FILCO polyurethane film formers, non-reactive anionic

Two anionic polyurethane dispersions at 60 percent solids. Aliphatic, hydrazine free, non-yellowing and moisture resistant, with a polyether option for hydrolysis resistance.

Home Products COIM FILCO polyurethane film formers, non-reactive anionic

This is the anionic pair. Same aliphatic, hydrazine free backbone as the larger non-ionic family, stabilized a different way, and both grades run at 60 percent solids where most of the non-ionic family sits at 40 to 45.

Ionic character decides what else the size bath can carry. An anionic dispersion is stabilized by charge, so it is sensitive to what it is mixed with in a way a non-ionic dispersion is not.

Two grades are published, and they split on polyol. FILCO 7810 is the all-purpose polyester-polyol at a minus 31 degree F Tg and 600 nm. FILCO 108 uses a polyether and polycarbonate polyol for increased hydrolysis resistance, at 900 nm.

COIM's stated characteristics for the pair are non-yellowing films and resistance to moisture. Both come from the aliphatic backbone, which is what the whole polyurethane side of the FILCO range is built on.

It is also written as anionic polyurethane dispersion, PUD film former, and high solids polyurethane dispersion.

Applications

Lines limited on water removal

Both grades at 60 percent solids, against 40 to 45 percent across most of the non-ionic family.

Wet and humid service

FILCO 108, polyether and polycarbonate polyol, published for increased hydrolysis resistance.

Parts judged on appearance

Non-yellowing films from the aliphatic backbone, on both grades.

Anionic size systems

Where the rest of the bath is anionic and a non-ionic film former would be the odd component.

It is specified where the formulation needs 60 percent solids on both grades, the highest in the polyurethane range, aliphatic and non-yellowing, hydrazine free, and a hydrolysis resistant option in FILCO 108.

Handling and dispersion

Applied at the forming line in a sizing bath. Anionic stabilization is sensitive to what shares the bath, so confirm compatibility before changing another component.

At 60 percent solids these carry more film former per unit of water than the non-ionic grades, which matters where drying capacity limits line speed.

Only two grades are published here. If neither fits, the non-ionic family carries seven and is the first place to look.

Packaging, storage, and regulatory status

Package sizes: Made to order in the pack size the line needs. Tell us the volume and we will confirm..

Storage: Store in the original sealed container, protected from frost and from direct sun. Freezing destroys a water based dispersion permanently. Confirm the shelf life on the current data sheet for your grade.

Read the safety data sheet before handling. We supply the current SDS with every grade.

Frequently asked questions

What does anionic change compared with the non-ionic family?

How the dispersion is held stable. An anionic dispersion is stabilized by charge, which makes it sensitive to what shares the bath, particularly to cationic components and to changes in ionic strength. Non-ionic dispersions are more tolerant of mixed formulations. Know which one you have before you change another component.

Why are both grades at 60 percent solids?

It is the highest solids content in the FILCO polyurethane range, against 40 to 45 percent across most of the non-ionic family. Where drying capacity is what limits line speed, more solids per pass is the practical benefit.

Which grade for humid or wet service?

FILCO 108. It uses a polyether and polycarbonate polyol and COIM publishes it for increased hydrolysis resistance. FILCO 7810 is a polyester polyol, which is the chemistry that hydrolyzes in sustained wet heat.

Only two grades. Where do I go if neither works?

The non-reactive non-ionic family, which carries seven grades across four polyols, or the reactive family if the process reaches the unblocking temperature. Tell us the matrix and the conditions and we will point you at the right family first.

Can I get a sample and a data sheet?

Yes. Tell us the matrix polymer, the process and the service conditions and we will send the current technical data sheet with the matching safety data sheet, and arrange sample material.

Can I get the TDS and SDS for FILCO polyurethane film formers, non-reactive anionic?

Yes. We send the Technical Data Sheet (TDS) and Safety Data Sheet (SDS) on request, in the manufacturer's current revision. Use Request TDS or SDS above and tell us what your qualification review needs.
