With a professional production team, we are able to meet the needs of the majority of our customers. Welcome to wholesale bulk top-quality methyl hydrogen silicone oil cas 63148-57-2 from our factory.
Product Overview
Methyl hydrogen silicone oil (polymethylhydrosiloxane, PMHS) is a colorless transparent oily liquid with a polysiloxane backbone (-Si-O-) bearing methyl groups and reactive Si-H bonds. Under catalyst action (e.g., chloroplatinic acid, organic tin), Si-H bonds crosslink with hydroxyl, amino, or vinyl groups to form a three-dimensional silicone water-repellent network. This product delivers hydrogen content >1.58% and viscosity of 28–32 mm²/s, representing a high-hydrogen general-purpose grade.
Guolan New Materials produces high-hydrogen silicone oil using mature continuous polymerization technology, with hydrogen content >1.58% and acid value <5 ppm, with tight control over volatile matter and low-molecular-weight fractions. The product is widely used in textile water-repellent finishing, penetrating building waterproofing, addition-cure silicone rubber crosslinking, paper release coatings, and glass fiber treatment. Our product balances high active Si-H content with batch-to-batch consistency, helping downstream customers reduce formulation debugging costs and improve process reproducibility.
Guolan New Materials operates a dedicated organosilicon production base in the Dongying Port Economic Development Zone, Shandong Province, with an annual capacity of 5,000 tons. Our rigorous quality control system ensures consistent hydrogen content, viscosity, and acid value across every batch, backed by ISO 9001:2015 certification. The product is shipped as non-hazardous general cargo from Qingdao, Shanghai, and Tianjin ports, serving customers across Asia, North America, the Middle East, and Southeast Asia. OEM private labeling and custom viscosity services are available.

Key Strengths
- Consistently High Hydrogen Content - Hydrogen content >1.58% provides abundant reactive Si-H crosslinking sites per molecule for high crosslink density and long-lasting water repellency. Tight batch-to-batch hydrogen content variation ensures reproducible downstream formulations and reduces process adjustments caused by raw material fluctuation.
- Low Acid Value & Low Impurities - Acid value <5 ppm prevents fabric yellowing and equipment corrosion. Low volatile matter (<2%) reduces VOC emissions and meets environmental requirements. Ideal for high-end applications sensitive to color and purity.
- Versatile Multi-Application Performance - Suitable for textile water-repellent finishing, penetrating building waterproofing, silicone rubber crosslinking, paper release, and glass fiber treatment - reducing multi-supplier procurement management costs with one versatile product.
- Complete Quality Documentation - Every shipment includes a Certificate of Analysis (COA), Safety Data Sheet (SDS), and Technical Data Sheet (TDS).
- Flexible Packaging & OEM Services - Available in both 200L iron drums (200 kg) and 1000L IBC totes (1000 kg). Private drum label printing supported. Custom viscosity and hydrogen content grades can be matched to specific downstream industry process requirements.
- Non-Hazardous, Easy Logistics - Classified as non-hazardous general cargo, resulting in lower logistics costs and simpler booking and customs clearance procedures. Shipped from Qingdao, Shanghai, and Tianjin ports, supporting both FCL and LCL sea freight.
Key Applications
Textile Water-Repellent Finishing
Used for water-repellent finishing of cotton, polyester, nylon, and blended fabrics. Under catalyst (organic tin or platinum), Si-H bonds react with fiber surface hydroxyl groups to form a crosslinked silicone film that lowers surface tension, causing water to bead and roll off. Treated fabrics retain breathability and soft hand feel without yellowing or affecting dye fastness.
Penetrating Building Waterproofing
When diluted and applied to concrete, mortar, masonry, and aerated blocks, it penetrates into capillary pores; Si-H groups hydrolyze and chemically bond with surface hydroxyl groups to form a durable water-repellent layer. It does not change surface appearance or vapor permeability, and reduces water absorption, efflorescence, freeze-thaw damage, and chloride ion penetration.
Addition-Cure Silicone Rubber Crosslinker
Serves as a crosslinker component for platinum-catalyzed addition-cure silicone rubber and RTV silicone. Si-H groups undergo hydrosilylation with vinyl silicone rubber to form a three-dimensional network. Fast cure speed and low shrinkage make it ideal for precision molding and electronic potting applications.
Paper Release Agent & Glass Fiber Treatment
Used as an anti-sticking release coating for packaging and industrial paper, as well as glass fiber sizing and ceramic silicone water-repellent treatment. Uniform film formation and excellent release properties do not affect subsequent printing or lamination.
FAQ
Q: What is your minimum order quantity (MOQ) for trial orders?
A: Our standard MOQ is one 200L iron drum (200 kg net weight). For first-time customers evaluating the product, smaller sample packs (1–5 kg) are available upon request. This lets you run laboratory trials before committing to a full drum.
Q: Can you supply both small trial batches and full container loads?
A: Yes. We support the full range - from 1 kg lab samples to 200L drums, 1000L IBC totes, and full 20'FCL shipments. Our 5,000-ton annual capacity ensures consistent supply whether you are testing a new formulation or scaling to production volume.
Q: What quality documentation is included with each shipment?
A: Every shipment includes a factory Certificate of Analysis (COA) listing hydrogen content, viscosity, acid value, pH, density, refractive index, and flash point. Safety Data Sheet (SDS) and Technical Data Sheet (TDS) are also provided.
Q: What industries is this general-purpose grade suitable for?
A: This versatile grade is formulated for broad applications: textile water-repellent finishing, penetrating building waterproofing, addition-cure silicone rubber crosslinking, paper release coatings, and glass fiber treatment. It is a cost-effective choice when you need one reliable product across multiple downstream processes.
Q: How does this high-hydrogen grade compare to standard low-hydrogen silicone oil?
A: With hydrogen content >1.58%, this grade delivers nearly double the reactive Si-H sites of standard grades (<1.0% hydrogen). The result is higher crosslink density, stronger water repellency, and better cure efficiency - ideal for applications demanding maximum performance rather than light-duty treatment.
Q: What is the shelf life and storage condition?
A: When stored in original sealed packaging in a cool, dry, ventilated warehouse, shelf life is 12 months from manufacture. Keep containers tightly sealed and away from moisture, acids, alkalis, and oxidizers. Moisture exposure hydrolyzes Si-H bonds and reduces active hydrogen content over time.
