溶剂型丙烯酸和 PU 近红外涂料的 ATO 分散体设计
A formulation and qualification framework for Antimony Tin Oxide (ATO) dispersions in solventborne acrylic and polyurethane coatings, covering solvent compatibility, letdown stability, cure, optical response, and durability.

快速解答
Qualify Antimony Tin Oxide (ATO) in the complete solvent, resin, and cure package. Stability in a carrier solvent alone does not show that the dispersion will survive acrylic letdown or a reactive polyurethane formulation.
Problem
ATO 濃縮物在樹脂調漆後可能會絮凝、增稠、產生種子或沉澱。在聚氨酯系統中,水分、催化劑、硬化劑和適用期的變化會增加相容性風險,而簡單的分散體檢查則不會出現這些風險。
作用機制
溶劑極性和蒸發曲線、分散劑吸附、樹脂親和力和水含量控制潤濕和顆粒相互作用。在固化膜中,聚集體尺寸、ATO 負載、黏合劑指數、膜厚度和固化狀態決定光譜衰減和任何所需的導電路徑。
Tradeoff
穩定 ATO 的溶劑混合物可能無法提供所需的樹脂溶解度、乾燥、固化、外觀或耐久性。提高 ATO 濃度會增強 NIR 衰減或電導率,同時增加霧度、色調、黏度、沉降和表面缺陷風險。
Material Strategy
Define the exact ATO grade and supplied form, solvent package, dispersant, resin, additives, and addition sequence. For polyurethane, include water control, mix ratio, catalyst, induction time, pot life, and cure conditions. If conductivity is outside the scope, compare the distinct absorber route using ATO vs Cs0.33WO3.
Recommended Architectures
- ATO 浓缩物转化为溶剂型丙烯酸:筛选溶剂冲击、树脂相容性、粘度漂移、干燥和附着力。
- 雙組分 PU 中的 ATO 分散體:將分散體製備與反應性調漆分開,然後驗證適用期和固化完整性。
- 底漆、活性層和保護性面漆:當一種配方無法滿足所有要求時,需要單獨的附著力、近紅外線控制和耐候功能。
Measurement & Validation
記錄溶劑成分、水含量、添加順序、流變學、粒度趨勢、沉降、過濾、適用期、乾燥和固化。比較匹配面板的光譜透射或反射、霧度、顏色、乾膜厚度、光澤或表面缺陷、附著力、耐化學性和耐候性。僅當指定電氣性能時才添加方塊電阻。
