Long Chain Alkyl Silicone 2000cst CAS 68554-54-1 Release Agent for PU Leather Synthetic
2000cst Long Chain Alkyl Silicone (CAS 68554-54-1) is high viscosity long-chain alkyl modified silicone fluid. Alkyl modification greatly improves compatibility with polyurethane systems and organic solvents. In the production of synthetic PU leather, it migrates to the interface between PU and release paper, providing lasting release property. It will not cause poor adhesion of post-processing layers. It is a preferred functional additive for wet-process and dry-process artificial leather manuf
Product Overview
2000cst Long Chain Alkyl Silicone is specially developed modified silicone fluid for synthetic PU leather industry. Traditional dimethyl silicone oil is poorly compatible with PU slurry, easily causing blooming, printing failure and poor coating adhesion. Thanks to long-chain alkyl modification, this product can disperse evenly in polyurethane solutions. It forms an ultra-thin isolating film at the contact interface, ensuring smooth demolding. Meanwhile, it retains good surface activity without interfering with post-processing procedures of synthetic leather.
Key Features
- Viscosity: 2000cst, Long Chain Alkyl Modified Silicone Oil, CAS 68554-54-1
- Outstanding compatibility with PU resin, DMF and common organic solvents
- Reliable release property for dry-process and wet-process synthetic leather
- Reduce pinholes, streaks and other surface defects on PU leather
- Will not cause surface blooming, maintain good adhesion for printing and laminating
- Stable performance under conventional synthetic leather processing temperature
Main Applications
- Release additive for wet PU leather, microfiber synthetic leather
- Functional raw material for dry PU artificial leather surface treatment formula
- Anti-sticking auxiliary for polyurethane film and release paper separation
- Slip modifier for various polyurethane coating formulations
Usage Guidance
Can be directly blended into PU slurry or dissolved in solvent as release agent component. Recommended dosage: 0.2% ~ 1.2% relative to PU resin weight. Adjust dosage based on leather thickness, peeling requirements and production speed. Complete small-scale trial production to test release effect and surface adhesion before mass production.
Storage & Package
