Abstract

Önemli
kaplama teknolojilerinden biri olan ultraviyole (UV) ışıkla sertleştirme
yöntemi, artan uygulama alanları ve diğer yöntemlere kıyasla var olan
avantajları ile birlikte her geçen gün daha fazla tercih edilmektedir. Bu
makalede, bir izosiyanat akrilat olan ICA (Laromer® LR 9000) reçinesi ile
monoetilen glikol (MEG), dietilen glikol (DEG) ve dialkol ile sonlandırılmış
perfloropolieter türevi olan floro alkol (Fluorolink® E10-H) içeren reçine
sistemleri kullanılarak kaplamalar hazırlanmıştır. Bu reçine sistemlerinin ısı
ve UV ile sertleştirilmesi sonucunda farklı oranlarda flor içeren serbest
filmler elde edilmiş ve ayrıca alüminyum levhalar üzerine de bu formülasyonlar
kaplama yapılmıştır. Elde edilen serbest filmlerin; çekme testi, termogravimetrik
analiz (TGA) ve diferansiyel taramalı kalorimetre (DSC) yardımıyla mekanik ve
termal özellikleri belirlenmiştir. Ayrıca alüminyum levha üzerine yapılan
kaplamaların özellikleri ise; kalem sertlik testi, çapraz kesme testi,
parlaklık testi ve temas açısı testi ile gözlemlenmiştir. Sonuçlar
incelendiğinde hidrofobik ve parlak bir kaplama elde edildiği görülmüştür.
Ayrıca farklı oranlarda eklenen floro alkolün monoetilen glikol içeren yapı ile
dietilen glikol içeren yapının mekanik özelliklerinde farklı etkiler yarattığı
tespit edilmiştir.

Investigation of Mechanical, Surface and Thermal Properties of Dual-Curable Hydrophobic Coatings

Abstract

One of the important
coating technologies, ultraviolet (UV) light curing, is increasingly preferred
with increasing application areas and advantages that are present compared to
other methods. In this article, coatings were prepared
using ICA (Laromer® LR 9000) resin, an isocyanate acrylate resin, and resin
systems containing monoethylene glycol (MEG), diethylene glycol (DEG) and
fluoro alcohol (Fluorolink® E10-H), a perfluoropolyether derivative terminated
with dialkol. As a result of
heat and UV curing of these resin systems, free films were obtained at
different ratios fluorine containing and these formulations were also coated on
aluminum sheets. Obtained free films;
Mechanical and thermal properties were determined by tensile testing,
thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC).
Furthermore, the properties of the coatings coated on the aluminum sheet
determined by tests as pencil hardness test, cross-cut test, gloss test and
contact angle test. When the results are
examined, it is seen that a hydrophobic and bright coating is obtained.
It
has also been found that fluoroalcohol added at different ratios has different
effects on the mechanical properties of the structure containing diethylene
glycol with the structure containing monoethylene glycol.
