PENGARUH SENYAWA SILAN TERHADAP SIFAT MEKANIK MATERIAL PELAPIS PADUAN HIBRID EPOKSI TERMODIFIKASI POLIURETAN
Abstract: Preparation of
hybrid coating material from modified epoxy polyurethane (ETP) and silan (Si)
has been done. Epoxy and polyurethane were modified with silan using
γ-Glisidoksil propil trimetoksisilan (GPTMS) and γ-aminopropyl
triethoxysilane (γ-APS) and also dibutyltindilaurate (DBTL) as catalyst.
Fourier Transform Infrared (FTIR) characterization indicated that the hybrid
coating material has been formed. The results of the analysis of NCO percent
and conversion rate of isocyanates (α) also verified that the ETP-Si hybrid
coatings have been formed. The addition 30% of silane as Si-O group indicated
the rest of NCO percent was the lowest for hybrid coating material with
polyurethane concentration of 5% and 10. The composition of ETP5% - Si 30% was
the optimum composition from the ETP-Si hybrid coating material based on the
mechanical analysis.
