Epoxy and epoxy novolac adhesive binders for structural reinforcement

This paper investigated the modification of epoxy no-bake adhesive binders to provide a higher thermal resistance and mechanical strength. The influence of epoxy novolac resins on the processing and physical mechanical properties of adhesives, thermal resistance is studied. It is found that the substitution of 20-40 % of epoxy resin for epoxy

synthesis and characterization of a low-molecular-weight novolac epoxy

Synthesis and Characterization of a Low-Molecular-Weight Novolac Epoxy

When compared to a commercial cresol novolac epoxy, the cured epoxidized coproduct resin shows comparable thermal and thermomechanical properties. When compared to a commercial BPA-based resin, the cured epoxidized coproduct resin shows improved mode 1 fracture values of 1.34 J m 1/2 ( K1C) and 448.16 J/m 2 ( G1C ).

Chemically-resistant epoxy novolac coatings: Effects of size

Furthermore, the thermomechanical performance of the new novolac coatings, i.e., unsieved-lignin EN (U-L EN) and sieved-lignin EN (S-L EN), are evaluated and compared with a DGEBF-based commercial coating, a lignin-based DGEBF coating (L-DGEBF), an epoxy novolac (EN) coating containing iron oxide pigment, and neat (i.e., particle-free) epoxy novolac and DGEBF coatings.

Preparation of low-CTE composite using new alkoxysilyl-functionalized

In order to prepare the epoxy material with high dimensional stability, alkoxysilyl-functionalized bisphenol A novolac epoxy was newly synthesized. The composite film of the new epoxy was prepared by adding polymer binder and its coefficient of thermal expansion (CTE) was measured.

Synthesis, characterization, and properties of novel novolac epoxy

In high-tech applications, however, epoxy resins with lower thermal expansion, higher toughness, better heat and moisture resistance were required. For this reason, modifications of epoxy resins, in both backbone and pendant groups have been continuously attempted in order to improve their thermal and physical properties [1], [2], [3].

what is epoxy resin - resin library

What is Epoxy Resin - Resin Library

In the context of composites, epoxy resin acts as the ¡®matrix¡¯ phase, whilst carbon fibre, aramid fibre and glass fibre act as the ¡®reinforcement¡¯ phase. Indeed, epoxy resin is a core matrix phase for a range of high-performance composites. Epoxies are highly compatible with powder-bound matting, kevlar, and woven roving matt.
