DRK-RS2104

Product Overview:
DRK-00002 is a hydroxyalkyl-terminated silicone compound with a reactive CH₂OH group, optimized for use in polyurethane and crosslinking systems. Its lower hydroxyl number provides improved compatibility and surface modification, resulting in long-term flexibility, smoothness, and water resistance.

Key Benefits:

• Long-lasting slip and anti-dirt effects

• Enhances surface flexibility and weather resistance

• Promotes a stable low surface energy layer

• 100% active, transparent liquid for easy formulation

Application Fields:

• Polyurethane coatings and elastomers

• Amino resin crosslinking systems

• Surface modifiers and performance additives

Usage Guidelines:

• Slip improvement: 0.2–1%

• Anti-dirt effect: 2–6%

• Can be added during any manufacturing step

Technical Data:

• Hydroxyl number: 25–30

• Molecular weight (Mn): ~4000

• Appearance: Colorless transparent liquid

Packaging:
25 kg metal pail
