Product Introduction
Momentive SS4004P is a one-component primer specifically formulated
to promote the adhesion of Momentive Performance Materials RTV
silicone rubber adhesive sealants to difficult-to-bond substrates.
Supplied ready-to-use as a solvent solution, it requires no mixing.
SS4004P is particularly effective on metals (e.g., aluminum,
copper, steel, stainless steel, brass, galvanized metals), porous
materials, unglazed ceramics, and wood. Its distinctive bright pink
color provides easy visual verification of uniform coating
application, ensuring consistent and reliable bonding of the
subsequent silicone sealant. It dries at room temperature and
ambient humidity conditions.
Advanced Properties
The special attributes of SS4004P make it ideal for its intended
applications: A 15% solids content indicates a sufficient
concentration of active ingredients to form an effective bonding
layer, while the solvent blend ensures good substrate wetting and
penetration. Its specific gravity of 0.85 indicates it is lighter
than water. The very low flash point (-12°C) clearly classifies it
as a flammable liquid, demanding strict safety protocols for
transportation, storage, and use (refer to SDS). The 30-minute dry
time is standard for industrial processes, offering a reasonable
window for production flow. Crucially, it is specifically optimized
for use with Momentive's Condensation Cure RTV silicones (e.g.,
RTV11-RTV88, RTV500 series, RTV8000 Series), which are its primary
recommended partners. The pink color is a core functional
attribute, directly serving the purpose of visual application
quality control.
Application Scenarios
SS4044P Primer finds wide application in industrial and maintenance
settings where reliable bonding of silicone sealants to metals,
wood, ceramics, etc., is required:
- Industrial Equipment Sealing: Used to seal joints on metal
enclosures like pumps, valves, flanges, and heat exchanger housings
to prevent fluid or gas leaks. E.g., surface preparation on
aluminum or steel flanges in chemical plants or water treatment
facilities before applying sealant. [Note: Inferred from
recommended substrates (metals) and RTV applications].
- Building Maintenance: Surface preparation for sealing joints in
precast concrete panels (porous), metal curtain wall frames, wooden
window frames, or terracotta tiles to enhance long-term adhesion of
silicone sealants. [Note: Inferred from recommended substrates
(porous concrete, metal, wood, unglazed ceramics)].
- Transportation: Used for sealing joints on metal body panels of
trucks/trailers/construction equipment, aluminum radiator or fuel
tank interfaces, and wooden compartment components. [Note: Inferred
from recommended substrates (metal, wood)].
- Electronics/Electrical Potting: Used in scenarios requiring
adhesion of silicone potting compounds to metal enclosures (e.g.,
aluminum junction boxes) or ceramic insulators. [Note: Inferred
from recommended substrates (metal, unglazed ceramic)].
- Web Information Addition - Requires Verification for Specific
Cases: According to some industrial supplier catalogs and forum
discussions, SS4004P is also commonly used for surface preparation
on steel components of bridge expansion joints, seams in steel
structure workshops, and on wood when repairing old windows before
applying silicone sealant. [Sources: Descriptions on platforms like
Grainger, Thomasnet supplier listings, and maintenance forum
discussions often mention metal/wood sealing applications].
