Huihong Solvent-Based Dispersants: HNP 1200, HNP 1108 and HNP 1800

Huihong offers three solvent-based dispersants for different formulation needs: HNP 1200, HNP 1108 and HNP 1800. Their recommended uses cover organic pigments, carbon black, coating mill bases and low-polarity systems. In addition, all three grades have a listed active content of 100%.

Each grade has a distinct application focus. HNP 1200 targets pigment dispersions in NC inks and industrial coatings. Meanwhile, HNP 1108 provides wetting and dispersing functions for several coating applications.

HNP 1200 for Organic Pigments and Carbon Black

HNP 1200 is a solvent-based dispersant for organic pigment and carbon black dispersions. Its recommended applications include nitrocellulose (NC) inks and industrial coatings.

For formulators working with these pigments, HNP 1200 offers a grade to evaluate within the specified application areas. Its listed active content is 100%.

When discussing this grade with Huihong, identify the pigment type and intended ink or coating system. This information provides a clear starting point for product selection and technical discussions.

HNP 1108 for Wetting and Dispersing

HNP 1108 is a solvent-based wetting and dispersing agent for mill bases and coating formulations. Its application range includes:

• Industrial coatings
• Wood coatings
• Floor coatings
• Mill bases

In addition, Huihong recommends HNP 1108 for economical solvent-based systems and alkyd resin applications. Therefore, it is a relevant option to discuss when these systems form part of your product range.

Like the other two grades, HNP 1108 has a listed active content of 100%. However, its application guidance places particular emphasis on both wetting and dispersing.

HNP 1800 for Low-Polarity Systems

HNP 1800 is a solvent-based dispersant for low-polarity systems. It also has a listed active content of 100%.

Unlike the application descriptions for HNP 1200 and HNP 1108, the supplied information defines HNP 1800 primarily by system polarity. Accordingly, formulators can use this distinction when preparing an initial shortlist.

For further evaluation, share your resin and solvent system with Huihong. Then request the technical information needed to assess the grade in your formulation.

Solvent-Based Dispersants: Grade Comparison

The following table summarizes the supplied product information.

Grade	Product Focus	Recommended Applications	Active Content
HNP 1200	Dispersant for organic pigments and carbon black	NC inks and industrial coatings	100%
HNP 1108	Wetting and dispersing agent	Mill bases, industrial coatings, wood coatings and floor coatings; recommended for economical solvent-based systems and alkyd resin applications	100%
HNP 1800	Dispersant for low-polarity systems	Low-polarity solvent-based formulations	100%

Although these grades share the same listed active content, their recommended uses differ. Therefore, the application description provides a more useful selection guide than active content alone.

Choosing a Grade for Your Formulation

Start with the application details when comparing these solvent-based dispersants.

For organic pigments or carbon black in NC inks and industrial coatings, consider HNP 1200 for evaluation. For coating mill bases or alkyd applications that require a wetting and dispersing agent, review HNP 1108. Alternatively, if your formulation uses a low-polarity system, discuss HNP 1800 with the technical team.

Before starting trials, prepare the following information:

• Resin type and solvent blend
• Pigment type, where applicable
• Intended coating or ink application
• Current formulation requirements
• Processing conditions

Next, request grade-specific guidance on dosage and incorporation. The supplied product summary does not specify these details, so it does not establish a universal addition level for the three grades.

Discuss Your Dispersant Requirements with Huihong

HNP 1200, HNP 1108 and HNP 1800 provide different starting points for solvent-based formulation development. Together, they cover the application areas outlined above, from pigment dispersions to low-polarity systems.
