CURE TIME
As exposed to air, SV995 begins to cure inward from surface. Its
tack free time is about 50
minutes; the full and optimal adhesion depends on the sealant
depth.
SPECIFICATIONS
SV995 is designed to meet or even exceed the requirements of:
Chinese national specification GB/T 14683-2003 20HM
STORAGE AND SHELF LIFE
GB557 should be stored at or below 27℃ in original unopened
containers. It has a shelf life of
12 months from the date of manufacture.
LIMITATIONS
SV995 should not be applied:
For structural glazing
For weather seal for curtain walls
To underground joints
To joints with high movement
To the materials that bleed oils , plasticizers or solvents, such
as impregnated wood ,or
unvulcanized resin
In totally confined spaces as sealant requires atmospheric
moisture for cure
To frost laden or damp surfaces
For continuous water immersion
When surface temperature below 4℃ or over 50℃
HOW TO USE
Surface Preparation
Clean all joints removing all foreign matter and contaminants such
as oil, grease, dust, water, frost,
old sealants, surface dirt, or glazing compounds and protective
coatings.
Application Method
Mask areas adjacent to joints to ensure neat sealant lines. Apply
SV995 in a continuous operation
using dispensing guns. Before a skin forms, tool the sealant with
light pressure to spread the
sealant against the
joint surfaces. Remove masking tape as soon as the bead is tooled.
TECHNICAL SERVICES
Complete technical information and literature, adhesion testing,
and compatibility testing are
available from Guibao.
SAFETY INFORMATION
SV995 is a chemical product, not edible, no implantation into
body and should be kept
away from children.
Cured silicone rubber can be handled without any risk to health.
Should uncured silicone sealant contact with eyes, rinse
thoroughly with water and seek
medical treatment if irritation persists.
Avoid prolonged exposure of skin to uncured silicone sealant.
Good ventilation is necessary for work and cure places.
