BASF WALLTITE® Max R Regular Reactivity Closed-Cell Spray Foam Insulation Resin (B-Component), 500 lb
Regular price $1,699.44WALLTITE Max R B-Component Closed-Cell Spray Foam Resin (500 lb)
BASF WALLTITE® Max is a closed-cell, medium-density spray foam insulation resin (B-component) designed to be mixed 1:1 by volume with BASF ELASTOSPRAY 8000A isocyanate to create high-quality SPF insulation. It delivers strong thermal performance (R-7.4) while helping control air and moisture infiltration for more efficient, resilient building envelopes.
Key Features:
- Closed-Cell Performance: Produces medium-density SPF (1.8–2.0 pcf) with strong thermal value (R-7.4).
- Designed for System Mixing: Part B resin/polyol intended for equal-volume mixing with BASF ELASTOSPRAY 8000A isocyanate.
- Fast Application Capability: Up to 4 in maximum lift per pass, with back-to-back passes up to 3.5 in with no dwell time required.
- Air & Moisture Control: Helps control air infiltration and moisture infiltration for improved envelope performance.
- Code/Assembly Approvals: Includes comprehensive NFPA 285 and UL 263 fire-rated assembly approvals with code compliance reports.
