Product Description
º CJT-308 is silicone structure sealant of double-component and neutral solidification specially designed for the production of car lamps, which has good structure bonding performance and aging resistant performance. A, B components can solidify and form bonding within a short period after mixing, which can meet the fast-paced requirements of car lamp production.
Product features:
Double component, adjustable solidification speed, fast deep solidification, suitable for factory construction;
Neutral solidification, non-corrosiveness to PC and PP materials;
High modulus, high elasticity, high strength;
Release low molecular weight alcohol during solidification, aging resistant, anti-UV, ozone proof, waterproof;
Excellent high-and-low temperature resistant performance, which will not be fragile, hardened or crazed in -30º Cafter solidification and will not be soft and degraded in +130º C; Always keep good elasticity;
Solidification and maintenance
The whole colloid of JT-308 starts cross-linking reaction after being mixed according to the weight ratio of (11~16): 1 or volume ratio of (8~12): 1. Its surface drying time is related to the mixing ratio of A, B components. After initial binding power is formed (water tightness test can be done after 4 hours), it shall be transferred to the maintenance area. Stress is forbidden before totally solidification. Maximum binding power produced by totally solidification will appear after 3 days.

The above data are only for your reference. Users shall test according to your own requirements before the use. Don't hesitate to contact us should you have any further questions.
It shall not be used if the material surface temperature is lower than 5º C or higher than 45º C.
Avoid long time immediate contact with skin. Go to the doctor at once if it splashes in eyes during the use.
Keep away from fire and children.
