上記で用いた各成分のSP値(溶解度パラメータ)を、論文(R. F. Fedors: Polym. Eng. Sci., 14 〔2〕, 147-154 (1974))に記載の凝集エネルギーEおよびモル分子容Vを用いてFedors法から求めた。
分子全体の凝集エネルギーΣE=各構成原子団の凝集エネルギーEをモル比で加重平均したもの
分子全体のモル分子容ΣV=各構成原子団のモル分子容Vをモル比で加重平均したもの
構成原子団CH2の上記論文記載値は、凝集エネルギーE=1180(cal/mol)、モル分子容V=16.1(cm3/mol)
分子全体の凝集エネルギーΣE=1180×1=1180(cal/mol)
分子全体のモル分子容ΣV=16.1×1=16.1(cm3/mol)
SP値=(1180/16.1)1/2=8.56(cal/cm3)1/2

分子全体の凝集エネルギーΣE=1180×(1/3)+820×(1/3)+1125×(1/3)=1042(cal/mol)
分子全体のモル分子容ΣV=16.1×(1/3)-1.0×(1/3)+33.5×(1/3)=16.2(cm3/mol)
SP値=(1042/16.2)1/2=8.02(cal/cm3)1/2

得られた塗膜層を用いて、下記の評価を行った。結果を表1に示す。
測定対象は、-20℃の環境下において、塗膜層に付着した氷塊を移動させるために要する力であって、便宜上、本明細書では、この力の大きさを「着氷力」と定義した。
まず、円柱状の氷塊を作製した。氷塊は、スチロール角型ケース16型(アズワン社製)の底面にステンレスリング(内径25mm)を置き、そこに6gの純水を注ぎ込んで-20℃で16時間以上凍結させ、凍結後にステンレスリングを除去することによって作製した。
アルミニウム箔:A1N30(竹内金属箔紛工業製)上に作製した引張強度測定用塗膜をアルミニウム箔と共に2cm×15cmの長方形に裁断して、両面テープ(日東電工株式会社製、品番:No.5000NS)を用いて15cm×15cmのアルミニウム板(株式会社久宝金属製作所製、品番:M9502)に貼り付けてサンプルを作製した。
アルミニウム箔:A1N30(竹内金属箔紛工業製)上に作製した引張強度測定用塗膜層をアルミニウム箔:A1N30(竹内金属箔紛工業製)から剥離して、1cm×6cmの長方形に裁断してサンプルを作製した。引張試験機(株式会社島津製作所製、オートグラフAGS-50NX)によって、20℃環境下においてつかみ具間距離2cm及び試験速度300mm/分の条件下で得られたサンプルの引張強度(N/mm2)を測定した。
