Medical Grade Silicone Rubber Solvent-Free Eco-Friendly Mold Release Agent ISO

Product Specification

Solvent-Free Eco-Friendly Mold Release Agent for Medical Grade Silicone

Product Introduction

Lubekote LK-9800-MG represents the pinnacle of clean, biocompatible mold release technology for medical grade silicone rubber applications. As the medical device industry increasingly demands higher purity standards and comprehensive biocompatibility documentation, traditional solvent-based or silicone oil-containing release agents are no longer acceptable. LK-9800-MG is formulated with a proprietary solvent-free, water-based polymer system that eliminates all organic solvents, silicone oils, and potentially cytotoxic extractables. The product has been independently tested and validated against ISO 10993-5 (cytotoxicity) and ISO 10993-10 (skin irritation and sensitization) standards, providing the biocompatibility assurance required for Class I, II, and III medical device manufacturing. Additionally, it meets LFGB (German Food and Feed Code) and USP Class VI requirements for pharmaceutical and food contact applications.

Key Features & Benefits

• ISO 10993 Biocompatibility Compliant: Independently tested per ISO 10993-5 (cytotoxicity, MEM elution method) and ISO 10993-10 (irritation and delayed-type hypersensitivity), providing documented biocompatibility for medical device regulatory submissions.
• 100% Solvent-Free Formulation: Contains zero organic solvents, eliminating concerns about residual solvent extractables that could compromise medical device biocompatibility or pharmaceutical product stability.
• Zero Silicone Oil Content: Unlike conventional silicone-based release agents that can leave silicone oil residues, LK-9800-MG is completely silicone-free, preventing cross-contamination that could affect subsequent bonding, coating, or sterilization processes.
• Platinum Cure Compatible: Formulated without catalyst poisons (sulfur, amines, tin compounds) that can inhibit platinum-catalyzed addition cure systems commonly used for medical grade silicone.
• Ultra-Low Extractables Profile: The cured release film has been validated to produce minimal extractable substances, with total organic carbon (TOC) levels well below USP <643> limits for pharmaceutical water systems.
• Cleanroom-Ready: Filtered to 0.2 micron and filled under ISO Class 7 cleanroom conditions, suitable for direct use in ISO Class 7 and 8 medical device manufacturing environments.

Technical Parameters

Application Instructions

1. Mold Preparation: Clean mold with medical-grade isopropyl alcohol (IPA 70%) or validated alkaline cleaner. Rinse thoroughly with WFI (Water for Injection) or purified water. Dry completely in cleanroom environment.
2. Dilution: Using aseptic technique, dilute concentrate with sterile purified water or WFI at 1:15 to 1:25 ratio. Prepare only the volume needed for the production shift. Filter diluted solution through 0.2-micron filter if required by process validation.
3. Application: Apply using a validated clean spray system in a controlled environment. Use 2-3 light coats with 30-second intervals. Verify complete coverage under appropriate lighting.

Frequently Asked Questions (FAQ)

Q: What biocompatibility documentation is provided?
A: We provide a comprehensive Biocompatibility Summary Document including ISO 10993-5 cytotoxicity test report (MEM elution, L929 cells), ISO 10993-10 irritation and sensitization test reports, USP Class VI systemic toxicity test data, and a material characterization summary including GC-MS extractables profile.

Q: Is it suitable for implantable medical devices?
A: LK-9800-MG is validated for short-term (<24 hours) and prolonged (24 hours to 30 days) patient contact applications. For permanent implant applications (>30 days), please contact our regulatory team for specific guidance and additional testing data.

Q: Can it withstand EtO and gamma sterilization?
A: The release film is stable through standard EtO sterilization cycles (55°C, 60-80% RH) and gamma irradiation up to 50 kGy. Post-sterilization release performance has been validated through functional testing.

Q: What is the minimum order for medical grade evaluation?
A: We offer 1-liter medical grade evaluation kits including CoA, biocompatibility summary, and application protocol. A Quality Agreement and Supply Agreement are required for production supply.
