SH-182 is a reactive amine terminated polysiloxane with highly branched carboxylic acid combine in one molecule. This curing agent used as a crosslinker to improve the physical properties and long-term performance of epoxy-siloxane paints and coatings.
APPLICATIONS
SH-182 has been developed primarily for use with liquid epoxy-siloxane resin, it out-performs other epoxy-siloxane based systems.
SPECIAL FEATURES
- Fast film-drying and cure with liquid epoxy-siloxane polymer
- Excellent anti-corrosive resistance
- Excellent adhesion, toughness
- Excellent acid and alkali resistance
- Low temperature cure
- Reduces the water absorption
- Very low Absorption/Desorption for cargo tank coatings
- Improves initial flexibility, thermal resistance.
- Excellent compatibility with epoxy-siloxane resins
- outstanding gloss retention and low yellowing
- superior outdoor durability
- suitable for very high-solids coatings
- easy-to-clean/anti-graffiti effect
- Hydrophobic
- Low color
