DESCRIPTION: Konstrukt™ Join “N” Seal Hybrid Polyurethane Sealant is a high quality, professional and universal low modulus sealant based on hybrid technology that cures under the influence of humidity to form a durable elastic rubber.
It is specially developed for the sealing of construction and expansion joints and joints in pedestrian walkways on most common building materials such as concrete, brick, painted wood, metal, and a variety of plastics.
Once properly cured, the product can be painted over using suitable water-based elastomeric paint.
BENEFITS:
• For interior and exterior use
• Free of isocyanates, solvents, and silicones
• Adheres to the substrate well without the use of primer on most surfaces
• Low modulus
• Cures neutrally
• Low in odor
• Does not shrink over time and is bubble free
• Good UV, weather, and water resistance
• Durable, permanent, and elastic
• High mechanical resistance strength
100% MODULUS (N / sq.mm.): 0.35 MPa
APPLICATION TEMPERATURE: 5 to 40°C
CURING TIME: 2.5 mm / zi
ELONGATION AT BREAK: 350%
*DIN 53504
JOINT MOVEMENT: 25%
SHORE A-HARDNESS: 25 Shore A
*DIN 53505
SKIN FORMATION: 90 minutes
SHELF LIFE:
If unopened and stored between 5°C and 25°C, shelf life is 1 year after production date. Always store product in a cool, dry place.
TEMPERATURE RESISTANCE: 30 to 70°C
TENSILE STRENGTH (N / sq.mm.): 0.5 MPa
PACKAGING: 600 mL sausage

SURFACE PREPARATION
The key to long-term sealant and adhesive performance is proper substrate preparation.
The substrate must be clean, dry, and free of any oils, greases, incompatible sealers, paints or coatings that may interfere with adhesion and good joint performance. Porous surfaces should be cleaned of dust and debris from fabrication or job site dirt before cleaning using a stiff brush or using oil and moisture free compressed air.
Mechanical methods, such as wire brushes or grinders, may be required to remove surface contamination, debris, and failed sealants such as in re-caulking applications.
JOINT DESIGN
A well-designed joint should have a sufficient width so it would be able to take and process the movement of the adjacent building elements.
A general rule is the ratio of joint depth to joint width (with a maximum size of 10 mm) should be 1:1, with a minimum of 5 mm in width and depth. For joints wider than 10 mm, the ratio is 1:2 with a minimum depth of at least 10 mm and a maximum of 15 mm.
APPLICATION AND CURING
Apply Konstrukt™ Join “N” Seal Hybrid Polyurethane Sealant using a professional caulking gun.
CLEANING
Excess sealants should be cleaned off the substrate while it is still uncured using commercial cleaners.
