Pre-Mixed Solvent for Printing on PVC Film

PVC ink solvent helps optimize print quality, shortens processing time, and improves production efficiency. With a specialized formula researched by K-Chem, the pre-mixed solvent for printing on PVC film not only strongly corresponds with solvent-based inks but also delivers exceptional performance on PVC film. This solvent enables even ink dispersion, strong adhesion, and fast drying while maintaining sharpness, preventing smudging, and avoiding deformation of the printed film.

What is PVC Ink Solvent?

PVC ink solvent is a pre-formulated liquid chemical used to adjust viscosity, enhance adhesion, and improve print quality of inks on PVC film surfaces. It helps the ink become uniform, easy to print, and ensures sharp, long-lasting prints on PVC materials.

Outstanding Features of K-Chem’s Pre-Mixed Solvent for Printing on PVC Film

K-Chem’s pre-mixed solvent for printing on PVC film is developed with a specialized formula to achieve optimal performance in every stage of application, offering the following advantages:

Efficient Solubility

K-Chem’s solvent rapidly and effectively dissolves key ink components such as pigments, polymer resins, and additives, producing a uniform ink mixture and preventing sedimentation, separation, or clumping.

Optimized Evaporation Rate

The evaporation rate of K-Chem’s PVC ink solvent is fast enough to produce high-quality prints and avoids issues such as ink smudging or blocking (ink transfer onto the back) during product winding.

High Adhesion Ability

Due to the glossy and inert nature of PVC surfaces, ink adhesion is often challenging. K-Chem’s pre-mixed solvent effectively addresses this issue by creating optimal conditions for the ink resin to bond to the film. As a result, the final product does not peel or fade, making it ideal for high-durability applications such as labels, decals, and plastic tube printing.

Safe and Environmentally Friendly

K-Chem’s PVC ink solvent formula prioritizes low-toxicity, low-odor components that minimize respiratory impacts for users. Additionally, its controlled evaporation helps reduce VOC emissions, supporting compliance with occupational safety and environmental regulations.

Common Ingredients in K-Chem’s Pre-Mixed Solvent for Printing on PVC Film

For Gravure Printing Technology: Organic solvents such as Toluene (with or without), EA, IPA, DMC, etc., in optimal ratios to ensure good ink adhesion and clear image display on PVC film.

For Flexo Printing Technology (Solvent-Based): Organic solvents like NPAC, NPA, Ethanol, etc., in optimized ratios to ensure strong ink adhesion and sharp image display on PVC film while avoiding damage to the Anilox roller and printing plates.

Instructions for Using K-Chem’s PVC Film Ink Solvent

Review Instructions and Technical Information

Before starting, carefully read the mixing ratio instructions for K-Chem’s PVC film ink solvent (typically 15–25% solvent relative to the ink volume). Following the correct ratio helps control viscosity, adhesion, and drying time of the ink when printing on PVC film.

Accurate Measurement

Use measuring devices or graduated cups to precisely measure the required amounts of ink and K-Chem’s PVC film ink solvent. Avoid estimating by eye, as incorrect viscosity can affect print quality or lead to material waste.

Proper Mixing Technique

Slowly add the solvent into the ink while stirring thoroughly with a stirrer or a specialized mixing machine to achieve uniform viscosity. After mixing, use a viscosity cup (such as a Zahn cup or Ford cup) to recheck the viscosity.

Test Print on PVC Sample

Before mass production, perform a test print on a PVC sample to check ink adhesion, drying speed, color, and sharpness. This ensures the print is crisp, without smudging or streaking.

Clean Equipment After Use

After printing, clean tools and printing equipment with a specialized cleaning solvent to avoid ink residue buildup. This helps extend the lifespan of the machinery and maintains consistent print quality.

Storage Guidelines for K-Chem’s Pre-Mixed PVC Film Ink Solvent

Store in a Dry, Cool Place

• Keep the solvent in a dry, cool place, below 30°C, and away from humidity.
• Avoid direct sunlight and heat sources such as stoves or heat-generating machinery, as these may cause rapid evaporation or alter the solvent’s chemical composition.

Seal Tightly to Prevent Evaporation

• After each use, tightly seal the container or drum of the pre-mixed PVC film ink solvent to minimize air exposure or contamination.

Keep Away from Fire Sources

• As the solvent is flammable, avoid open flames, cigarette butts, or heat sources. Place warning signs in the storage area.

Use Protective Gear

• Work in a well-ventilated area or use local exhaust systems to reduce solvent vapor concentration in the air.
• Wear gloves, masks, and protective goggles to avoid direct skin contact.

Check Expiry Date

• Before use, check the expiry date on the packaging. Expired solvent may lose its stability, affecting ink solubility, viscosity, or drying time.

Ensure Child Safety

• Store the solvent in a dedicated chemical storage area, placed high and out of children’s reach. Avoid direct contact with skin and eyes.
