In　this　study,　all　experimental　investigation　is　made　of　the　anti-frosting　performance　of　our　newly　developed　anti-frosting　paint.　By　coating　the　paint　oil　a　cold　metal　Surface　the　onset　of　the　frost　formation　may　be　delayed　at　least　15　min　and　the　thickness　of　the　deposited　frost　layer　may　be　reduced　by　at　least　40%　and　thus　the　weight　of　the　deposited　frost　may　be　reduced　by　more　than　40%　compared　with　that　on　the　uncoated　copper　surface.　Under　some　preferable　conditions　(air　relative　humidity　＜　60%,　cold　plate　surface.　temperature　＞　-10　similar　to　degrees　C),　the　coating　surface　can　be　kept　free　of　frost　at　least　for　3　h.　(c)　2005　Elsevier　Ltd　and　IIR.　All　rights　reserved.
