PROSIL 20 silicone sealant is an acetic one-part moisture-curing high-performance industrial RTV silicone. It is a high-strength 100% silicone designed for general-purpose glazing and sealing applications where long-term reliability is required. It can also be used in the manufacturing of aquariums and has superior chemical, and temperature performance compared to neutral silicone. It is unaffected by high and low temperatures and its superior physical properties are retained over many years of exposure.

ADVANTAGES
PROSIL 20 has excellent adhesion to most common building materials including glass, aluminium, wood, ceramics plastics, and most powder-coated surfaces, but is not recommended for galvanized steel, and concrete, in these cases use PROSIL 10.

• 3-6 minute skin time
• Low Slump
• High-temperature resistance up to 205°C
• Suitable for food applications (Check FDA regs)

APPLICATIONS
PROSIL 20 is ideal in applications such as Automotive gaskets, Industrial assembly, Sealing environmental and refrigerated rooms, sheet metal, skylights, ventilators, and air-conditioning units. Assembly of metal/plastic signs. Weatherproofing, and aquariums.

Approved to BS5889, and is food approved.

PROSIL 20 will have excellent adhesion to many substrates. Admil Adhesives always recommends conducting “Pre-Adhesion” Tests on substrates to ensure adequate bond is achieved.

• Glass
• Aluminium
• Wood
• Ceramics
• Plastics
• Most powder coatings
• Automotive gaskets
• Industrial assembly
• Refrigerated rooms
• Air-conditioning units
• Aquariums

LIMITATIONS
Prosil 20 is not recommended for use: On submerged joints where porous substrates permit water to the bond interface. For use on galvanized steel, concrete, or where acetic acid will attack the substrate In these applications use Prosil 10 Neutral. For certain rubber products where bleeding of plasticiser may occur, check with us if unsure

SURFACE PREPARATION

All surfaces must be clean, dry, sound, and free from dust, oil, rust, or any other contamination.

Metals should be cleaned with a non-oily solvent-soaked clean cloth. Excess solvent should be wiped from the surface with a clean dry cloth. When used on remedial work all existing sealant must be removed. In some instances further cleaning or etching maybe required.
