Sikaflex-11 FC Purform - Multifunctional PU adhesive - Sika

Sikaflex-11 FC Purform - Multifunctional PU adhesive - Sika

Sikaflex-11 FC Purform is a single-component glue and sealant , hardening under the influence of humidity.

The product is used for bonding as well as filling joints indoors and outdoors.
It has good and durable adhesion to most building materials.

Features

• Movement capability of ±25%
• Easy to apply and no sag
• Sticks well to most building materials
• Good mechanical and weather resistance
• Very low monomer content
• No need for training on the safe use of diisocyanates (REACH)
• Glue/sealant with CE marking

Application areas

A glue for bonding building components and materials such as:

• Concrete.
• Masonry.
• Reconstituted or cast stone.
• Ceramic.
• Drink.
• Metal.
• Glass.

A joint sealant for making vertical and horizontal joints.

Application

Procedure for gluing

1. After necessary media preparation, prepare the end of the cartridge/packaging before or after inserting it into the gun, then attach the nozzle.
2. Apply in triangular beads, strips or dots a few centimeters apart.
3. Use only manual pressure to position the elements to be glued and this before a skin forms on the glue.
4. A badly positioned element can be easily removed and then repositioned during the first minutes after application.
5. If necessary, temporarily use tape, shims, or supports to hold the assembled components together as the glue begins to harden.
   Fresh, uncured glue remaining on the surface should be removed immediately.
   Final strength will be achieved after Sikaflex-11 FC Purform has fully cured, ie. after 24 to 48 hours at 23°C, depending on the environmental conditions and the thickness of the adhesive layer.

Grouting procedure

1. Prepare the end of the cartridge/packaging before or after inserting it into the gun, then attach the nozzle.
2. Extrude Sikaflex-11 FC Purform into the joint ensuring that it comes into full contact with the sides of the joint and avoiding any inclusion of air bubbles.

Consumption

Grouting:
Approximate consumption for floor joints

The minimum joint width for joints around windows is 10mm.

The consumption depends on the roughness and the degree of absorption of the support.
These values are theoretical and do not take into account higher consumption due to surface porosity and profile, level differences and product losses, etc.

Conditioning

• 300ml cartridge.
• 600ml bag.
