Storage & Handling
- Recommended Storage
- Store in a closed container and keep cool; otherwise ammonia gas comes out of solution and the material strength is reduced.tannerind.com
- Handling Precautions
- Use standard chemical PPE — splash goggles, gloves, lab coat. Refer to SDS for hazard-specific PPE requirements.Class-level guidance — not product-specific; the SDS controls.
- Incompatibilities
- copper, copper alloys, aluminum alloys, galvanized surfacestannerind.com
- Shelf Life
- Consult Technical Services for product-specific shelf life
For full hazard, PPE, and emergency response guidance, refer to the Safety Data Sheet (SDS) for this product. The SDS controls in all cases where guidance differs.
