使用特殊的有机硅助剂也可减少涂层上的灰尘堆积，提高清洁度。
BYK‑SILCLEAN 3700是溶剂型涂料体系的专用助剂。它是一种含羟基官能团有机硅改性的聚丙烯酸酯，由于其表面活性，它迁移到涂料表面。由于其含羟基基团，它在许多涂料配方都可以参入到聚合物的交联反应中（例如双组分聚氨酯、醇酸三聚氰胺、聚酯三聚氰胺、丙烯酸酯环氧、环氧苯酚）。通过这种方式，助剂永久地固定在涂层表面上，有机硅所贡献的表面性能也更持久，包括在户外暴露期间。
BYK‑SILCLEAN 3700使涂层表面同时具有疏水性和疏油性，从而减少了灰尘堆积和改善清洁度。耐水性增强可避免发白现象。
它还可以用来提高防涂鸦和胶带剥离性能。而且，BYK‑SILCLEAN 3700还改善了基材润湿、流平和表面滑爽。对于水性体系，也可通过使用BYK‑SILCLEAN 3720实现相同的性能。
