Check the listing for details. Belzona 2100 Base & 2121 Solidifier D&A Hi-Coat Elastomer Protective Coating. Condition: New. Listed at 145.00 USD. These are unopened single containers being sold as sets. I’m willing to separate if you only need the Base. Belzona 2100 Base is the fundamental component (the "base") for Belzona's 2100 Series of Durable & Abrasion Resistant Elastomers, used for flexible, tough rubber-like repairs and coatings on metal and rubber surfaces, offering excellent resistance to wear, impact, and chemicals without heat curing. It's a two-part system that's combined with various solidifiers (like for 2111, 2121, 2131) to create specific grades for building, coating, or fluid application, providing high elasticity and strong adhesion
