Tecniseal A Data Sheet

Product Description TECNISEAL A is a premium quality, ready-for-use, one-component sealant which reacts with atmospheric moisture at room temperature to form an elastic rubberlike seal. Incorporated fungizide agents prevent surface from mildew-spotting
Typical Applications Sealing of joints in bathrooms, connecting joints, shower cabinets, wash-basins, floor joints etc.For bonding or perimeter sealing of mirrors we recommend B&N Mirror Adhesive.
Properties TECNISEAL A features optimized smoothing and tooling properties. It is resistant to weathering, ageing and UV-radiation, fungicidal, bacteriocidal, resistant to water, rub resistant and has an optimum skin formation time
Application Adhesion surfaces must be clean, dry, sound and free of dust and release agents. Do not use primer on glass and glazed surfaces. Use primer B&N CON FD for porous surfaces. On metals primer B&N CON 790 and on plastics Primer B&N CON FDK may optimize sealant adhesion. Please refer to Primer Chart for recommended surface preparation. For easy tooling use SMOOTHFIX release agent, see EASY TO USE GUIDE. Avoid contact with critical substrates such as bituminous coatings, neoprene, EPDM, butyl etc
