Description Emer-Seal PU 40 is a medium modulus elastomeric joint sealant/adhesive based on polyurethane technology. Emer- Seal PU 40 uses a neutral cure system reacting on exposure to atmospheric moisture. When cured it forms a waterproof and durable seal, which makes it ideal for exterior applications. Technical Support Parchem offer a comprehensive range of high performance, high quality construction products. Parchem also offer a technical support package to specifiers and contractors which includes on-site, technical advice from staff experienced in the construction industry. Design Criteria Emer-Seal PU 40 may be applied in joints between 5 mm and 50 mm wide. All moving joints should be designed to an optimum width to depth ratio of 2:1, with a minimum joint size of 5 mm wide by 8 mm deep for porous surfaces or 5 mm wide by 5 mm deep for non-porous surfaces.
