Sikaflex-11 FC Purform – flexible adhesive & sealant

Sikaflex-11 FC Purform

Versatile 1K adhesive and sealant on a Purform® PU base for elastic bonding and joint sealing indoors and outdoors. The following description summarizes the most important manufacturer information from SIKA for selection and processing in a practical manner.

Advantages

• Bonding and sealing with one product
• Permissible total deformation: 25%
• Good mechanical resistance
• Aging and weather resistant
• Excellent adhesion to many common building materials
• Easy to process with a non-sagging adhesive bead
• Flexible, elastic and sandable after curing
• Odorless, solvent-free and very low emission

Applications

• Bonding many components and materials indoors and outdoors
• Vertical and horizontal joints in wood and metal construction
• Wall and floor joints
• HVAC area
• Sealing of gaps and interrupted welds in steel construction to reduce crevice or contact corrosion

Technical Data

• 1-component and moisture-curing
• Purform® polyurethane technology
• Permissible total deformation: 25%
• Packaging: 300 ml cartridge / 600 ml sausage
• VE: 12 cartridges or 20 sausages

Certifications & Tests

• Very low emission
• Very low monomer content; no REACH training required for the safe use of products containing diisocyanates

Processing & Substrate

• Bonding surfaces must be load-bearing, clean and free from oil, grease, dust and loose components.
• Depending on the substrate, stress and weather conditions, cleaners or primers may be required.
• In bonding applications, position the components so that the adhesive layer can fulfill its elastic function.

To Note / Possible Disadvantages

• Not a rigid assembly bonding system: the elastic bond joint must be considered in the design.
• Fully cured material can only be removed mechanically; therefore, working cleanly during processing is particularly important.

FAQ

Which variant is suitable?
Color and packaging are selected separately. For boxed goods, individual units, half VE and full VE are available as options, where provided.

Does it need to be primed?
This depends on Sikaflex-11 FC Purform, the substrate and the stress. The above-mentioned notes and the current SIKA product data sheet are decisive.

Can I use the product outdoors?
Only to the extent that the respective application is approved by SIKA for outdoor use. The substrate, moisture, temperature and load are decisive.

What is important for storage and processing?
Store the packaging closed, dry and within the temperature limits specified by the manufacturer. Observe the product and safety data sheet before processing.
