Rigid Foam Spraying Compound, WANEFOAM®325
The WANEFOAM®325 (Type I) polyurethane rigid foam spraying coating is a fast – curing system. After molding, it can bear loads immediately, which can meet the requirements of most spraying and insulation construction projects.
This technical manual applies to WANEFOAM® 325 Type I, II, and III formulations. For product differentiation, please refer to the comparison table below.
1. Product Overview
WANEFOAM® 325 (Type I) is a high-performance rigid polyurethane foam spray system formulated with an ultra-low thermal conductivity, environmentally friendly blowing agent. When combined with WANNATE® 2208 isocyanate component, it produces foam products with exceptional flame retardancy.
Key Features:
Versatile Substrate Compatibility: Bonds strongly to concrete, brick, wood, and other substrates.
Superior Stability: Excellent dimensional stability (≤1.5% at 70°C/48h) and closed-cell structure (≥90%).
Flame Retardancy: Class B2 fire rating (GB 8624-2012) with an oxygen index ≥26% (GB/T 2406.2-2009).
