Methyl Capped Allyl Polyether CAS 52232-27-6 Low Hydroxyl Polyether Surfactant Coating Leveling Agent Defoamer Textile Softener Raw Material

Core Performance Advantages

1. Methyl end-capping design: Completely shield terminal hydroxyl active hydrogen, eliminate side condensation reaction during hydrosilylation with hydrogen-containing silicone oil, high transparency of modified silicone oil finished product, no turbidity, no gel precipitation.

2. Stable reactive double bond: Allyl terminal double bond has high reaction activity, complete grafting reaction with Si-H bond, high grafting rate of polyether segment, stable hydrophilic-lipophilic balance of silicone oil.

3. Ultra-low impurity content: Ultra-low residual alkali and moisture, protect platinum catalyst activity during silicone synthesis, reduce catalyst dosage and production cost.

4. Excellent temperature resistance: Better oxidation stability than ordinary hydroxyl polyether, finished silicone oil has stronger high-temperature anti-yellowing performance.

5. Wide solvent compatibility: Compatible with aqueous system, solvent-based coating system, polyurethane raw material system, no phase separation after compounding.

6. Good low-temperature performance: Low pour point, no wax precipitation in winter transportation and storage, easy pumping and feeding.

Detailed Application Fields

1.1 Polyether Modified Silicone Oil Industry (Core Application)

Used as exclusive reactive monomer for hydrosilylation reaction with hydrogen-containing silicone oil to produce water-soluble silicone oil, organosilicon wetting agent, silicone defoamer, silicone textile softener, silicone foam stabilizer. Solve the problems of yellowing, turbidity and poor storage stability of traditional hydroxyl polyether modified silicone oil.

1.2 Polyurethane Foam Industry

Serve as high-stability PU foam stabilizer / cell opener for flexible foam, rigid foam, slow-rebound foam. Uniform foam pore structure, good air permeability, effectively avoid foam collapse and shrinkage during foaming, adapt to high-temperature foaming process.

1.3 Industrial Coating & Ink Additives

High-performance coating leveling agent, slip agent, anti-cratering agent raw material. Grafted silicone additives improve coating surface smoothness, scratch resistance, substrate wettability, reduce surface tension of water-based paint and solvent-based paint.

1.4 Textile Dyeing & Finishing Agent

Synthesize hydrophilic silicone softener, antistatic finishing agent, fabric moisture-permeable finishing agent. Endow cotton, polyester, blended fabrics with soft hand feel, anti-static, sweat-wicking breathable performance, no oil floating on fabric surface.
