Nazdar Sipi440 Ts-100 Flattening Powder

SIPI440 Additive for Inks

Benefits and Uses:

1. Gloss Reduction:

   • Efficient Flattening: SIPI440 is highly effective in reducing the gloss level of inks, achieving a matte finish with less additive compared to alternatives like SIPI414.

2. Block Resistance:

   • Improved Block Resistance: The additive enhances the ink's ability to resist blocking, preventing the printed materials from sticking together when stacked or rolled.

3. Viscosity Increase:

   • Thicker Ink: SIPI440 increases the viscosity of the ink, making it thicker and more controllable during application. This is particularly beneficial for printing processes that require precise ink placement and reduced ink spread.

Cautions:

1. Curing Issues:

   • Potential Curing Problems: Excessive use of SIPI440 can interfere with the curing process of the ink, potentially affecting the final durability and adhesion of the printed material.

2. Reduced Ink Flow and Transfer:

   • Flow and Transfer Reduction: Too much SIPI440 can reduce the ink's flow and transfer properties, making it harder to achieve smooth and consistent prints.

3. Handling and Mixing:

   • Difficult Handling: The additive powder is very light and can be challenging to mix into the ink uniformly. Proper handling and mixing techniques are required to ensure consistent results.

4. Outdoor Durability:

   • Decreased Durability: Flattening inks with SIPI440 may reduce their outdoor durability, potentially leading to faster degradation when exposed to environmental elements.

Usage Instructions:

1. Proper Dispersion:

   • Mixing Requirement: To ensure proper dispersion of SIPI440 in the ink, a mixer should be used. This helps achieve a uniform consistency and effective performance of the additive.

2. Maximum Amount:

   • Additive Proportion: SIPI440 should be added to the ink in amounts up to 5% by weight. Exceeding this limit can lead to the cautions mentioned earlier.
