90 >bifunctionality3601>Three functionality6360;The effect of reactive diluent on the amount of non-volatile matter is 3601≈6360>90>660A; The effect of reactive diluent on the impact strength of coating film is3601> 90≈660A>6360. From the amount of non-volatile matter and impact strength of coating film, it was found that 3601 as eventually reactive diluent, the most appropriate amount of 3601 is 12%.
