WC-540 Polyurethane Elastomer is a two-part, water clear, colorless aliphatic based polyurethane elastomer. It is recommended for use whenever a flexible, permanently transparent elastomer is required. It is UV light and oxidation resistant and can be easily tinted or pigmented to clean bright colors. WC-540 A/B does not contain MOCA, TDI or MDA. In addition to being an excellent castable product, it also functions well as a solvent-free adhesive for bonding various substrates.Recommended for: Lures, Models, Tinted Parts, Impact PartsPotlife & Demould: Work time – 20 mins / Demould time – 8-12 hoursHardness & Type: Shore A45 /-5 Polyurethane Elastomer, 910cpsWC-540 Polyurethane Elastomer will achieve the best results when vacuum degassed. Faster systems such as these do not have the time to release air bubbles sufficiently. Vacuum degassers help remove air from the mixed material prior to pouring into your mould. For the best results, please familiarize yourself with the post-curing schedule outlined in the TDS.
