A two-component spray foam system based on blowing factor 141 B, designed for a target total density of 42-45 kg/m³. Foam properties When BC 700 Polyol reacts with BC 768 Isocyanate, it forms a crosslinked structure characterized by: very good adhesion to conventional surfaces. Dimensionally stable. It has the best insulation properties (thermal insulation).
- Uses
- Production of spray-applied rigid polyurethane foam for thermal insulation.
- Suitable for building envelope insulation including walls, roofs, attics, and ceilings.
- Ideal for cold rooms, refrigerated storage, and HVAC insulation applications.
- Can be used for industrial and domestic thermal insulation where on-site foaming is required.
- Applicable over concrete, metal, wood, and polymeric surfaces due to strong adhesion properties.
Key Properties / Design Features
- Two-component polyurethane system expanded using 141B blowing agent.
- Designed for spray-in-place applications, forming a seamless insulation layer.
- Target foam density: 42–45 kg/m³, ensuring durability and high mechanical strength.
- Crosslinked cellular foam structure offering exceptional thermal insulation.
- Very good adhesion to common construction substrates (metal, concrete, wood, etc.).
- Dimensional stability under normal temperature/humidity changes.
- Closed-cell foam structure for enhanced moisture resistance and low thermal conductivity.
- Reduces thermal bridges and air leakage due to monolithic spray application.
- Lightweight, fast-curing system supporting efficient on-site installation.
