Zeology ≠ zeolite

The demand for chrome free and GDA (glutardialdehyde) free leather is bigger than ever. And Zeology – a patented modified zeolite chemistry – delivers just that. Proven superior leather and environmental performance. Ensure that you, as a brand or tannery, are working with ‘the real thing’ and not just any zeolite based tanning agent. Are you in doubt? Nera will always provide professional technical support.

Zeology ≠ zeolite. 4 reasons why:

1. Leather performance.

Zeolite as a unmodified raw material, sold by the kilogram, is not a suitable tanning agent. The only perceived advantage of these zeolite blends is the price per kilogram of the tanning agent. Conversely Zeology, with a modified zeolite (patented), is developed for optimal leather performance on any substrate with low environmental impact and unmatched production consistency.

2. Certifications

Zeology is the only zeolite-based tanning agent with ZDHC MRSL Conformance (Level 3), C2C Certified Material Health CertificateTM at the Platinum level and a ToxFMD Screened Chemistry certification.
