Typical Application Surfaces: Sealing expansion joints
• One-part, neutral-curing, low modulus silicone sealant with good indoors and outdoors, such
adhesion for the construction and glazing industry. as door, wall, floor, ceiling
• Cures at room temperature under the action of atmospheric moisture to and window sill joints, as
give a permanently flexible silicone rubber. well as eaves and gutters.
• Excellent primerless adhesion to many substrates, i.e. glass, ceramics,
enamel, glazed and clinker tiles; metals (aluminium, steel, zinc or
copper); wood (impregnated, varnished or painted), and many
plastics.
• The adhesion can be improved in many cases by pretreatment of the
