How to Compare Crosslinker Prices When Active Contents Differ

How to Make a Fair Crosslinker Cost Comparison

Crosslinker quotations with different active contents should not be compared by product price alone. Convert each quotation to the cost of an equivalent quantity of active material, then review dosage, formulation performance, and application suitability. Before starting, ask every supplier to provide the active-content percentage, quotation basis, and price. The available product information does not include crosslinker prices or active-content values, so a numerical comparison requires additional supplier data.

Key Information to Collect

• Request the price per kilogram of supplied product and confirm whether the quotation includes packaging, delivery, or other charges.
• Obtain the supplier's active-content figure and the method or basis used to determine it.
• Convert all quotations to the same active-material basis before ranking them.
• Compare the dosage needed to achieve the required coating performance, rather than focusing only on the price per kilogram.
• Evaluate technical support, formulation references, substrate compatibility, and delivery conditions alongside material cost.

Active-Content Normalization Method

When a crosslinker is quoted by the kilogram of supplied product, divide the product price by the active-content fraction. A percentage must first be converted into a decimal. For example, a product containing 60% active material has an active-content fraction of 0.60. Dividing its price per kilogram by 0.60 gives the cost per kilogram of active material.

This calculation creates a more consistent basis for comparing products with different concentrations. However, it is only valid when suppliers define active content in a comparable way and the products perform the same function in the formulation. Solvent type, reactive groups, equivalent weight, and other technical differences may also affect the final cost.

Compare Formulation Cost, Not Just Raw-Material Price

The lowest normalized price may not produce the lowest coating cost. The required use level and performance target must also be considered. For a two-component water-based coating, calculate the amount of crosslinker required to reach the desired hardness, wear resistance, adhesion, water resistance, and chemical resistance. The practical comparison is therefore the cost of a complete formulation at the required performance level.

HPUA-7613 is described as an aliphatic hydroxy acrylic modified polyurethane dispersion for water-based two-component coatings. It is presented as a binder with high hardness, wear resistance, plastic-substrate adhesion, water resistance, and chemical resistance. The product is recommended for use with OS-9016 or OS-9018 hardeners. These details describe product compatibility and performance; they do not provide the active content or pricing of the hardeners.

Frequently Asked Questions

What is the formula for comparing crosslinkers with different active contents?

Divide the quoted price per kilogram of product by the active-content fraction. For accurate results, confirm that each supplier uses the same definition and measurement basis for active content.

Should I always choose the crosslinker with the lowest normalized price?

No. Include the required dosage, achieved performance, compatibility with the binder and substrate, processing conditions, technical support, and total delivered cost in the evaluation.

Do the available HPUA-7613 details include crosslinker prices?

No. The information identifies OS-9016 and OS-9018 as suitable hardeners for HPUA-7613, but it does not state their prices, active contents, or recommended dosage levels.

Conclusion and Next Steps

Ask suppliers for comparable quotations that clearly state product price, active content, quotation terms, and the basis used to determine active material. Normalize each price, then calculate the formulation cost at the dosage required for the target performance. Guanzhi reports an R&D, manufacturing, and direct-sales model, a minimum order quantity of 900 kg, and a stated delivery period of 7–10 days.
