Description
INSONO AF3 adhesive is a homogeneous solvent free, low odour, acrylic latex emulsion based adhesive.
UNITS PER SKID: 36
SIZE: 19 GAL
Material Use:
INSONO AF3 ADHESIVE is a solvent-free, low-odour, acrylic latex emulsion adhesive specifically designed for the interior installation of INSONO AF3 acoustic membranes. It is formulated to provide strong adhesion to a variety of construction substrates while maintaining ease of application and environmental safety due to its low VOC content and non-flammable nature.
System Components:
This adhesive is used as part of a soundproofing system in conjunction with the INSONO AF3 acoustic membrane. It acts as the bonding agent between the membrane and the substrate. No primer is required, and the adhesive is ready-to-use without any mixing. The system includes:
- Base Layer: Properly prepared substrate (concrete, plywood, screeds, etc.)
- Adhesive Layer: INSONO AF3 ADHESIVE
- Top Layer: INSONO AF3 acoustic membrane
Applications:
INSONO AF3 ADHESIVE is intended for interior use only and is suitable for bonding acoustic membranes to a variety of substrates including:
- Fully cured concrete (minimum 28 days old)
- Cementitious screeds and mortar beds
- Gypsum-based concrete
- Cement-based levelling plasters
- Exterior-grade plywood
Application Details:
The adhesive is applied directly to the substrate using a 10 mm (3/8 in) nap roller. The membrane must be installed while the adhesive is still fresh and wet; it should not be allowed to skin over or dry before membrane placement. The recommended application temperature range is between 10 °C (50 °F) and 35 °C (95 °F). The wet open time is approximately 30 minutes, and the curing time ranges from 2 to 6 hours under ideal conditions (23 °C / 73 °F and 50% relative humidity).
Coverage:
Each 19 L (5 US gal) container covers approximately 65 to 84 m² (688 to 904 ft²), depending on surface texture and application technique. This equates to a coverage rate of approximately 0.21 to 0.28 Gal / 100 ft².
Special Notes:
- The adhesive is non-flammable and has freeze/thaw stability down to 5 °C (41 °F).
- It provides a minimum bond strength of 0.31 MPa (45 psi) to the substrate and 0.21 MPa (30 psi) to the INSONO AF3 membrane.
- Tools and uncured adhesive can be cleaned with water. Once cured, cleaning requires solvents such as mineral spirits, Varsol, or xylene.
- The product has a shelf life of 24 months when stored in its original sealed container in a ventilated area, away from heat, frost, and direct sunlight.
- This adhesive is not UV stable and is intended for interior use only.
- It is important to ensure that the substrate is dry, clean, and free of moisture or alkaline conditions before application to ensure optimal performance.
This adhesive is a critical component in acoustic flooring systems and should be used strictly according to the manufacturer’s guidelines to ensure proper bonding and long-term performance.
