说明

属性

A slightly yellow, transparent liquid; color (Fe-Co) ≤2; density 1.31 g/cm³ (25℃); viscosity 1160±200 mPa·s (25℃); bismuth content 28±0.5%; possesses a characteristic compound odor; readily soluble in common polyurethane raw materials.

Free from restricted heavy metals, polycyclic aromatic hydrocarbons, phthalates, etc., it meets stringent environmental regulations in the United States and the European Union. It is an environmentally friendly alternative to traditional organotin, mercury, and lead catalysts, and can also be used to replace amine-tin catalysts in polyurethane foam.

应用领域

⚫ Widely used in the polyurethane industry, suitable for polyurethane elastomers and foams, especially recommended for polyurethane soft rubber, insoles, and gels.

⚫ Recommended for use in the coatings industry as a substitute for organotin compounds, suitable for two-component polyurethane coatings or one-component blocked isocyanate coatings, such as automotive refinish paints, industrial paints, and blocked coil coatings.

Usage Instructions

⚫ For use in two-component polyurethane formulations, it is recommended to add the polyol (P component) component. It is advisable to add it after dehydration and stir thoroughly.

⚫ For use in coatings, it is recommended to add it before on-site application; this will yield better results than premixing.

⚫ The general dosage is 0.02–0.8% of the PU weight.

⚫ Adding to the isocyanate component (I component) is not recommended. If it must be added, a suitability and storage stability test must be conducted first.

⚫ After use, be sure to seal and store immediately.

Storage Specifications

HDPE plastic drums, 25/200kg/drum. Store in a dry, cool warehouse, away from direct sunlight and rain. Unopened shelf life: 24 months.
