樂(lè)泰 3751電子組裝/工業(yè)膠水/電子組裝膠水/工業(yè)用膠
技術(shù)服務(wù)熱線：021-51693135 / 021-22818476
樂(lè)泰®3751™ is designed for tacking, bonding,
encapsulating, coating and sealing. The product is solvent free
and cures in seconds when exposed to most types of
ultraviolet lights ranging from low intensity black lights to high
intensity mercury lamps.

TYPICAL CURING PERFORMANCE
樂(lè)泰®3751™ is cured by exposure to ultraviolet light of
sufficient intensity. Surface cure is enhanced by exposure to
UV light in the 220 to 260 nm range. Cure rate and ultimate
depth of cure depend on light intensity, spectral distribution of
the light source, exposure time and light transmittance of the
substrate through which the light must pass.
Storage
Store product in the unopened container in a dry location.
Storage information may be indicated on the product container
labeling.
Optimal Storage: 8 °C to 21 °C. Storage below 8 °C or
greater than 28 °C can adversely affect product properties. 樂(lè)泰®
