On October 17, 2025, Silok held a small offline technical seminar on silicone polyurethane film-forming agents at its Huaxinyuan store in Guangzhou. At the event, detailed information about silicone polyurethane film-forming agents was presented to customers, including the technical principles, effects, advantages, and usage tips. Customers were given practical application advice and experienced sample demonstrations for a more intuitive understanding, helping them apply silicone polyurethane film-forming agents more scientifically and effectively in real business scenarios, thereby enhancing the performance and value of the raw materials.

This event mainly introduces how SiCare polyurethane resin film-forming agents balance the challenges in makeup of needing to form a film quickly, last long, and adhere precisely!

Basic Principle of SiCare Silicone Polyurethane Film-Forming Agent: It is formed by combining flexible long-chain bis-hydroxyethoxypropyl polydimethylsiloxane with IPDI to create a polyurethane carbamate.

Silicone polyurethane, as a polymer that combines the advantages of polyurethane and organosilicon, can form an extremely thin soft film with excellent adhesion, elasticity, and bonding properties.

Silicone Polyurethane and Biocompatibility & Safety:

Organosilicon-modified polyurethane film-forming agents typically have a high molecular weight (>500 g/mol), making it difficult to penetrate healthy skin’s stratum corneum and greatly reducing the risk of skin irritation or allergic reactions.

Safety Verification:

• Organosilicon materials are widely used in cosmetics, with long-term safety validation
• The use of polyurethane in anticoagulant coatings for medical devices and biomimetic skin indirectly proves its good biocompatibility
• Compliant with ISO 10993 series biological evaluation standards

Performance Advantages of SiCare Silicone Polyurethane Film-Forming Agent:

• Ultimate Skin Feel -- Soft and full texture, low friction coefficient (0.02-0.05), providing an extremely silky and soft touch (when forming a film with rigid materials)
• Excellent Breathability -- Micro-phase separation structure can design breathable channels, water vapor transmission rate ≥500 g/(m²·24h)
• Long-Lasting Abrasion Resistance -- High gloss, excellent dry and wet rubbing resistance and wear resistance, surface is hydrophobic and stain-resistant
