Apply less. Lose less.

Glaze Extend is a urease inhibitor coating designed to be directly applied to urea using batch or continuous flow blending and handling systems.
Glaze Extend contains the active ingredient N-(n-Butyl)thiophosphoric triamide (NBPT) which functions as an inhibitor of the enzyme urease. 
Urease pervasive in soil microorganisms converts urea into ammonia, which is susceptible to volatilisation if produced faster than it can be utilised by plants.
