The aim of this study is to investigate the effects of different clay-based additives, which are physically added to water-based paints used in the chemical industry, on the physical strength of paints. For this purpose, three different clay-based additives (kaolin, montmorillonite and sepiolite) were added in three different amounts (0.5-1-2%) to commercial waterborne paints (Ral 6034, Ral 7012, Ral 9003) supplied in three different colors for paint tests and the effects of these additives on some paint properties were studied. As a result of the tests, gloss, cross-cut adhesion class, colorimetry and FT-IR results comparable to those of commercial waterborne coatings without additives were obtained. The values closest to the test results of paints without additives were obtained with the combinations of "Ral 6034 + 1% kaolin", "Ral 7012 + 2% mmt" and "Ral 9003 + 0.5% kaolin". Without deteriorating the other properties of these paints, an increase of 11.1%, 55% and 3.9% was observed for the combinations of "Ral 6034 + 1% Kaolin", "Ral 7012 + 2% mmt" and "Ral 9003 + 0.5% Kaolin", respectively.

Bu çalýþmada amaç; kimya sektöründe kullanýlan su bazlý boyalara fiziksel olarak ilave edilen kil esaslý çeþitli kaktý maddelerinin, boyalarýn fiziksel dayanýmlarý üzerindeki etkilerinin incelenmesidir. Bu amaçla üç farklý renkte temin edilen ticari su bazlý boyaya (Ral 6034, Ral 7012, Ral 9003), üç farklý kil esaslý katký maddesi (kaolin, montmorillonit ve sepiyolit) üç farklý oranda (%0.5-1-2) ilave edilerek boya testleri gerçekleþtirilmiþ ve bu ilavelerin bazý boya özelliklerine etkisi incelenmiþtir. Yapýlan testler sonucunda, katkýsýz ticari su bazlý boyalara benzer parlaklýk, çapraz kesme yapýþma sýnýfý, renk ölçümü ve FT-IR sonuçlarý elde edilmiþtir. Katkýsýz boyalarýn test sonuçlarýna en yakýn deðerler; “Ral 6034 + %1 kaolin”, “Ral 7012 + %2 mmt” ve “Ral 9003 + %0.5 kaolin” kombinasyonlarýnda elde edilmiþtir. Bu boyalarýn diðer özellikleri bozulmadan, yapýþma mukavemetlerinde Ral 6034 + %1 kaolin, Ral 7012 + %2 mmt ve Ral 9003 + %0.5 kaolin kombinasyonlarý için sýrasýyla, %11.1, %55 ve % 3.9 artýþ gözlenmiþtir.
