Applications with different hydrogen contents

By adjusting the hydrogen content (Si-H bond density) and molecular weight, hydrogen-containing silicone oils can precisely match the performance requirements of different silicone products:

  • High hydrogen content model: High crosslinking efficiency, suitable for silicone rubber products requiring high strength and hardness (such as medical catheters, electronic seals);
  • Low hydrogen content model: Moderate crosslinking density, suitable for products requiring flexibility and high elasticity (such as organic silicone pressure-sensitive adhesives for medical aesthetic repair patches, cosmetic smoothers);
  • Different molecular weight hydrogen-containing silicone oils can also regulate curing speed and gel layer thickness, meeting the needs of various processing methods such as coating, compression molding, and injection molding.

Why Choose Hydrogen Silicone Fluid?

Hydrogen silicone fluid brings reactivity and control straight into your formulation. Its active Si–H groups enable fast crosslinking, precise structure tuning, and strong performance at low dosage. Easy to blend with silicones, polymers, and modifiers, it delivers reliable results in rubber, gels, coatings, and functional additives—making it a smart, efficient choice for upgrading existing products or building next-level systems.

Hydrogen-containing silicone oil vs. Traditional crosslinking agents

Comparison Dimension Hydrogen-containing Silicone Oil (Hydrosilylation Crosslinking) Peroxide Crosslinking Agent Amine Crosslinking Agent
Curing By-products No small molecule release, high purity Produces small molecule impurities, has odor Prone to amine residue, highly irritating
Curing Temperature Room temperature ~ 120°C (efficient at low temperatures) 150~200°C (high-temperature curing) Cures at room temperature, but slow
Product Applicability Medical, cosmetics, precision electronics Industrial rubber products (low purity requirements) Epoxy resins (non-silicone systems)
Aging Resistance Excellent (stable from -60°C to 250°C) Average (prone to yellowing at high temperatures) Poor (insufficient temperature resistance)
Biocompatibility Meets medical/cosmetic standards Risk of residue, not suitable for human contact Highly irritating, prohibited

Precautions of choosing MQ resin

Application

Clearly define your system: addition-cure silicone rubber, RTV, silicone gel, coatings, defoamers, release agents, surface treatment, or reactive modification.

Reaction System / Processing Conditions

Confirm the H content you need, the curing mechanism (hydrosilylation or modification), catalyst type, processing temperature, and mixing or reaction conditions.

Target Performance

Specify your objective: crosslink density, softness or elasticity, transparency, reaction speed, final mechanical properties, or long-term stability.

Our silicone fluid can be used in different product areas

Silicone fluid usually refers to a linear polysiloxane product that remains liquid polymerized siloxane at room temperature. It is generally divided into two categories: methyl silicone fluid and modified silicone fluid. The most common and typically used silicone oil – methyl silicone oil, whose organic groups are all methyl groups, methyl silicone oil has good chemical stability, insulation, hydrophobic properties. With the different number of chain segments n, the molecular weight increases, and the viscosity increases, so silicone fluid can have different viscosities.
