Abstract

Blister disebabkan oleh osmosis, di mana air laut menyusup ke dalam laminasi struktur fiberglass komposit. Tujuan dari penelitian ini adalah untuk mencegah osmosis dalam struktur fiberglass dengan menambahkan coating hydrophobic dengan lima variasi rasio dari dua monomer, yaitu TMOMS (hydrophobic) dan PAM (salinity resistant). Kelayakan coating diketahui dengan melakukan beberapa pengujian, antara lain uji penyerapan air dengan variasi temperatur 15°C, 30°C, dan 40°C dengan monitoring 1 bulan, 2 bulan, dan 3 bulan, uji morfologi dengan SEM dan visual, serta analisis komposisi kimia dengan FTIR dan EDX, uji kekerasan, dan analisa termal dengan TGA/DSC. Hasil analisa dan pengujian menunjukkan penambahan rasio TMOMS, meningkatkan ketahanan termal dan sifat hydrophobic. Dari uji kekerasan menunjukkan bahwa perendaman fiberglass pada air laut dapat menurunkan kekerasan. Dari hasil keseluruhan pengujian, coating dapat bekerja mengurangi penyerapan air laut dan terbukti TMOMS dan PAM bercampur dengan baik. =========== Blister caused by osmosis, in which sea water seeping into the fiberglass composite laminate structure. The purpose of this study is to prevent osmosis in fiberglass structure by adding a hydrophobic coating with variation of ratios of the two monomers, namely TMOMS (hydrophobic) and PAM (salinity resistant). Feasibility of the coating are known by some testings, such as water absorption test with temperature variation 15°C, 30°C, and 40°C by 1 month , 2 months , and 3 months monitoring, morphology test by SEM and visual, as well as composition analysis chemistry with FTIR and EDX, hardness, and thermal analysis by TGA/DSC. Results of analysis and testing showed the addition of TMOMS ratio, increasing the thermal resistance and hydrophobic properties. Also determined that water absorption causes the hardness and stiffness of fiberglass decreased by hardness testing. From the overall results, the coating can reduce the absorption of seawater and proven TMOMS and PAM are well mixed
