In the competitive world of synthetic leather manufacturing, achieving efficient release from casting papers while maximizing their lifespan is paramount for both quality and cost-effectiveness. IOTA 2107 addresses this critical need as a premium, high-purity silicone-based stripping agent engineered to deliver exceptional performance in PU and PVC leather production.

Core Composition & Quality:
IOTA 2107 is distinguished by its primary active ingredient: silicone. Rigorous quality control ensures a purity level exceeding 99.8%. This exceptional purity is fundamental to its performance, guaranteeing consistency, reliability, and minimizing the risk of unwanted side reactions or contamination within sensitive leather coating formulations. The absence of significant impurities translates directly to predictable results on the production line.

Primary Function: Superior Stripping Performance
The fundamental role of IOTA 2107 is to facilitate the clean and efficient separation of the cured synthetic leather film (whether PU or PVC-based) from the release paper or belt used during the casting process. Its advanced silicone chemistry creates an optimal, low-energy interface between the release surface and the leather coating. This action is crucial for:

1. Excellent Stripping Effect: Ensures the synthetic leather releases smoothly and completely without tearing, sticking, or leaving residues on the paper. This results in flawless leather surfaces ready for finishing.

2. Minimized Scratch Damage: By promoting effortless release, IOTA 2107 significantly reduces mechanical abrasion and scratching on the expensive release paper during the peeling process. This protective effect is a major contributor to cost savings.

3. Increased Release Paper Reusability: Protecting the release paper from scratches and wear directly extends its operational lifespan. Manufacturers can achieve significantly more production cycles per release paper, leading to substantial reductions in consumable costs and downtime associated with paper changes.

Application & Usage: Streamlined Integration
IOTA 2107 is designed for straightforward incorporation into existing production processes:

1. Direct Addition: The agent is added directly into the PU leather coating solution (e.g., PU resin mixture) or the PVC surface paste during the compounding stage.

2. Thorough Mixing: After addition, the formulation must be stirred adequately and homogenized completely. This ensures the uniform dispersion of the silicone stripping agent throughout the coating, guaranteeing consistent release performance across the entire leather surface.

3. Standard Coating: The mixture is then applied onto the release paper or belt using conventional coating techniques (knife coating, reverse roll, etc.) and processed through the standard curing/drying ovens.

Target Applications:
IOTA 2107 is specifically formulated for use in the production of:

• Polyurethane (PU) Synthetic Leather: Including wet-PU and dry-PU processes for various applications like apparel, footwear, upholstery, and automotive interiors.

• Polyvinyl Chloride (PVC) Artificial Leather: Used in applications ranging from upholstery and automotive to bags and coverings.

Optimal Dosage:
The recommended dosage range is 0.2% to 0.7%, based on the total weight of the coating formulation (PU resin solution or PVC paste). The precise dosage within this range depends on several factors:

• Specific Formulation: The type and composition of the base resins, solvents, fillers, and other additives.

• Release Paper Type: The characteristics and coating of the release paper being used.

• Desired Release Force: The specific ease of release required for the process and final product.

• Process Conditions: Factors like curing temperature and line speed. Pilot trials are recommended to determine the ideal dosage for each unique application.

Key Competitive Advantages:

• Unmatched Stripping Efficiency: Ensures clean, consistent, and trouble-free release of synthetic leather from casting papers/belts.

• Superior Release Paper Protection: Dramatically reduces scratching and surface wear, maximizing the number of production cycles achievable per paper.

• Significant Cost Reduction: Lower paper consumption directly decreases a major operational expense.

• Enhanced Production Efficiency: Minimizes downtime caused by paper changes and issues related to poor release (tearing, sticking).

• High Purity & Reliability: >99.8% purity guarantees consistent performance and formulation stability.

• Ease of Use: Simple direct addition and mixing integrate seamlessly into standard production workflows.

Conclusion:
IOTA 2107 stripping agent represents a sophisticated solution for synthetic leather manufacturers seeking to optimize their release process. Its high-purity silicone formulation delivers outstanding stripping performance, critically protects valuable release papers, and substantially increases their reuse potential. By integrating IOTA 2107 into PU or PVC coating formulations within the 0.2-0.7% dosage range, producers achieve superior product quality, enhanced operational efficiency, and significant cost savings through reduced consumable expenses and minimized downtime. It is an essential additive for modern, competitive synthetic leather production.
