Uses&benefits

Pharmaceutical Synthesis

Liquid Silicone Rubber

Surface treatment

Electronic materials & coatings

Benefits:

Used as a group protector in the synthesis of antibiotics, antiviral drugs, and anticancer drugs.

Efficient protection: protect the active groups (e.g., hydroxyl, amino) in the drug molecule by silylation reaction, avoiding side reactions and improving synthesis efficiency.

High purity product: Reduce the generation of impurities, enhance the purity and stability of the drug, and meet the strict quality standards of the pharmaceutical industry.

Adaptation to complex reactions: maintains chemical stability at high temperatures or under strong acid conditions, applicable to a variety of drug synthesis pathways.

Benefits:

Improving Adhesion to Substrates:

This improved adhesion results in a stronger and more durable bond between the silicone rubber and the substrate. This is crucial in applications where the silicone rubber needs to withstand mechanical stress, temperature changes, or exposure to various chemicals.

Enhancing the Properties of the Silicone Rubber:

By carefully controlling the amount of HMDS added, manufacturers can tailor the properties of the silicone rubber to meet specific application requirements. This allows for the creation of silicone rubber products with optimized performance characteristics.

Facilitating Processing and Handling:

These improvements in processing and handling can lead to increased production efficiency and reduced waste. They can also enable the creation of more complex silicone rubber parts with intricate designs.

Benefits:

Improved Dispersion: HMDS treatment reduces particle agglomeration, leading to better dispersion in a matrix and enhanced composite mechanical properties.

Enhanced Hydrophobicity: HMDS makes surfaces water-repellent, crucial for moisture-resistant applications, and improves powder(sio2、Silica、Graphene、Microsilica powder) flowability.

Increased Interfacial Adhesion: HMDS strengthens chemical bonding between filler and matrix, boosting composite strength, toughness, and environmental resistance.

Benefits:

For surface treatment of electronic encapsulation materials, high temperature resistant coatings and photovoltaic materials.

Water and dirt repellency: Enhance the hydrophobicity and dirt repellency of the coating through surface silanization treatment to extend the service life of the material.

Corrosion resistance: Protect electronic components from moisture and chemical corrosion, improve equipment reliability.

Low-temperature applicability: can still form a uniform coating under low-temperature conditions, adapting to the needs of special scenarios such as photovoltaic backsheets.
