　　Applications

　　Irganox 1076 is used in polyolefins such as polyethylene, polypropylene, polybutene, as well as, in other polymers, such as engineering plastics, styrene homo- and co-polymers, polyurethanes, elastomers, adhesives, and other organic substrates.

　　It can be used in combination with other additives such as co-stabilizers (thioethers, phosphites, phosphonites), light stabilizers, and other functional stabilizers.

　　Irganox 1076 is recommended for applications such as:

　　• Hot-melt adhesives

　　• Solvent-based coating applications

　　• Tackifier resins

　　Recommended Concentrations

　　The amount of Irganox 1076 required for optimum performance should be determined in trials covering a concentration range. Concentrations up to several percent may be used depending on the substrate, processing conditions, requirements of the end application, and long term thermal stability requirements. 0.05% – 0.2% of Irganox 1076 provides long term thermal stability to the polymer.

　　Application Concentration

　　Polyolefins 0.1 – 0.4%

　　Styrene homo- and co-polymers 0.1 – 0.3%

　　Hot melt adhesives 0.2 – 1%

　　Synthetic tackifiers resins 0.1 – 0.5%

　　Solvent-based coatings 0.2 – 1.0%

　　Safety

　　General The usual safety precautions when handling chemicals must be observed. These include the measures described in Federal, State, and Local health and safety regulations, thorough ventilation of the workplace, good skin care, and wearing of protective goggles.

　　Storage

　　Properly stored and protected, an unopened container of Irganox® 1076 should have a shelf life of at least one year.
