DOTP Plasticizer Enhances Thermoset Ink Stability in Peru

Henan GO Biotech Co., Ltd. provides plasticizer solutions for PVC and flexible polymer applications. This project addressed the formulation requirements of a Peruvian customer producing thermoset inks, using DOTP, a non-phthalate plasticizer, to optimize flow, leveling, flexibility, and stability for textile printing and advertising printing applications.

Project Background and Challenges

The customer is a Peruvian manufacturer of thermoset inks. As the market places greater emphasis on print consistency and environmentally friendly materials, the customer sought to develop more eco-friendly thermoset inks while maintaining its existing production pace as much as possible.

Printed Surface Performance:More stable flow and leveling performance required.
Formulation Processing Stability:Focus on the impact of plasticizer volatility on processing and application consistency.
Material Upgrade Direction:Seeking a non-phthalate plasticizer replacement pathway.

Solution: Application Analysis and Validation for Ink Formulations

Application Analysis Analyzed the flow, flexibility, and stability requirements of PVC-based plastisol inks.
Product Recommendations Recommended DOTP as a candidate solution combining compatibility with low-volatility characteristics.
Recipe Optimization Supported the plasticizer system upgrade with minimal process adjustments.
Performance validation Focused on processing performance, leveling support, flexibility, and storage stability.

Project Outcomes and Phase Value

After introducing DOTP, the customer gained a non-phthalate plasticizer option better suited to plastisol ink applications. The solution helps improve formulation flow and leveling, flexibility, and processing consistency, while its low-volatility characteristics support stable performance during storage, transportation, and repeated production. It also provides a practical formulation upgrade path for the customer’s transition toward more environmentally responsible ink materials.
