FAQ

Why is THPS an environmentally friendly fungicide?

THPS can quickly kill bacteria, and then it is oxidized into trimethylol phosphine oxide (THPO), THPO is not a fungicide, and it has no biocidal activity and very low aquatic toxicity.

What are the storage requirements for this product?

Store in a cool, ventilated warehouse. Keep away from fire and heat sources, and keep containers sealed. Should be stored separately from oxidants, acids, and food chemicals.
