Abstract
Resin epoksi merupakan material termoset yang banyak
digunakan sebagai perekat, coating, dan matriks dalam komposit
berbasis polimer. Epoksi memiliki sifat yang baik dalam hal
kekuatan tarik, kekuatan bending dan stabilitas thermal. Salah
satu aplikasi epoksi adalah sebagai bahan adhesif atau perekat..
Umumnya, perekat epoksi ditambahkan dengan hardener maupun
bahan aditif agar mampu curing pada temperatur kamar. Pada
penelitian ini dilakukan pembuatan bahan adhesif berbasis
polimer termoset yaitu epoksi. Epoksi yang dipakai adalah jenis
Diglycidyl ether of bisphenol A dengan amoniak dan asam asetat
sebagai curing agent, dengan perbandingan 10/20 ; 13,4/26,6 ;
16,7/33,3 ; 20/40. Lalu, bahan adhesif ini diaplikasikan ke baja
ASTM A-36. Hasil pengujian TGA menunjukkan dengan
penambahan amoniak dan asam asetat menurunkan stabilitas
thermal. Pengujian FTIR menunjukkan adanya ikatan kimia
antara epoksi, amoniak dan asam asetat. Hasil pengujian tarik
dan pengujian adhesif optimum pada penambahan 30% curing
agent amoniak dan asam asetat 5,30 Mpa dan 1,15 Mpa.

Epoxy resin is a thermoset material that is widely used as
adhesives, coatings, and polymer-based matrix composites.
Epoxy has good properties in terms of tensile strength, bending
strength and thermal stability. One application is as an epoxy
adhesive or adhesive. Generally, epoxy adhesive formulation
added with hardener and additives to be able to curing at room
temperature. In this research, the process of making adhesive is
an epoxy based thermoset polymer. Type of epoxy used was
diglycidyl ether of bisphenol A with ammonia and acetic acid as
curing agent, the ratio of ammonia and acetic acid is10/20 ;
13,4/26,6 ; 16,7/33,3 ; 20/40% by total weight. Furthermore, the
adhesive will be applied to the ASTM A-36 steel. The result from
TGA test is, more ammonia and acetic acid can reduce the
thermal stability. And FTIR test shows chemical bond between
epoxy, ammonia and acetic acid. The result from tensile test and
adhesive test shows the optimum result is from 30% curing agent
ratio which is 5,30 MPa 1,15 Mpa.
