Bio-SAH 362 is a high-performance hydrolysis stabilizer in white powder form, specifically developed for polyester polyol-based systems. Polyester polyols are widely used in polyurethane applications such as flexible foams, coatings, adhesives, and sealants. However, due to the presence of ester bonds, these materials are highly susceptible to hydrolysis, especially under conditions of humidity, elevated temperature, or long-term environmental exposure.
Hydrolytic degradation leads to chain scission, reduced molecular weight, deterioration of mechanical properties, and potential failure of end-use products. Bio-SAH 362 provides an effective solution by stabilizing the polymer structure and preventing further degradation.
High-efficiency hydrolysis stabilization for polyester polyols
White powder form for clean formulation and easy handling
Excellent compatibility with PU systems
Improves long-term durability and mechanical stability
Enhances resistance to moisture and heat
Suitable for a wide range of polyurethane applications
Professional-grade formulation for consistent performance
Bio-SAH 362 is widely applied in polyester polyol-based systems:
Polyurethane flexible foams
PU coatings (industrial and protective)
Adhesives and sealants
Elastomers and casting systems
Applications requiring high durability and moisture resistance
Bio-SAH 362 contains reactive functional groups that selectively react with carboxylic acid end groups generated during hydrolysis. This reaction forms stable structures that eliminate the catalytic sites responsible for further degradation. By interrupting the hydrolysis cycle, the additive maintains polymer integrity, preserves molecular weight, and ensures long-term performance of the final product.
Recommended dosage: typically 0.5% – 2.0% depending on formulation
Can be added during polyol blending or system formulation
Suitable for standard polyurethane processing conditions
Store in a cool, dry environment and avoid moisture exposure. Keep packaging tightly sealed after use. Follow standard industrial safety procedures during handling.
