A one part, low modulus, neutral cure silicone sealant.
Application
Suitable for perimeter pointing, PVCU windows, concrete and lead.
Description
A one-part, low modulus, neutral cure silicone sealant.
Features and benefits:
- 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 lose adhesion, but do not directly dissolve the material.
- Very good UV resistance.
- Available in nine standard colours.
- 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.
- 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.
