  Q5. Why choose JH 1051 for grouts or laminates?

A5. Its medium viscosity makes it easier to mix with fillers or fabric, and its good open time and strength ensure proper wetting and adhesion.

Q6. Can it be used in humid or marine environments?

A6. Yes. Like other polyamide curing agents, JH 1051 offers excellent corrosion resistance and moisture tolerance, making it suitable for primers and coatings in marine or coastal areas.

Q7. What is the suggested mix ratio with epoxy resin?

A7. For epoxy resins with EEW ~190, the recommended usage is approximately 55–65 parts hardener per 100 parts resin by weight. Perform a lab test to fine-tune the ratio for your specific application.

Q8. Does it cause blushing?

A8. JH 1051 has low blushing tendency but is not a fully blush-resistant system like JH 1001 or JH 1010. It performs well under most ambient conditions.

Q9. Can I pigment or fill it?

A9. Yes. You can mix it with pigments and fine fillers (like silica flour, talc, or colored oxides) to make grouts or pigmented coatings. Always test compatibility before use.

Q10. What is the shelf life of JH 1051?

A10. Shelf life is 12 months when stored in a cool, dry place in sealed containers away from direct sunlight and moisture.
