RHOPLEX® E-1691LF

• Excellent adhesion to vinyl
• Plasticizer migration resistance
• Excellent stain resistance (Flair pen, ballpoint pen, blood, ketchup, mustard, lipstick and coffee)
• Excellent alkali and solvent scrub resistance (typical household cleaners)
• Color stability
• Fast drying
• Low formaldehyde*

* - No formaldehyde or formaldehyde generating materials are intentionally added. Formaldehyde is not used in the manufacture, would not be expected to form during manufacture, and would not be expected to be present in the final composition unless at trace levels (≤ ppm) as an unknown impurity from the raw materials.

To achieve optimum properties, the polymer is typically formulated with wetting agents, coalescents for film formation, and rheology modifiers for printability. Standard RHOPLEX® E-1691 Emulsion contains low levels of formaldehyde (present in additives used in the polymerization of the emulsion). The additives, however, have been removed in the new version RHOPLEX® E-1691LF Emulsion—which has maximum formaldehyde level of 10 ppm.

Solvent Compatibility with RHOPLEX® E-1691 Emulsion

RHOPLEX® E-1691LF Emulsion is compatible with the typical alcohols and glycol ethers used in the graphic arts industry. We recommend formulating with a blend of coalescing agents to give optimum film formation:

• *50 parts Butyl CELLOSOLVETM Faster Evaporating Solvent
• *50 parts of DPnB (Dipropylene Glycol Monobutyl ether) Slower evaporating solvent
• Surfynol 104 BC surfactant supplied by and a trademark of Air Products, can be used with this blend to keep the solvents from separating

Compatibility with Other Polymers 

RHOPLEX® E-1691LF Emulsion is not readily compatible with standard styrene/acrylics used in the graphic arts industry. We recommend laboratory testing to check viscosity stability and general compatibility prior to producing larger scale batches.

Note: * - No formaldehyde or formaldehyde generating materials are intentionally added. Formaldehyde is not used in the manufacture, would not be expected to form during manufacture, and would not be expected to be present in the final composition unless at trace levels (≤ ppm) as an unknown impurity from the raw materials.
