• Excellent Chemical Resistance
• Resists Fungal Growth
• Weather Resistant
• Excellent Chemical Resistance
• Food Safe Conforms to ISEGA Standards
• No Solvents or Isocyanates
• Paintable
• Unique Flexibility
• Environmentally Compliant
• Works in Wet or Dry Conditions Including Salt Water BONDS ALUMINIUM & WOOD Depending on its moisture, softwoods and hardwoods expand and contract constantly, and some more than others. Aluminium expands and contracts in accordance to temperature. OB1® Construction Sealant & Adhesive will maintain its robust bond when cured from -40°C to +120°C and therefore is able to cope in harsh external weathering conditions and in a refrigerated environment. Its bond has the ability to elongate up to 350%. FOOD SAFE FORMULA OB1® Construction Sealant & Adhesive conforms to ISEGA Standards so it is the perfect solution for use in kitchens and food preparation areas. OB1® Construction Sealant & Adhesive bonds & seals marble, granite and quartz worktops in kitchens plus it’s guaranteed not to attack or stain surfaces. MARINE & POOL SEALANT The original formula makes OB1® Construction Sealant & Adhesive the ideal sealant for under water applications even resistant to saltwater. Its hybrid polymer formulation can be applied under water and retains its initial bond. It also acts as a structural underwater bond in closed-face applications in swimming pools such as floor and wall tiles without the need to drain the pool. PLASTIC TO METAL & STEEL The original solvent free hybrid polymer formula used in OB1® Construction Sealant & Adhesive allows flexible adhesion that can move with the expansion and contraction of metal and steel without etching or burning the surfaces. For polypropylene and polyethylene contact manufactures technical services. ENVIRONMENTALLY SOUND OB1® Construction Sealant & Adhesive contains no solvents or isocyanates resulting in an A+ rating for air quality. It is odourless and kind to the environment as well as being safe for use in residential, domestic and industrial applications. SOLAR PANELS Typically solar panels are installed with mechanical fixings drilled into the roof substrate. They are sealed with silicone mastics which contain a solvent base. The solvent will eventually evaporate causing the mastic to collapse hence the seal/bond line failing. OB1® Construction Sealant & Adhesive does not contain any solvents so it will never crack, shrink or collapse, creating a permanent seal/bond. In addition it has a high resistance to weathering. MIRROR ADHESIVE OB1® Construction Sealant & Adhesive original formulation has no solvents or isocyanates so it will not degrade the back of mirrors. It also has an exceptionally strong initial grab. Depending on size and weight of mirror in most cases OB1® Construction Sealant & Adhesive does not require additional fixings while curing. SUPERIOR FOR BATHROOMS OB1® Construction Sealant & Adhesive features Zero VOC’s (volatile organic compounds) so it cures absolutely solid with no holes – unlike other sealants where bacteria can breed resulting in mould. OB1® Construction Sealant & Adhesive never shrinks or cracks. FIX LEAKING GUTTERS Gutters leak when the EPDM Seal degrades from exposure to the elements. Silicone sealants are often used to repair the seal, but the surface has to be dry first. Solvents within the sealant will evaporate causing it to shrink and collapse on the seal/bond line resulting in failure. OB1® Construction Sealant & Adhesive performs flawlessly even when applied under water, doesn’t contain solvents, so therefore will never shrink or crack. It’s the perfect repair for leaking gutters.
