Compounds, Dispersions and Emulsions
What are Compounds?
Waxes which have been melted into a liquid media and later recrystallized under controlled temperature conditions.
Wax performance can be defined by their chemical structure and molecular weight.
Waxes are melted in a variety of media such as Linseed Oil, Soya Alkyd Oils, Mineral Oil or varnishes such as Alkyds or hydrocarbons. This combination allows for print applications to achieve a high quality finish while improving processing conditions by ease of incorporation.
|Rub Resistance||The ability to withstand the effects of repeated rubbing and scuffing, and to preserve print integrity and quality.|
|Slip / Non-skid||Control the Coefficient of Friction of surfaces|
|Block Resistance||Blocking is the undesirable sticking together of two printed surfaces when pressed together or placed in contact with each other for an extended period of time.|
|Off-setting||Transfer of Ink from one sheet to another|
|Over-Printability||Ease of printing of layers|
Oil or varnish adds gloss, hardness, and lubricity to ink formulations. Waxes add mar, scuff, and rub resistance, slip, and anti-blocking. We have found that melting and compounding the two into a paste provides a synergy that significantly improves these properties.
