Product catalog summary
Product Overview: Paraflex 40 is a permanently elastic joint and adhesive sealant designed for both indoor and outdoor use. It is capable of absorbing movements up to 25% and adheres well to most building materials, including slightly moist surfaces and natural stone. The product is free from solvents, isocyanates, and phthalates, and can be painted over with most water and solvent-based paints.
Applications: Suitable for horizontal and vertical connection joints, expansion joints up to 50 mm wide, and for gluing materials such as roof tiles, skirting boards, and stair steps. It is also applicable in construction, industry, and the automobile sector, with excellent adhesion to materials like wood, concrete, metals, and stone. A primer is recommended for absorbent surfaces.
Technical Characteristics: The sealant is based on silyl modified polymers with a pasty viscosity and cures through moisture in the air. It has a skin forming time of 25 minutes and a vulcanization rate of 2.5 - 3 mm after 24 hours. The product has a density of 1.50 g/ml and a shelf life of 12 months when stored in dry conditions between +5°C and +25°C. Cured sealant properties include a Shore A hardness of 40, deformation capability of 25%, and temperature resistance from -40°C to +90°C.
Method of Use: Surfaces must be dry, clean, and free from dust or grease. Use in well-ventilated areas and apply with the supplied nozzle. For adhesive applications, ensure a gap of 3.2 mm between parts to allow for adhesive smoothing. For sealing, use self-adhesive or foam tape to prevent triple-sided bonding. Joint dimensions vary based on width and depth requirements.
Limitations: Not suitable for joints with a width or depth less than 5 mm, or for use on PE, PP, PA, PTFE, and bituminous substrates. It should not be used as a glazing sealant or in contact with the edge seals of insulating glazing and PVB films of safety glass.
Safety and Approvals: Consult the safety data sheet online. The product has CE and SNJF technical approvals, classified as elastomeric sealant type 25E.
