Product Description What is HCR silicone? Heat Cured Rubber is a silicone elastomer formed of straight chains with very high molecular weight. The system will be cured with either an organic peroxide crosslinker, or a platinum catalyst. HCR offers great temperature and aging resistance. Properties Heat Cured Rubber elastomers have outstanding properties and are far superior to conventional organic elastomers. They exhibit exceptional mechanical strength at temperature and can be used at temperatures ranging from -50°C to +300°C. The aging resistance of these elastomers highlights their fundamental qualities such as the fact that they are chemically inert, their photo-oxidative stability and the absence of residual reactive groups once cured. Related applications HCRs outstanding properties are used in many different industrial applications: sealing and piping in fluid circuitry (joints for building construction and aeronautical applications, automotive gaskets, boots and hoses), electrical protection (office equipment safety cables and insulators for electrotechnical applications, spark plug boots, cables and connectors for automotive application), food, pharmaceutical and biomedical applications (tubes, profiled sections). The addition of various additives opens unlimited for customization of HCRs to create solutions to all kind of existing and new applications in Aerospace, Automotive, Healthcare, Oil & Gas, Construction, Electronics. Most recent examples are heat transfer additives for Electrical Vehicles, electrical conductive materials for Power or Consumer Electronics and also antibacterial solutions for Healthcare applications.

Hardness 26 Shore A Tensile Strength (N/mm2) 60+/- 10 Elongation (%) 600+/-50 Tear Strength (N/mm) 27+/-2 How to use 1.Substrate Preparation The surface of the original should be clean and free of loose material. If necessary, and in particular with porous substrates, use a suitable release agent such as petroleum jelly or soap solution. 2. Mixing Thoroughly stir Part A (silicone base) before use as filler separation may occur upon prolonged storage. Weigh 100 grams Part A (silicone base) and 3 grams Part B (curing agent) in a clean container. Mix together until the curing agent is completely dispersed in the base. Hand or mechanical mixing can be used, but do not mix for an extended period of time or allow the temperature to exceed 35°C (95°F). Mix suitably small quantities to ensure thorough mixing of the par A (silicone base) and part B (curing agent). It is strongly recommended that entrapped air be removed in a vacuum chamber, allowing the mix to completely expand and then collapse. After a further 1-2 minutes under vacuum, the mix should be inspected and can be used if free of air bubbles. A volume increase of 3-5 times will occur on vacuum de-airing the mixture, so a suitably large container should be chosen. Caution: prolonged vacuum will remove volatile components from the mix and may result in poor thick section cure and non-typical properties. Note: If no vacuum de-airing equipment is available, air entrapment can be minimized by mixing a small quantity of par A (silicone base) and part B (curing agent), then using a brush, painting the original with a 1-2mm layer. Leave at room temperature until the surface is bubble free and the layer has begun to cure. Mix a further quantity of base and curing agent and proceed as follows to produce a final mold. 3. Pouring the Mixture and Curing Pour the mixed Par A (silicone base) and Part B (curing agent) as soon as possible onto the original, avoiding air entrapment. The catalyzed material will cure to a flexible rubber within 24 hours at room temperature (22°C- 24°C/ 71.6°F - 75.2°F) and the mold can then be separated from the original. If the working temperature is significantly lower, the cure time will be longer. If the room temperature or humidity is very high, the working time of the catalyzed mixture will be reduced. The final mechanical properties of the mold will be reached within 7 days.
