Areas of application

ACRONAL® 4420 is mainly used for water-repellent coatings on account of its low emulsifier content and the hydrophobicity of the film that it forms. It can also be used to bond nonwovens. It is a particularly appropriate choice for bonding wet-laid nonwovens that are made from inorganic fibers.

Processing

ACRONAL® 4420 can be applied by all conventional wet impregnation, spraying and coating techniques.

Customers should carry out their own trials when developing products based on ACRONAL® 4420. Its compatibility with other ingredients, its adhesion on different fibers and its stability in storage, etc., are affected by a variety of factors that are too numerous for us to take into account in our own trials
