How To Reduce Ink Viscosity

Under the general trend of water-based and environmental protection, the coating industry is developing in the direction of high solid and low viscosity, light curing, and water-based. Tianshi New Materials provides wax additives such as non-stratified micro-powder wax, anti-slip wax emulsion, and wear-resistant wax emulsion for water-based ink varnish. Tianshi has made technical reserves and production for water-based wax emulsions and water-based wax dispersions in the water-based field in advance. The future development direction will focus on environmentally friendly water-based additives and new materials, help China’s environmental protection market, contribute to the sustainable development of the industry, and create a better life.

1. Dry anti-sticking, adding 2%-6% can achieve a dry and non-stick surface effect. Excessive addition will affect the adhesion of the substrate. According to the use of the emulsion and the formula design, the addition amount generally does not exceed 8%.

2. This product mainly has a significant anti-surface adhesion effect, and a general anti-hot pressing effect. It can be used with silicone anti-sticking agents.
3. Anti-adhesive agent is also called water-based release agent. It has a separation effect when applied to plastic and packaging products such as OPP, PET, PVC, and PE glue.

4. It is used in water-based coatings, printing glue, waterproof coatings, water-based inks, water-based varnishes, acrylic emulsions, polyurethane emulsions, simulated flower and fruit water-based coating glue, paper anti-adhesion and waterproofing, water-based paints, leather edge oils, etc.

Polyethylene wax emulsion is the most commonly used wear-resistant additive in the ink industry. It also has the characteristics of improving hand feel, anti-adhesion, anti-sticking, and waterproofing. In water-based varnish, polyethylene wax mainly appears in four forms: water-based micro-powder wax, dispersion, micro-dispersion, and wax emulsion. Wax additives with different particle sizes have different performances in water-based inks. They should be selected or compounded according to different needs. The ethanol resistance of different wax additives is also very different. It should be noted during use. Water-based gravure ink manufacturers can also consider not using the wax additives commonly used in water-based flexographic plates. They can choose to cooperate with wax additive manufacturers to explore the most suitable additive specifications in the new system.

The purpose of using ink viscosity reducers is to reduce the viscosity of the ink while minimizing the impact on the ink’s body. Ink additives are new printing auxiliary materials used to prevent the printed product from “sticking dirty” during the paper collection process of offset lithography, replacing powder spraying.
