（Amino/Alkyl Functional Oligomer）Yongxiu Ecopower Chemical Special R&D
Product Description:
Crosile®-8159 is a pre-hydrolyzed, water-borne silane containing 60 % active oligomer and 40 % water. The product is supplied as a light-blue, ready-to-use liquid free of volatile organic compounds (VOC).
Key Features:
• Zero VOC – no release of flammable organics
• Flash point > 98 °C – safe for high-temperature, electrostatic or open-flame areas
• Pre-hydrolyzed – no on-site alcoholysis required; dilute only with water
• Wide compatibility – designed for water-based systems; tolerates minor solvent levels
