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
