特價原裝漢高樂泰365厭氧膠 紫外線密封劑

價格50元代表面議

產品簡介
樂泰®產品365 是一種單組分，中等粘度的厭氧型
紫外線固化膠粘劑/密封劑。厭氧固化時需使用活
化劑707 或加熱。
典型用途
本產品用于電路接頭的密或封裝以提高其耐候
性。由于本產品綜合了紫外線固化和厭氧固化兩
者的優(yōu)點，因此比產品363 具有更深的封裝性
能，建議用于消除應變和防干擾的場合。

PRODUCT DEscriptION
LOCTITE® Product 365 is a single component, medium
viscosity adhesive/sealant with anaerobic and ultra violet
radiation cure systems.
TYPICAL APPLICATIONS
This product is used to seal or encapsulate electrical terminals
against atmospheric conditions. The combination ultra violet
and anaerobic cure system permits deeper potting than
Product 363 and is also recommended for strain relief and
tamperproofing.

TYPICAL CURING PERFORMANCE
This product is cured when exposed to UV radiation of 365nm.
To obtain a full cure on surfaces exposed to air, radiation at
250nm is also required. The speed of cure will depend on the
UV intensity as measured at the product surface. Typical cure
condition is 20 - 30 seconds at 100mW/cm² using a medium
pressure, quartz envelope, mercury vapor UV lamp.
NOTE: UV intensities where quoted are measured at
365nm using an OAI 206 UV meter.

Tensile strength is measured using a test method based on
ASTM D2095. A metal pin (Ø12.7mm x 38mm) is bonded at
one end to 6mm thick Pilkington float glass (50mm x 50mm).
The pin is then pulled axially from the glass.

GENERAL INFORMATION
This product is not recommended for use in pure oxygen
and/or oxygen rich systems and should not be selected as
a sealant for chlorine or other strong oxidising materials.

This product is UV sensitive. Exposure to daylight, UV light
and artificial lighting should be kept to a minimum during
storage and handling. Product should be dispensed from
applicators with black feed lines. For best performance bond
surfaces should be clean and free from grease.
UV light cure rate is dependent on lamp intensity, distance
from light source, depth of cure needed or bondline gap and
light transmittance of the substrate through which the radiation
must pass.
Recommended intensity for cure in bondline situation is
5mW/cm2 minimum (measured at the bondline) with an
exposure time of 4-5 times the fixture time at this same
intensity. For dry curing of exposed surfaces higher intensity
UV is required (100W/cm2 minimum).
Cooling should be provided for temperature sensitive substrate
such as thermoplastics. Plastic grades should be checked for
risk of stress cracking when exposed to liquid adhesive.
Excess adhesive can be wiped away with organic solvent.
Bonds should be allowed to cool before subjecting to any
service loads.

Storage
Products shall be ideally stored in a cool, dry location in
unopened containers at a temperature between 8°-21°C (46°-
70°F) unless otherwise labelled. The shelf-life period for a
250ml container is 12 months based upon date of
manufacture. To prevent contamination of unused product,
do not return any material to its original container.
