Description

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 exposure.

ADVANTAGES
PROSIL 20 has excellent adhesion to most common building materials including : glass, aluminum, , 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. Weather proofing, and aquariums.

Approved to BS5889, and is food approved.

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, such as PROSIL CLEANER 1. 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.
