Silpak RU-575 Water Clear Polyurethane Plastic
Categories:	Polymer; Thermoset; Rubber or Thermoset Elastomer (TSE)
Material Notes:	Silpak RU-575 is an easy 1A:1B, by volume, system that cures quickly to a water clear, strong, plastic. It develops hardness and can be demolded rather quickly. It has a high heat deflection temperature which is useful in certain prototyping applications. This product has low viscosity and a long pot-life which facilitates easy mixing, excellent detail penetration, and easy degassing through vacuum or pressure casting techniques for bubble-free castings. Features: Crystal clear Resistance to yellowing with UV exposure Can be machined, drilled, and sanded Long working time Low shrinkage upon cure Reproduces fine detail Tough and hard but not brittle Applications: Prototypes Lenses Model Windows Clear injection plastic parts Decorative objects Encapsulation Information provided by Silpak a division of Polytek Development Corp.
