EG 91

Epoxy-polyurethane two-component, plastic, elastomeric sealant

Code: PRS.0034

Components: 2

Appearance: Liquid

Epoxy-polyurethane two-component elastoplastic sealant, for joints subject to traffic, where Shore A Hardness Scale = 65. The elongation-at-break is 70%. To be applied with a trowel or extruded into the suitably-taped sections of the joint (to protect adjacent surfaces). Resistant to contact with hydrocarbons (gasoline and diesel fuel).

Use fields

Horizontal sealing of joints in industrial flooring, even in the presence of chemical attacks and stresses from average-heavy traffic. Vertical sealing of joints in concrete works and products.

Preparation of supports

The application and containment surfaces (joint walls) should be clean, dry, conveniently prepared and adequately resistant: free from dust, grease, soiling, crumbling and/or non-adhering parts and dry. The application surfaces must also be preliminarily treated with PROTECH FLEX PRIMER.

Use method

Add component B to component A taking care to pick up all the material contained in the packs, mix thoroughly with a mixer at a low number of revolutions, until a perfectly homogeneous mix is obtained; add the required load amount (component C) continue to mix until a perfectly homogeneous mixture is obtained, indicated by the uniform colour of the mixture. Apply the product mixed by trowelling or with extrusion guns.
Do not apply with temperatures below + 5°C or higher than + 35°C and in the presence of surface stagnant water.
