Other: 3D printing photopolymer resins, mold manufacturing, etc.
V. Curing Recommendations:
NPEF-170 is compatible with various curing agents. Recommended curing systems:
Amines (e.g., TETA, DETA): Room-temperature or medium-temperature curing, suitable for adhesives and coatings.
Anhydride curing agents (e.g., MHHPA, MeTHPA): High-temperature curing (120-150°C), suitable for electronic packaging and high-performance composites.
Modified amines/polyether amines: Enhance toughness and impact resistance.
Latent curing agents (e.g., dicyandiamide): Suitable for single-component storage systems.
Typical Curing Conditions (using amine curing agents as an example):
Mixing Ratio: Resin : Curing Agent = 100 : 20–30 (by weight; refer to specific curing agent data)
Curing temperature: 25°C (24h) or 80°C (2-4h)
Post-curing (optional): 100-120°C (1-2h) to enhance performance
VI. Product Packaging:
225KG/drum. Store sealed in a cool, dry place away from direct sunlight. Recommended storage temperature: 10-30°C.
