One part low modulus neutral cure silicone sealant to ISO11600 F25LM for perimeter pointing, PVCU windows, concrete and lead.
A low modulus silicone sealant, suitable for perimeter sealing of PVC-U frames.
Not recommended for overpainting or for use against natural stone.
Resistant to most alkalis and dilute acids; organic solvents may cause the sealant to swell and loose adhesion, but do not directly dissolve the material.
Very good UV resistance.
Burns, but will not readily ignite, so does not constitute a fire hazard.
Should not cause migratory staining on porous surfaces, but dirt and dust washed into or around joints by rainwater may cause pattern staining. The sealant itself may discolour in contact with rubbers, bituminous or pitch-based DPCs, etc. Contact with some metals may also cause discolouration.
Correctly applied, the sealant should not require maintenance, and has an anticipated life in excess of 25 years.
Health and safety:
Some components are labelled as harmful. Use of this product should be recorded in the project Health and Safety Plan.
+5°C to +50°C.
7–14 days, depending on joint configuration and atmospheric conditions.
A combined joint filler/ bond breaker, such as closed cell foam polyethylene rod, should always be used to ensure that the sealant adheres only to the joint faces and not to the back. Bond breaker tape should be used where the joint has been packed out with fibre-board.
Specify Arbo Primer 2650 for brickwork and concrete. A primer is not required for PVC-U surfaces. Primers are available to suit other substrates – refer to technical literature for details.
