A low modulus silicone sealant, suitable for structural joints in light cladding.

Not recommended for overpainting, use against natural stone or with laminated glass.

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.

Burns, but will not readily ignite; it does not therefore constitute a fire hazard.

Should not cause migratory staining on porous surfaces such as reconstituted stone, 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.

Very good UV resistance.

Correctly applied, the sealant should not require maintenance, and has an anticipated life in excess of 25 years.
