500-600 Fast-Cure Silicone Paste (2-part)
Novagard® 500-600 is a two-component, 100% alkoxy, neutral-cure silicone sealant that rapidly builds adhesive and elastomeric strength, helping manufacturers move assemblies within minutes of application.
RTV 500-600 is designed for industrial sealing and bonding applications that require fast green strength, reliable adhesion, and long-term environmental durability. Its two-part, variable-ratio chemistry supports faster handling than traditional one-component silicone cure systems while maintaining the weathering resistance, flexibility, and neutral-cure performance expected from Novagard silicone technology.
