乐泰® SI 5089™ is used for gasketing and sealing applications. Upon exposure to sufficient UV light and/or atmospheric moisture, this product cures to form a durable, flexible rubber sealant. Typical applications include gasketing/sealing of enclosures that require a rapid curing, post-applied sealant that facilitates immediate on-part inspection. The thixotropic nature of 乐泰® SI 5089™ reduces the migration of liquid product after application to the substrate.
TYPICAL PROPERTIES OF UNCURED MATERIAL
Specific Gravity @ 25 °C 1.05
Flash Point - See SDS
Viscosity, Brookfield - RVT, 25 °C, mPa•s (cP):
Spindle 6, speed 2.5 rpm, 80,000 to 125,000LMS
Solids/Non-Volatile Content, % ≥95
TYPICAL CURING PERFORMANCE
Normal processing conditions will include exposure to sufficient UV light irradiance to effectively cure the material. Surface and/or atmospheric moisture will promote the cure of material in shadowed regions. Although functional strength is developed almost instantly due to the UV curing nature of
乐泰® SI 5089™, increased cure properties are developed during 72 hours at ambient conditions.
Depth of Cure
Depth of cure, mm:
72 hours @ 22 °C 0.58
30 seconds @ 70 mW/cm2, measured @ 365 nm 1.52
60 seconds @ 70 mW/cm2, measured @ 365 nm 1.78
30 seconds @ 200 mW/cm2, measured @ 365 nm ≥1.3LMS
60 seconds @ 200 mW/cm2, measured @ 365 nm 2.03
Skin Over Time
Skin over time is the time the surface of the adhesive forms a
skin upon exposure to atmospheric moisture at 25 ± 2 °C, 50 ±
5% RH.
Skin Over Time, minutes:
Cured @ 22 °C 90
Skin Over Time, seconds:
Cured @ 70 mW/cm2, measured @ 365nm 5 to 10
Cured @ 200 mW/cm2, measured @ 365nm <5
