OB1 is a food safe formula and conforms to ISEGA, so it is ideal for use in kitchens and food preparation areas.  It can be used on granite, marble and quartz worktops and sinks.  it is guaranteed not to attack or stain surfaces.

OB1 has the ability to bond to almost all surfaces including metals, lead, carbon fibre, fiberglass and GRP.  Also plastics, glass and ceramics.  For polypropylene and polyethylene contact manufactures technical services.

The original solvent free hybrid polymer formula used in OB1 allows flexible adhesion that can move with the expansion and contraction of metal and steel without etching or burning the surfaces.  With its unique flexibility it expands and contracts constantly, with the ability to elongate upto 350%.  It will maintain its bond when cured between -40°C and +120°C and therefore is able to cope with harsh external weather conditions or in a refrigerated environment.  OB1 will also withstand vibration.

OB1 does not contain solvents or Isocyanates so it will never crack, shrink or collapse, creating a permanent seal/bond.  Silicone mastics which contain a solvent base, which will eventually evaporate causing the mastic to collapse hence the seal/bond line failing.  In addition it has a high resistance to weathering.  With its hybrid polymer formulation it can 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.  It also resists salt water.  This also makes it ideal for guttering repairs and garden repairs to materials such as concrete, terracotta and pond ornaments.

Ideal for bathrooms OB1 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 never shrinks or cracks.  It resists fungal growth and has excellent chemical resistance.

OB1 is a universal sealant, adhesive and filler which can be painted, making it the ideal for most repairs.

OB1 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.

Outdoor uses – Guttering, lead flashing, roof tile repairs, garden repairs, solar panels, garden and pond ornaments, swimming pools, cracked concrete repairs and many more.
