Platinum Cure Silicone Foamsfor filling Description of Platinum Cure Silicone Foams for filling Platinum Cure Silicone Foams is a soft, two-component platinum silicone flexible foam that is versatile and easy to use. HY-F663 Platinum Silicone Foams expands 3.5 times its original volume and develops a uniform 20 lb./cu. ft. cell structure (320 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. Typical Applications for Platinum Cure Silicone Foams for filling Platinum cure 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.

These products have a limited shelf life and should be used as soon as possible. Good room size ventilation is essential. Wear safety glasses, long sleeves and rubber gloves to minimize contamination risk. Cure Inhibition - Addition cured silicones may be inhibited by certain contaminants such as sulfur, polyesters,certain wood surfaces, epoxies, urethane rubber and tin catalyzed silicones resulting in tackiness at the pattern interface or a total lack of cure throughout the mold. If compatibility between the rubber and the surface is a concern, a small-scale test is recommended. Apply a small amount of foam onto a non-critical area of the pattern.Inhibition has occurred if the matrerial is gummy or uncured after the recommended cure time has passed. This product will not cure against tin-based silicone rubbers. Applying A Release Agent - Silicone Foams will stick to some surfaces and a release agent may be necessary to facilitate demolding. When casting Silicone Foams into or over other platinum silicones, apply Ease Release 200 prior to applying foam. SHELF LIFE: 8-10 months when stored under 24â?? in original unopened packages. PACKAGE: Packed in 20kg/pail + 20kg/pail and 200kg/pail + 200kg/pail. -
