SilPruf* SCS2000
silicone sealant & adhesive
Product Description
SilPruf SCS2000 sealant & adhesive
is a dual-purpose silicone and is a
candidate for use in both weathersealing
and structural glazing applications.
SilPruf SCS2000 sealant & adhesive is
a one-component, medium-modulus,
neutral cure silicone useful on a wide
variety of materials in new or remedial
applications. SilPruf SCS2000 sealant &
adhesive is supplied as a paste and upon
cure produces a durable, formed-in-place
silicone rubber joint sealant.
Typical Performance Properties
• Silicone Durability - cured silicone rubber exhibits excellent long
term resistance to natural weathering, including: ultraviolet radiation, high and low temperatures and rain and snow, with negligible
change in elasticity.
• Proven Track Record - Improving global construction projects
since 1974; SilPruf SCS2000 sealant & adhesive demonstrates
superior sealing performance and long-lasting weatherability
in a variety of applications.
• Adhesion - primerless adhesion to many substrates and finishes.
May be considered a candidate for use with numerous construction-related materials, including: glass, polycarbonate, vinyl,
numerous plastics, treated and untreated wood, fluoropolymer
and powder coated paints, conversion-coated and anodized
aluminum, EIFS, brick, terra-cotta, ceramic and porcelain materials, concrete and natural stones. Some finishes or substrates may
require a primer.
• ±50% Movement Capacity - can accommodate 50% movement
in both extension and compression and has excellent recovery
after cycling.
• High Performance Properties - SilPruf’s combination of high
tensile strength, high tear strength and the capacity to absorb
high deformations (elongation) make this product an outstanding
candidate for protective glazing designs and seismic applications.
• Stable Consistency (uncured state) - supplied as a lightweight
paste, the consistency of which remains relatively unchanged over
a wide temperature range. The paste is able to be easily gunned
and tooled under hot and cold conditions.

Typical Performance Properties (continued)
• Thermal Stability (cured state) - once cured, the material
remains elastic over a range of -55°F (-48°C) to 300°F (149°C) and
up to 400°F (204°C) under intermittent short-term exposure.
• Extended Work Life - designed to allow the user sufficient time
for placement and tooling.
• Low Sag or Slump - useful for application to horizontal, vertical
or overhead surfaces.
• Low VOC - significantly lower than the requirements of the U.S.
Green Building Council’s Leadership in Energy and Environmental
Design (L.E.E.D.) program.

Basic Uses
• SilPruf SCS2000 sealant & adhesive is useful as a weatherproofing material when sealing between dissimilar or similar materials
in either new or remedial glazing and sealing applications.
• SilPruf SCS2000 sealant & adhesive is useful as a weatherproofing sealant at window perimeters and punched openings.
• SilPruf SCS2000 sealant & adhesive is useful as a structural
glazing adhesive (project review required).
• SilPruf SCS2000 sealant & adhesive has been sucessfully tested
in protective glazing designs and may be considered a candidate
for such applications.
• SilPruf SCS2000 sealant & adhesive is useful as an adhesive in
panel stiffener applications.
• SilPruf SCS2000 sealant & adhesive is useful for adhering

product line.
Packaging
SilPruf SCS2000 sealant & adhesive is available in 10.1 fl. oz.
(299 ml) plastic caulking cartridges, 20.2 fl.oz. (597 ml) foil sausage
packs, 2 gallon plastic pails (2 gals. / 7.6 L) and 5 gallon plastic
pails (5 gals. / 18.9 L). Plastic cartridges are packaged as 24 units in
cardboard boxes and are dispensed using a single component hand
or air-pressured caulking gun. Cartridges and pails are designed
for convenience in shipping and are easily handled by warehouse
workers and mechanics on scaffolds and staging. Sausage packs
are designed to reduce volume of used containers compared to
conventional sealant cartridges, thereby reducing solid waste. The
use of sausage packs also boosts productivity by cutting typical
reloading time in half.
Colors
SilPruf SCS2000 sealant & adhesive is available in 8 standard colors,
6 special colors, and can be custom colored.

Limitations
SilPruf SCS2000 sealant & adhesive is not recommended:
• For use underwater or in other applications where the product
will be in continuous contact with water.
• For use in food contact applications.
• When painting of the cured sealant is desired (unless appropriate
specialized paint products are used).
• For structural adhesion on bare metals or surfaces subject to
corrosion (i.e., mill aluminum, bare steel, etc.).
SilPruf SCS2000 sealant & adhesive should not be
applied or used:
• In structural glazing applications unless GE - Silicones has
reviewed shop drawings for applicability and has performed
adhesion and compatibility tests on project substrates, spacer
materials and all accompanying accessories. Review and testing is done on a project-by-project basis. No blanket approval
is given by GE - Silicones for structural glazing applications.
Structural glazing industry guidelines (ASTM C1401) suggest that
drawings and details are to be reviewed by all parties involved in
the manufacture of an SSG system and for each building project.
• Under exceedingly hot or cold conditions (see Sealant
Application section for additional information).
• On wet, damp, frozen or contaminated surfaces.
• On excessively basic or acidic substrates.
• In exceedingly large structural cavities (see Sealant Application
section for additional information).
Technical Services
Complete technical information and literature are available
from GE - Silicones. Laboratory facilities and application engineering are available upon request from GE - Silicones.
Precautions
• This material requires atmospheric moisture to cure from paste
to rubber and may not attain its listed final cured rubber properties when used in designs or applications where the silicone is
encapsulated and without access to atmospheric moisture.
• When sealing against natural stones, GE - Silicones recommends
that stain testing be performed prior to use to ascertain the visual acceptability of the sealant-stone combination. GE - Silicones
recommends evaluation of SilPruf NB SCS9000 when sealing to
natural stones.
• Some materials that bleed plasticizers or oils can cause a discoloration on the surface of sealants. When sealing to or over
items such as: rubberized gaskets, bituminous-based materials,
butyl or oil-based products, oily woods, tapes, etc., GE - Silicones
recommends that compatibility testing be performed prior to use
to confirm the suitability of the use of these materials when in
contact with each other.
• Silicone materials are hydrophobic in nature and if inadvertently
over-applied onto adjacent joint surfaces (even if removed immediately), can create a waterproofing effect on some substrate
types when the substrate is wet. See section on Masking.
