3C SEALANTS POLYMER SEALANT (POLYSULPHIDE SEALANT ALTERNATIVE) 380ML
3C SEALANTS POLYMER is a professional trade grade, polysulphide sealant alternative, based on state-of-the-art hybrid polymer technology. It’s particularly high elasticity and paintability makes it the ideal choice for all modern and retro glazing and cladding applications or indeed any other connecting joints that are notorious for high movement.
Polysulphide sealant (also occassionally spelt polysulfide sealant) was traditionally used for many external (and sometimes internal) joint sealing tasks such as perimeter sealing of window and door frames, expansion joints in brickwork etc. and any other applications where highly elastic movement was necessary, 3C Polymer Sealant perfectly replaces this old technology and does a more efficient and longer-lasting job!
Tried and thoroughly tested for adhesion to a multitude of common construction materials, 3C Polymer Sealant seals perfectly between differing substrates (such as connecting joints consisting of brickwork, UPVC and timber for instance) offering an over-paintable cure that will stand the test of time without the shrinkage and splitting/cracking associated with other sealants.

Although silicones are widely used for practically all circumstances of joint sealing, the argument for hybrid polymer sealants has grown significantly over the past decade with many professionals preferring the new technology over silicone sealants.

BENEFITS:
- Excellent resistance to weathering, ageing and UV
- Easily tooled to a high standard finish
- Suitable for both internal & external use
- Great elastic movement for sealing movement joints
- Will not shrink or crack after time
- Overpaintable (takes nearly all water-based paints & stains when cured) It can also be painted with oil based paints, but full cure is recommended prior to application.
- Long shelf life (2 x years)
- Fantastic all-round, long life performance
RECOMMENDED FOR:
- Sealing between different substrates (eg. metal frame into a brickwork surround)
- For sealing all inside & outside construction connections where high movement occurs
- Adheres perfectly to all woods, metals, plastics (such as uPVC), brickwork, plaster, composites & more
- Seals that subsequently require painting over (either; after cured application or in the future)
- Applications where old-fashioned Polysulphide has been specified
- Weather sealing of new frames and cladding (as well as remedial or repair works)
