SH-120 is a reaction product of amine terminated silicon resin with acrylic ester used as a crosslinker to improve the physical properties and long-term performance of epoxy-siloxane paints and coatings.
APPLICATIONS
SH-120 has been developed primarily for use with liquid epoxy-siloxane resin; it out-performs other epoxy-siloxane based systems by offering the capability to formulate without solvent, at zero VOC.
SPECIAL FEATURES
- Fast film-drying and cure with liquid epoxy-siloxane polymer
- Excellent anti-corrosive resistance
- Excellent adhesion, toughness
- Excellent water and chemical resistance
- Low temperature cure
- Reduces the water absorption
- Improves initial flexibility, thermal resistance.
- Excellent compatibility with epoxy-siloxane resins
- extraordinary weathering resistance
- outstanding gloss retention and low yellowing
- isocyanate-free ambient temperature crosslinking
- suitable for very high-solids coatings
- free of benzylalcohol/alkylphenols

PROCESSING
Information on guide formulations is available upon request.
- All weather-stable pigments can be used.
- SH-120 with Epoxy-Siloxane paints are 2-pack system.
- First pack contains Epoxy-Siloxane resin, pigments, additives,
- Second pack contains SH-120 as hardener.
- Mix both packs thoroughly prior to use.
STORAGE
Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
