Used as vulcanizing agent and cross-linking agent for room temperature curing silicone rubber. Tetrabutylketoxime silane is often mixed with methyltributylketoxime silane, which can greatly improve the surface drying speed, avoid surface cracks, improve tensile strength and other properties of deketoxime type room temperature curing silicone rubber. Instead of vinyl tributyl oxime silane, tetrabutyl ketone oxime silane can avoid the disadvantage of vinyl tributyl oxime silane which is easy to turn yellow. By using tetrabutylketoxime silane, it is also possible to use no catalyst organotin, which has applicability in places where organotin cannot be used.
Packing
25KG/plastic drum, 190KG/plastic drum or plastic-lined iron drum, 950KG/IBC
Storage and transportation
1. Store in a cool, ventilated warehouse. Keep away from fire and heat source. It should be stored separately from oxidizers and edible chemicals, and should not be mixed for storage or transportation. The storage area should be equipped with suitable facilities to shelter spills.
2. Keep the lid of the drum tightly closed, keep it upright and forbid mechanical damage. Do not expose to wet air and do not recycle drums.
3. The packaging should be complete and loaded securely when starting transportation. During transportation, ensure that the container does not leak, collapse, fall or damage. During transportation, it should be protected from exposure to sun and rain and high temperature.
