Features Of Zeneida SC-75LTB Curing Agent

  1. Low-temperature reactive curing capability down to −10 °C, enabling year-round application in cold climates.

  2. Extended pot life of 60–90 minutes at 23 °C, supporting efficient large-area coating and composite lay-up operations.

  3. Excellent compatibility with standard epoxy resins, including DGEBA and novolac types, without requiring pre-drying or solvent adjustment.

  4. Low viscosity (850–1,200 cP at 25 °C) for superior wetting and penetration into fiber reinforcements and porous substrates.

  5. Halogen-free formulation meeting RoHS Directive 2011/65/EU and REACH SVHC compliance requirements.

Typical Applications Of Zeneida SC-75LTB Curing Agent

  1. Wind turbine blade bonding and structural adhesive systems.

  2. Cold-cure aerospace composite tooling and repair matrices.

  3. Industrial flooring and high-performance protective coatings for concrete and steel substrates.

  4. Electrical encapsulation and potting of sensitive electronic components under ambient or sub-ambient conditions.

  5. Marine deck and hull repair compounds requiring low-temperature performance and moisture tolerance.
