        The description of HY-F666 Silicone Foams:
                 HY-F666 Silicone foams is a soft, two-component platinum silicone flexible foam that is versatile and easy to use. HY-F666 Platinum Silicone Foams expands 5 times its original volume and develops a uniform 10 lb./cu. ft. cell structure (160 kg/m3). Vibrant colors can be achieved by adding Silc-Pigsilicone color pigments. Cured foam is high heat resistance (will resist up to 350°F/176°C), water resistant, UV resistant and resists oxidation and ozone degradation.

        HY-F666 Silicone foams applications
                  HY-F666 Silicone foams can be used for a variety of industrial and special effects applications including making foam filled appliances, padding/seat cushioning, orthotics/orthopedics, potting and encapsulation of electrical circuits and vibration dampening.

        Warning - A small amount of Hydrogen gas is released as part of the A:B reaction. Use only with adequate ventilation and do not breathe fumes. Also do not smoke or have other ignition sources in proximity to this product during mixing and pouring.

        Pouring - For best results, pour your mixture in a single spot at the lowest point of the containment field and let the mixture seek its own level.

        Handling Strength is 20 minutes with full cure in 1 hour at room temperature. Foam color will darken over time. Adding silicone pigments will help stabilize color of cured foam. To adhere Silicone Foams to other platinum silicones, best adhesion is realized when poured against newly cured platinum silicone rubber.
