6. HANDLING PRECAUTIONS
KQ-6512 is a polyol-based product containing, among other substances, a small percentage of tertiary aliphatic amines.
Due to its alkaline nature, KQ-6512 can cause slight to moderate irritation on direct contact with the skin, eyes and mucous membranes, particularly if contact is prolonged.
Splashes in the eyes should be removed immediately by careful flushing with copious amounts of water. If irritation persists, medical attention should be obtained.
Splashes on the skin should be wiped off immediately, after which the contaminated areas
should be thoroughly washed with soap and water. A good barrier cream should then be applied.
Contaminated clothing should be removed immediately to prevent further skin contact and thoroughly cleaned before reuse. The product should be kept away from food, drink.
