- Chemical Family
- Polyurethanes (PU)
BJB Enterprises WC-540-AB 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-AB 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.
