When Thiols Meet Light: Redefining the Possibilities of Efficient Curing

In the world of rapid curing and precision coatings, reaction speed, stability, and processing controllability are often difficult to achieve simultaneously. IOTA-280 Mercaptoalkyl Modified Silicone, with its highly reactive thiol functional groups and excellent photo-induced crosslinking properties, offers you an innovative platform for achieving "click chemistry"-level rapid curing under ultraviolet light. Whether it is anti-adhesion coatings, electronic encapsulation, or specialty adhesives, IOTA-280 uses light as a pen to precisely "write" performance.

Three Core Advantages, Illuminating Curing Efficiency

1. Efficient Click Chemistry, Instant Crosslinking

• Based on thiol-ene click chemistry, enabling fast and selective reactions

• Under UV light induction, crosslinking and curing are completed within 1-10 seconds, significantly improving production efficiency

• Thorough reaction with minimal by-products, ensuring high system purity

2. Excellent Stability and Weather Resistance

• Chemically stable, not prone to self-polymerization or degradation during storage and processing

• Strong weather resistance, suitable for outdoor and harsh environmental coatings

• Highly controllable and repeatable photocuring process

3. Broad Photocuring Compatibility

• Suitable for UV curing and electron beam curing systems

• Good compatibility with various vinyl silicone oils/resins, offering flexible formulation design

• Significantly improves the poor adhesion issues of traditional photocuring adhesives

Typical Physical and Chemical Indicators

Note: Specific indicators can be customized according to user needs.

Main Application Directions

 UV/Electron Beam Curable Anti-Adhesion Coatings

• Used as high-performance release agents for composite materials and rubber product molding

• Serves as paper release agents, providing uniform and stable release effects

• Smooth coating surface with controllable release force and good reusability

 Semiconductor and Optical Fiber Protective Coatings

• Acts as a UV-curable crosslinker for semiconductor encapsulation coatings

• Suitable for optical fiber coatings, improving mechanical strength and signal stability

• Rapid curing, dense coating, and excellent electrical insulation

 Silicone Rubber Curing Promotion and Adhesion Enhancement

• Improves the curing rate of condensation-type silicone rubber, enhancing production efficiency

• Addresses the shortcomings of traditional UV adhesives, such as poor adhesion and weak bonding

• Suitable for precision electronic bonding, optical component encapsulation, and other scenarios

Usage Guidelines

1. Formulation Recommendation: Mix IOTA-280 with vinyl-containing silicone oils/resins in a specific ratio (suggested thiol-to-double-bond molar ratio: 1:1 to 1:2)

2. Add Photoinitiator: Add 5-10% of a UV photoinitiator (e.g., TPO, Irgacure series) by total system weight and mix evenly

3. Coating and Curing: Apply the mixture to the substrate or inject it into a mold, then irradiate under a 200-400 nm UV lamp for 1-10 seconds to achieve complete curing

Packaging and Storage

• Packaging Specifications: 1 kg / 5 kg plastic drums (customizable upon request)

• Storage Conditions: Store in a cool, dry place, strictly protected from light and sealed

• Shelf Life: 6 months (performance must be re-tested after expiration)
