Platinum Cure Silicone Foams
Description of Platinum Cure Silicone Foams
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-Pig silicone 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
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.

PROCESSING RECOMMENDATIONS of Platinum Cure Silicone Foams
Store and use at room temperature (73°F/23°C). 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.
IMPORTANT: To ensure thorough coverage, lightly brush the release agent with a soft
brush over all surfaces. Let the release agent dry for 15 minutes.Because no two applications are quite the same a small test application to determine suitability for your
project is recommended if performance of this material is in question.
MEASURING & MIXING.
Mixing - Mixing can be done by hand or using a drill and a mixer attachment such as a "squirrel" mixer. After dispensing required amounts of Parts A and B into mixing container, mix thoroughly for 30 seconds. Stir quickly and deliberately, making sure you scrape the sides and bottom of the mixing container several times. Be careful not to splash material out of the container. Remember foam cures quickly. Do not delay between mixing and pouring. Elevated temperatures will result in a reduced pot life and cure time.
SHELF LIFE:8-10 months when stored under 24℃ in original unopened packages.
PACKAGE:Packed in 20kg/pail + 20kg/pail and 200kg/pail + 200kg/pail.
