Changfu Chemical Oxetane Organosilicon Curing Agent: High Activity, Low Shrinkage, and High Temperature Resistance — The Preferred Choice for Demanding Environments.

In an era where the pursuit of high performance and reliability in photocurable materials continues to intensify, Changfu Chemical introduces its oxetane organosilicon curing agents — Changfu^® BOT12 and Changfu^® OTC4. Through innovative molecular design, these products successfully combine the high reactivity of oxetane chemistry with the superior characteristics of organosilicon materials, establishing a new benchmark for high-end industrial applications.

Key Product Advantages:

l  High Reactivity: The significant ring strain in the oxetane structure enables rapid cationic ring-opening polymerization, substantially enhancing UV curing efficiency.

l  Low Volume Shrinkage: Bond length extension during ring-opening polymerization effectively compensates for shrinkage stress, resulting in strong adhesion and minimal internal stress.

l  Excellent Processability: Low viscosity ensures easy handling and processing, making it suitable as a high-efficiency reactive diluent.

l  High Conversion Rate: The curing process exhibits minimal sensitivity to oxygen inhibition, achieving thorough conversion and stable performance.

Functional Role:

Acting as both a performance accelerator and modifier, oxetane plays multiple enhancing roles in epoxy and other cationic photocuring systems:

n  Significantly increases curing speed

n  Effectively reduces shrinkage

n  Improves material toughness

n  Enhances substrate adhesion

n  Enables viscosity adjustment

Typical Applications:

Ideal for harsh environments that demand exceptional reliability and durability, including:

u  High-End Electronic Packaging & Protection: LED encapsulation, chip protective coatings, PCB conformal coatings.

u  High-Performance Optical Coatings: Anti-fingerprint, anti-reflective, and hard coatings for mobile device screens, automotive displays, and eyewear.

u  High-Temperature Resistant Adhesives: Suitable for bonding and sealing in applications requiring long-term thermal endurance.

u  High-Precision 3D Printing: Meets stringent requirements for dimensional accuracy and minimal shrinkage in photocurable additive manufacturing.

With their unique combination of properties, Changfu's oxetane organosilicon curing agents offer an advanced material solution for high-end manufacturing, serving as a key enabler for high-performance and high-reliability products.
