Solvex Petrolatum

Solvex petrolatum is a stabilized form of petroleum grease that is particularly suitable as a tack reducing agent for all types of no heat paste inks. Unlike solvents and oils, Solvex petrolatum will not reduce viscosity rapidly when reducing tack. Solvex petrolatum can also be used in limited quantity in heatset inks as a tack stabilizing agent to keep blanket piling due to rapid solvent evaporation under control. For this purpose, no more than 3-5% is recommended as a maximum figure. Solvex petrolatum is particularly useful as an ingredient in inks that must stay "open" for extended periods of time. However, it is not recommended for use in rapid-setting sheetfed inks. See our product "GLO" for use in quickset formulations.

Solvex Pitch

Use Solvex PITCH as a wetting agent to increase flow in almost any type of carbon black-based paste ink. Solvex PITCH has approximately 10% VOC's, so it can be used in low-VOC formulations. Between 1 and 4% by total formula weight is the recommended dosage. Between 7 and 12% by weight of carbon black is what is recommended for black dispersions to induce freeflowing properties. Solvex pitch is particularly effective on 'high structure' carbon blacks commonly found in newsinks and business forms inks. Solvex PITCH is compatible with almost every type of paste ink resin, oil, and solvent available. However, Solvex PITCH is not recommended for use in VOC-free or in radiation-curable inks, as it contains some VOC's.

Solvex solvents

Solvex products are quickset and heatset solvents in severely hydrotreated, low-aromatic forms. Solvex products are available as a convenience item in limited quantity, because we are not petroleum distributors. Solvex 60 is a 60-type ink solvent: best suited for quickset formulations. Solvex 525 is a 52-type solvent: best suited for quickset and tack-stable heatset inks. Solvex products are great for setting tacks of quickset and heatset inks. Below are the specifications for Solvex products: (Sorry, no 3.5 gal kits for any liquid petroleum products!)

Tamalene 750

Tamalene 750 is a severely hydrotreated napthenic mineral oil in the 750 SUS viscosity range. Tamalene 750 is ideal for low-cost newsinks as a tack adjuster or vehicle component. It is excellent as a low-cost, ultralow-VOC alternative to soy oil. Tamalene 750 has a pale, straw color and features near-zero VOC content. The odor of Tamalene 750 is also quite low. Below are the specifications for Tamalene:

Product	Tamalene 750
Viscosity (Saybolt Universal Seconds @ 100 F)	750-800
Lbs/Gal (Specific Gravity)	7.65 (0.92)
Flash Point (deg F)	380
