Bostik 5CLM is a high performance architectural grade, Low modulus, High Joint Movement silicone. It cures by absorption of atmospheric moisture to form a flexible and durable elastomeric sealant.
Applications:
- All types of building facades restoration and weatherproofing.
- Curtain wall joints
- Marble and Granite joints *(Stain testing must be carried out first before use on any project).
- Expansion and control joints.
- Precast panels
- Concrete panels
- Weather seal / weatherproofing of coated metal and Aluminium composite panels.
- Anodized aluminium
- Coated copper and brass plaques
- Splash backs
- Expansion joints on pavers
Advantages:
- Bostik 5CLM is a non-staining high joint movement silicone sealant suitable for new construction work or remedial applications on facades work, including metal/aluminium composite panels.
- Even on building that have high joint movement Bostik 5CLM places minimum stress on the adhesion bond, between the silicone and the substrate, in working joint application.
- Excellent prime less adhesion too many building substrates. *(Substrate test is always recommended first).
- Excellent elongation movement capabilities +100% / -50%
- Excellent UV stability
- The thixotropic nature of this product ensures that it will not slump in typical construction joints.
- Long life reliability
- Bostik 5CLM has excellent natural ageing stability.
