NPEL-127 is an undiluted, low-viscosity bisphenol-A liquid epoxy resin. It offers viscosity lower than NPEL-128 while delivering similar performance. After curing with polyamine or polyamide hardeners, it provides excellent mechanical strength, chemical resistance, and thermal stability. With its low hydrolyzable chlorine content, it is particularly suitable for applications in the electronics industry.

Chemical Composition:
Bisphenol A-type glycidyl ether resin

Basic Resin Properties:

Item	Property	Unit	Specification
1	Appearance	—	Liquid
2	Epoxy Equivalent	g/eq	176–184
3	Color	Gardner	0.0–1.0
4	Hydrolyzable Chloride	ppm	300–800
5	Viscosity	cps @ 25℃	8,000–11,000

Viscosity-Temperature Curve:
Please refer to datasheet for the viscosity vs. temperature profile.

Applications:
Encapsulation materials, laminated boards, civil flooring, mold applications, adhesives, and coatings.

Shelf Life:
12 months at room temperature under sealed conditions. If slight cloudiness or crystallization occurs, heating to 50–60℃ with stirring will restore the original state.

Safety Precautions:
The resin may cause skin or eye irritation. In case of skin contact, wash immediately with water and soap. In case of eye contact, rinse thoroughly with plenty of water for 15 minutes and seek medical attention.
