＜評価＞
１．パンクシーリング剤中の酸素濃度
パンクシーリング剤をステンレス容器に充填してから６０分後に、ステンレス容器内のパンクシーリング剤中の酸素濃度を、島津製作所社製、溶存酸素計ＤＯ１４２を用いて測定した。下記評価基準により評価した。なお、許容範囲は○と◎である。
−評価基準−
◎：パンクシーリング剤中の酸素濃度が２ｍｇ／Ｌ未満
○：パンクシーリング剤中の酸素濃度が２ｍｇ／Ｌ以上４ｍｇ／Ｌ未満
△：パンクシーリング剤中の酸素濃度が４ｍｇ／Ｌ以上５ｍｇ／Ｌ未満
×：パンクシーリング剤中の酸素濃度が５ｍｇ／Ｌ以上 <Evaluation>
1. Oxygen concentration in puncture sealant 60 minutes after filling the puncture sealant into the stainless steel container, the oxygen concentration in the puncture sealant in the stainless steel container was measured using a dissolved oxygen meter DO142 manufactured by Shimadzu Corporation. Evaluation was performed according to the following evaluation criteria. The allowable ranges are ○ and ◎.
-Evaluation criteria-
◎: punk oxygen concentration in the sealing agent is less than 2 m g / L ○: puncture sealant oxygen concentration is less than 4 m g / L or more 2 m g / L of △: oxygen concentration in the puncture sealing agent 4 m g / L or more 5 m g / L less ×: oxygen concentration in the puncture sealing agent 5 m g / L or more

Claims
