Description

Siloxanes and Silicones, di-Me, 3-hydroxypropyl group-terminated, reaction products with 1,6-diisocyanatohexane homopolymer and 2-oxepanone homopolymer 2-(1-oxo-2-propenyl)oxyethyl ester is a specialized, high-performance hybrid polymer that combines the flexibility and thermal stability of silicones with the toughness and adhesion properties of polyurethanes and polycaprolactones. This engineered material is crucial for formulators seeking to create durable, flexible, and biocompatible coatings, adhesives, and sealants with enhanced surface compatibility. It is primarily targeted at advanced manufacturing sectors including medical device coatings, high-performance adhesives, and specialty protective finishes where material reliability and performance under stress are paramount.

Application

• Medical Device Coatings: Used as a key component in biocompatible, lubricious, and protective coatings for catheters, guidewires, and other implantable or insertable devices.
• High-Performance Adhesives & Sealants: Serves as a toughening agent and adhesion promoter in formulations requiring excellent flexibility, moisture resistance, and bond strength to diverse substrates.
• Specialty Release Coatings: Employed in industrial and graphic arts applications where a durable, yet releasable, surface is needed.
• UV-Curable Resin Modifier: Acts as a reactive oligomer to enhance the flexibility, impact resistance, and adhesion of UV-curable coatings and inks.
• Biocompatible Elastomers: A precursor for synthesizing soft, flexible elastomers used in wearable medical sensors or soft robotics components.
• Fiber & Textile Finishes: Imparts durable softness, water repellency, and abrasion resistance to technical textiles and nonwovens.

Quality Control

Our production of this advanced hybrid polymer adheres to a rigorous quality management system. Each batch is characterized using advanced analytical techniques including GPC, NMR, and FT-IR to confirm structure, molecular weight distribution, and functional group content. Certificates of Analysis (COA) detailing specific parameters such as acrylate equivalent weight, viscosity, and residual isocyanate content are provided to ensure consistency and performance for your critical applications. We support compliance with relevant regulatory frameworks for medical and industrial use.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15-25°C (59-77°F). This material is light-sensitive and easily oxidized; it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term stability and to minimize viscosity increase or gelation. Keep away from heat, sparks, and open flame.
