Product catalog summary
Introduction
This document provides technical specifications and usage instructions for SILFOAM750 and SILFOAM750B2, high-performing soundproofing sealing polyurethane foams. These products are designed for the assembly of timber, PVC, or aluminium door and window frames and offer perfect adhesion to various building materials.

Specifications
  • Reaction to Fire: SILFOAM750 is classified as B3 and SILFOAM750B2 as B2 according to DIN 4102-1.
  • Emissions: Both products are classified EC1PLUS for low emissions of organic volatile compounds.
  • Acoustic Insulation: Provides ≥ 63 dB soundproofing for joints of 10 mm and 20 mm thickness.
  • Temperature Resistance: Once hardened, SILFOAM750 withstands -40 to +90 °C, while SILFOAM750B2 withstands -40 to +80 °C.
  • Application Temperature: SILFOAM750 can be applied between +5 to +35 °C, and SILFOAM750B2 between +10 to +35 °C.

Instructions for Use
Ensure the use of appropriate Personal Protective Equipment (PPE) and consult the technical and safety data sheets before use. The substrates should be clean and free of contaminants. Optimal performance is achieved at approximately +20°C. Shake the can vigorously before use and after any interruptions. The foam is self-expanding; spray with water to aid expansion and uniformity. Clean the gun thoroughly after use.

Warnings
  • Use only in ventilated environments.
  • The product is flammable; avoid inhalation and contact with eyes and skin.
  • Dispose of contents and containers according to local regulations.
  • Do not expose to temperatures exceeding 50 °C.
  • For gaps greater than 30mm, apply the foam in several passes.

Technical Data
  • Film Formation Time: 6 - 10 minutes at 23 °C / 50% RH.
  • Cutting Time: 20 - 40 minutes at 23 °C / 50% RH.
  • Complete Hardening Time: 60 minutes at 23 °C / 50% RH.
  • Thermal Conductivity: 0.030 - 0.035 W/(m∙K).
  • Air Permeability: a ≤ 0.1 m³/(m∙h∙daPa²/³).
  • Water Vapour Resistance Factor: 20.
  • Water Vapour Transmission: 1.4 m for 70 mm thickness.

Storage and Stability
The product remains stable for 18 months if stored in original packaging in a dry, covered place, in an upright position. Check the expiry date on the packaging.

PLATES AND ANGLE BRACKETS POST BASES SILENT FOAM HIGH PERFORMING SOUNDPROOFING SEALING POLYURETHANE FOAM • Reaction to fire B3 (SILFOAM750) and B2 (SILFOAM750B2) according to DIN 4102-1 • Perfect adhesion to any building material EPS and XPS sheets • Airtight even after trimming thanks to closed-cell structure • Classified EC1PLUS for emissions of organic volatile compounds according to GEV (SILFOAM750) test procedure SCREWS AND FASTENERS FOR TERRACES • For assembly of timber, PVC or aluminium door and window frames GLOVES INCLUDED INSTRUCTIONS FOR USE It is always advisable to have the correct Personal Protective Equipment (PPE) and to consult the technical data sheet and safety data sheet before starting the supply. The substrates must be resistant, clean, free of oil and grease, dust and dirt in general. For optimal performance work at a temperature of approximately +20°C. Immerse the can in warm or cool water to raise or lower the temperature of the mix. Shake the can energetically at least 15-20 times before using and repeating this operation after the processing interruptions, if any. Screw the cylinder to the gun. The working position of the cylinder is with the valve facing downwards. Carefully dose the amount of product into the cavity, the foam is self-expanding and increases its volume before it fully hardens. Spraying the foam with water aids the expansion process and helps create a more uniform cell structure. After use, thoroughly clean the gun to remove foam residue. Only for SILFOAM750 Use only in ventilated environments Flammable product Do not breathe vapours/aerosols Avoid contact with eyes and skin Keep out of reach of children Dispose of contents/container in accordance with local regulations Follow the information on the safety data sheet Pressurized container. Protect from sunlight and do not expose to temperatures exceeding 50 °C. Do not pierce or burn, even after use • For gaps greater than 30mm, extrude the foam in several passes ROOF ELEMENTS SEALANTS, TAPES AND PROFILES CHEMICAL AND METAL ANCHORS GLOVES INCLUDED Aerosol 1.
