​則附著力和耐蒸氣性能提高,但塗膜泛黃性增強,成本提高,如果氨基樹脂比例過多,則塗膜變脆。因此要根據印品的要求,經過試驗合理選擇三者的比例。

金屬印刷白墨以椰子油醇酸樹脂、環氧樹脂和氨基樹脂為連結料,與鈦白粉整色劑經混合研磨而成,經高溫烘烤也不泛黃,在金屬印刷中被廣泛使用。

醇酸樹脂對顏料的潤濕性能較好,塗膜的附著力和柔韌性良好,拼用環氧樹脂以提高附著力、耐沖擊和耐蒸氣殺菌性能,氨基樹脂作為固化劑促進醇酸樹脂、

環氧樹脂的交聯固化,並提高塗膜的硬度和光澤。一般來說,增大醇酸樹脂的用量,塗膜的耐化學品性和附著力下降;增大環氧樹脂用量,

則附著力和耐蒸氣性能提高,但塗膜泛黃性增強,成本提高,如果氨基樹脂比例過多,則塗膜變脆。因此要根據印品的要求,經過試驗合理選擇三者的
比例。

在膠印機上印刷的墨膜很薄.大約3um左右,至少要印23次才能達到理想的白度因此生產效率比較低,印刷成本較高。

鈦白粉的用量要恰當,一般白塗料的鈦白粉含量為30%-50%,但在金屬印刷白墨中鈦白粉含量應略大於50%。鈦白粉的用量過多,雖然塗膜的白度和遮蓋力較好,

但印刷性
能和塗膜的為了提高金屬印刷白墨中白塗料的白度,往往加入微量紅、藍顏料作為整色劑以調整色相,整色劑的用量為0.01%-0.03%

採用豆油醇酸或脫水蔗麻油醇酸樹脂為基料,可製成低溫固化型金屬印刷白墨,添加少量催乾劑或氨基樹脂以調節乾性,這種白墨適用於蒸氣烘房,

烘烤溫度
90-120℃,般用於印刷無須高溫殺菌的馬口鐵製品,如茶葉罐、糖盒,餅乾罐等。
