Epoxid hardener G-91

Imidazole adduct for the curing of epoxy powder coatings; excellent chemical resistance, mechanical properties and capability for low temperature cure. High gloss epoxy powder coatings based on this hardener can be cured at temperatures ranging from 200°C to 110°C. Suitable for various substrates (composites, MDF); physical film properties are not affected by cure temperature; a prime choice for use with Estron’s matting agent Epomatt G-152 to create matte, interior-grade powders that can cure as low as 125°C. Recommended dosage = 3–6 parts Epoxy Hardener G-91 per 100 parts epoxy resin.
