Copsaflex 11-C
Polyurethane elastic sealant for joints
Documento sin título
Description
COPSAFLEX 11-C is a one-component sealant of paste like consistency based on polyurethane which polymerizes once in contact with the ambient humidity.
COPSAFLEX 11-C adheres to practically all construction materials. It is totally waterproof and exhibits high mechanical performance as well as excellent performance against chemically aggressive products.
COPSAFLEX 11-C meets the SNJF Norms, elastomeric 1st grade and UNE 53.622-89, B-1 Class.

- Joint factor: Relation width/depth (w/d):
- w < 15 mm: w/d= 1/1.
- 15 < w < 25 mm: w/d = 2/1.
- Max. acceptable movement: 25%.
- Chemical resistance: waterproof.
Application procedure
Preparation of the joint: The interior of the joint to seal should be free from humidity, friable material, grout or residual material.
Place a cord of polyethylene, with a section bigger than that of the joint, at the bottom of the joint, at a suitable depth, so that it fits well in it. The section to fill should be a function of the joint width.
Priming: In general, priming is not necessary. If the substrate is very porous, COPSAFLEX 11- C PRIMER should be used.
Application: Pierce the cartridge tip and screw the plastic nozzle, cut at bezel (45ª), to suit the width of the required cord. Place the cartridge into a gun, either by hand or pneumatically, keeping the gun at a convenient distance away from the joint, to avoid air blockage in the sealing.
Joints, smaller than 5 mm, should be opened. For joints wider than 1cm we recommend placing a cord at each edge and another one at the bottom.
Tools cleaning: Tools should be cleaned with COPSA Cleaning Solvent, immediately after use. Once the product hardens, it can only be cleaned by mechanical means only.
Recommended for
- Joints between carpentry work and factory repairs.
- Pavement joints.
- Cracks filling.
- Prefabricated material sealing.
- Structural joints subject to big movements and dilatation.
- Joints between metal elements (steel, aluminium, lead, etc.) once free from grease.
- Elastic sealing and construction material fixing in general.
Special precautions
COPSAFLEX 11- C does not resist UV rays. The lighter colours undergo a colour modification. This does not affect the resistance of the product.
COPSAFLEX 11- C contains isocyanate.
Avoid eye and skin contact. In case of such contact, wash thoroughly with water and see a doctor. If the product is inhaled, see a doctor immediately. Do not provoke vomit.
Use gloves and goggles during the preparation and the application of the material.
Do not discharge to sewer, rivers or canals.
Empty packaging must be disposed of according to the local legal environmental regulations.
