Controlled-release Fertilizer coatiing agents Polyester Polyol

Controlled-release Fertilizer coatiing agents Polyester Polyol

Name: Controlled-release Fertilizer coatiing agents Polyester Polyol
Brand: XINFA
Rating: 5.0 (67 reviews)

XINFA Polyester Polyol products for slow-release fertilizer coating agents, including XF-B-3, XF-B-4 and XF-270, incorporate substantial bio-based groups into the molecular structure of polyester polyols. Through performance parameter adjustments, the resulting coating agents combine the outstanding weather resistance of polyurethane resins-delivering superior controlled-release effects and extending fertilizer release cycles-while also possessing the outstanding degradability of bio-based groups: rapidly breaking down into small molecules to meet environmental requirements. They represent the preferred raw material for producing controlled-release fertilizer coating agents.
