埃夫卡EFKA4403和4406分散劑
埃夫卡EFKA–4403 防止顏料聚凝之高分子分散劑；以醇酸樹脂為分散樹脂和 EFKA–4403 為分散劑的通用色漿, 能有以下的優(yōu)點(diǎn): 1. 非常相溶于硝基系統(tǒng)至長油醇酸系統(tǒng)； 2. 容易進(jìn)入/加入其它樹脂系統(tǒng)； 3. 不會造成溶劑沖擊或樹脂沖擊； 4. *的防止聚凝； 5. •不會在zui終涂料里聚凝； EFKA–4403 特設(shè)計來配合以醇酸樹脂為通用分散樹脂的溶劑型低樹脂量通用顏料漿（微脂色母漿）.
埃夫卡EFKA–4406防止顏料聚凝之高分子分散劑。EFKA–4406 能穩(wěn)定無機(jī)顏料, 有機(jī)顏料和炭黑的高分子分散劑.這能給以以下的優(yōu)點(diǎn):1. 防止浮色發(fā)花問題；2. 提高光澤和鮮艷度；3. 提高顏料著色力；EFKA-4406 擁有與樹脂很好的相溶性, 從低極性至高極性,也包括硝基系統(tǒng).必須注意的是, EFKA–4406 若用在氯化聚合物, 能導(dǎo)致膠凝和黃變. 若用在無溶劑環(huán)氧系統(tǒng)里, 能導(dǎo)致黃變. EFKA–4406 是特為硝基和丙烯酸樹脂開發(fā)的.
