The HN-170 EcoPower Polyamino Acid Retarder is a cutting-edge solution designed for the construction industry, offering exceptional performance while prioritizing environmental sustainability. This product is part of a growing trend toward green chemistry, addressing the need for safer, more efficient materials in gypsum-based applications. Below, we explore its features, technical specifications, and the company behind this innovation.

Product Overview

Developed by Hebei Think-Do Chemicals Co., Ltd., the HN-170 EcoPower Retarder is a polymerized amino acid-based gypsum retarder. Its formulation combines advanced chemical engineering with eco-friendly principles, making it a preferred choice for manufacturers seeking to reduce environmental impact without compromising on quality. The product's biodegradability and non-toxic properties align with global sustainability goals, as highlighted by the National Institute of Standards and Technology (NIST), which emphasizes the importance of environmentally responsible materials in modern construction (NIST, 2025).

One of the standout features of the HN-170 is its ability to control the setting time of gypsum products with precision. This is critical in applications such as desulfurized gypsum, phosphogypsum, and other building materials where consistent performance is essential. The product's adaptability to various gypsum types and water hardness further enhances its versatility, making it a valuable addition to any construction material portfolio.

Key Features and Benefits

• Biodegradability: The HN-170 achieves 65% degradation within 28 days, ensuring minimal environmental impact. This aligns with NIST's guidelines on sustainable materials, which stress the importance of biodegradable alternatives to reduce long-term ecological harm (NIST, 2025).
• Non-Toxic and Safe: With an LD50 >2000 mg/kg and LC50 >2000 mg/L, the product is classified as non-toxic. Additionally, it is non-irritating to skin and eyes, as confirmed by mouse testing, making it a safe choice for workers and end-users.
• Stable Performance: The product exhibits excellent batch-to-batch and storage stability, ensuring consistent results across different production runs. This reliability is crucial for manufacturers who require predictable outcomes in their processes.
• Linear Dose-Effect Relationship: The retarding time is directly proportional to the dosage, allowing for precise control over setting times. This feature is particularly beneficial in complex construction projects where timing is critical.
• Excellent Fluidity: The powder's high fluidity ensures even mixing, reducing the risk of clumping and improving the overall quality of the final product. This is especially important in applications requiring uniformity, such as gypsum board production.
• Adaptability: The HN-170 works well with various gypsum types and additives, making it a flexible solution for different construction needs. Its compatibility with water of varying hardness further enhances its utility in diverse environments.
