Chemical resistance:

Sikaflex 252i is resistant to water, sea water and aqueous cleaning agents, temporarily resistant to fuels, mineral oils, vegetable and animal fats and oils, not resistant to organic acids, concentrated mineral acids and caustic solutions or solvents. The information is indicative only.

Fields of application:

Sikaflex 252i is suitable for dynamic loading, structural bonding. Suitable substrates include wood, metals, in particular aluminum and anodized, steel and phosphated, chromated and zinc primers and paint coatings (2-C systems), ceramic materials, plastics. Sikaflex 252i construction adhesive is designed for experienced users. In order to clarify liability and material compatibility tests with original substrates are recommended below the respective production conditions.

Processing:

Application temperature: + 10ºC to + 40ºC.
Attaching method: spraying with manual pressing gun, compressed air gun or caulking gun.
Cleaning: with white spirit before curing, then with cleaner or removed mechanically.
Smoothing: smoothing and trowel before skinning.

Notes:

UntergrundvorbereitungDie Surfaces must be clean, dry, dust and grease. Information for the preparation of material surfaces can be found in the Sika Primer Chart for component Polyurethane.VerarbeitungDie processing temperature must not exceed 10 ° C or above 35 ° C does not exceed. The optimum temperature for substrate and adhesive is between 15 ° C and 25 ° C. In cartridges application we recommend the use of a piston rod pneumatic or cordless gun. For uniform adhesive layer thickness we recommend Sikaflex 252i construction adhesive in the form of a triangular bead aufzutragen.AbglättenDas smoothing must be within the skin time of the adhesive occur. For smoothing we recommend Abglättmittel.EntfernungNicht Uncured Sikaflex 252i can be removed from tools and equipment with Sika Remover 208. Cured material can only be mechanically removed. Hands / skin should be cleaned immediately with Sika Hand Clean or a suitable industrial hand cleaner and water. Do not use solvents! ÜberlackierenNach skin forms Sikaflex 252i can be painted over. The paint compatibility must be verified by preliminary tests. Baked enamels should not be applied only to fully cured Sikaflex 252i. Suitable generally are paints 1KPUR- and 2K acrylate base. Oil based paints are unsuitable. It should be understood that the hardness and film thickness of the paint affect the adhesive in its expansion and can lead to cracking in the paint.

Substrate condition:

Surfaces must be sound, solid, clean, dry and free of oil, grease and loose particles, laitance, paints, water repellents and anti-graffiti coatings.

Storage:

12 months from date of manufacture in cool and dry conditions in undamaged original packaging at temperatures between + 15 ° C and + 25 ° C.

Delivery Form:

Cartridge 300ml

Color:

black, white, gray
