Syntheses And Characterısatıon Of Sılıcone Modıfıed Acrylıc Resıns
In this study new silicone modified acrylic resins, which could be employed in surface coatings, were prepared. Firstly, macromer (MK) was prepared from 2-HEMA and reactive siloxane prepolymer (Z-6018), which has hydroxil groups at repeated units. Then, copolymerization of the MK and various acrylic monomers (ethylacrylate and methylmethacrylate) were attempted in the presence of toluene. The structure and thermal properties of the copolymers were determined with Fourier Transform Infrared Spektroscopy (FTIR), Differential Scanning Calorimetry (DSC) and thermogravimetric analyses (TGA). And also the usage of products were investigated as surface coating materials. The hardness, drying time, gloss, adhesion, water resistance and alkaline resistances tests were applied to the films and the results were compared. It was observed that the prepared films had high hardness degree, %100 adhesive, fast drying time, good water and alkaline resistances. As a result, the new silicon acrylic copolymers that prepared in this study can be used as surface coating materials.
