SG555

DESCRIPTION

SG555 is designed for use as a weather seal sealant in applications where a high degree of joint movement is anticipated such as in structurally glazed curtainwall or aluminium cladding. It can also be used as a premium grade sealant in general applications such as expansion joints and external perimeter joints.

BASIC USES

SG555 is a single component neutral curing low modulus silicone sealant with good mechanical resistance and adhesion to most porous and non-porous substrates. It has excellent weathering characteristics and will not stain most common substrates. It has a movement accommodation of +/- 50%.
