Description
ANTIOX AHM-EC is a synergistic blend of various non-staining antioxidants, including primary phenolic stabilizers, thio-esters for the long term stability and phosphites for high temperature protection. The physical form of the components is primarily (but not completely) dusty in order to facilitate the dissolution / melting of the product.
Application
This formula has been designed to grant a wide spectrum protection either to hot-melt polymer systems or to polymer solutions. It can be used with adhesives, pressure sensitive adhesives, coatings, injection moulding or extrusion compounds.

Handling
For hot-melt adhesives, ANTIOX AHM-EC is very efficient at the following concentrations:
- Thermoplastic rubbers like SIS, SBS: 1.2-1.5% on rubber content;
- Ethylene-vinylacetate: 0.3-0.5% on EVA content;
- Thermoplastic polyurethanes: 0.2-0.4% on PU content;
- Polyamides: 0.5-1.0% on PA content.
For solventborne adhesives, ANTIOX AHM-EC is very efficient at the following concentrations:
- Natural rubber, SBR, chloroprene rubber, polyisoprene, butyl rubber: 0.25-0.5% on dry content.
ANTIOX AHM-EC can be added directly to the compound, either together with other recipe ingredients, or predispersed into one of them, or dissolved (for solvent solutions).
In hot-melt continuos system (by extrusion process) it is advisable that a liquid component (like liquid rosin esters or naphtenic oil, etc.) is used to give some tack to the surface of granules, in order to have a fair distribution over the total mass.
Packaging
The product is supplied in plastic bags (20 kg); fibre drums (50 kg).
Storing
Product must be stored in a dry place to avoid agglomeration.
Use within 24 months from production date (unopened and in the original packaging).
