Formalin is a water-based solution of formaldehyde gas, typically containing about 37-40%
formaldehyde by weight, along with a small amount of stabilizer like methanol to prevent
polymerization.
It is widely used as a disinfectant, preservative, and in the production of
resins like urea-formaldehyde and phenol-formaldehyde. Formalin is also employed in medical and
biological fields for preserving tissue specimens due to its ability to inactivate bacteria and
fungi.
Application Method:
It is used in production of aminoplast resins such as urea
formaldehyde adhesives, UF and MUF
impregnation resins. It is used as anti-caking agent in the process of urea production.
As an antiseptic in hospitals, cattle breeding centers,
contaminated public places, sugar industries and sanitary detergents.
Storage Life:
6 months at 35 – 45 ºC
Packaging:
20-liter HDPE plastic drums, 20 – 22 MT stainless steel tanks and ISO tank containers.
