LOCTITE SI 594
Harmonization Code : 3208.20.90 | Paints and varnishes that are dispersed or dissolved in a non aqueous medium
Main features
- 24-Hour Full Cure
- At Least 300 g/min Extrusion Rate
- At Least 275% Cured Elongation
Product Description
LOCTITE SI 594 is a one-component white acetoxy RTV silicone adhesive/sealant for potting, coating, sealing, and general industrial bonding. The thixotropic paste has a specific gravity of 1.01 at 25 deg C and an extrusion rate of at least 300 g/min under the specified Semco-cartridge test. Moisture exposure produces a tack-free surface in about 2 hours, and full cure is stated at 24 hours, with cure time dependent on temperature, humidity, and gap. After one week at 22 deg C, cured elongation is at least 275% and tensile strength is at least 0.8 N/mm2.
Key features
- Full-Cure Schedule: Reaches full cure in 24 hours; actual cure time varies with temperature, humidity, and gap.
- Controlled Extrusion: Semco-cartridge extrusion is at least 300 g/min at 0.63 MPa for 15 seconds at 25 deg C.
- Cured Flexibility: Elongation is at least 275% by ISO 37 after one week at 22 deg C.
Applications
Potting; coating; sealing; general industrial bonding.
