DESCRIPTION
Antel
Low Modulus Silicone Sealant is a one part flexible silicone
sealant self priming to most construction materials.
2.
USES
Can
be used for a wide range of applications including sealing
expansion and control joints in precast concrete panels and metal
curtain walls, non structural glazing systems, perimeter sealing
if doors, widow frames and panels.
Its hygienic surface when cured makes it particularly
suitable for use in refrigeration systems.
Suitable
for P V C widow frames and panels.

HEALTH & SAFETY
On
contact, uncured silicone will irritate the eyes.
In case of contact, remove the sealant and flush eyes
thoroughly with water.
If irritation persists seek medical attention.

LIMITATIONS
Not
recommended for joints where abrasion or physical abuse are
encountered.
Do
