Spray polyurea
BIOGO-JN
Fast-Setting Spray Polyurea
Two-component · 100% solids elastomer
A fast-reacting plural-component spray membrane for waterproofing, corrosion protection and abrasion-resistant service.
Product overview
Product overview and technical properties.
BIOGO-JN is a two-component, 100% solids, fast-reacting polyurea waterproofing system. The isocyanate-side Part A and amine-side Part B are metered, heated and mixed in the spray gun by dedicated plural-component equipment. The rapid reaction forms a tough, seamless elastomeric membrane for waterproofing, corrosion protection and abrasion-resistant service.
