Recommendations for Flattening Additive 4/5

[DCSP John]

Any leads on who makes a good flattening agent?
We just used up the last of our the Union Flattener.
Can't seem to locate any more.

We have tried some minimal puff additive to ward off gloss, and have some
Union Suede additive.. but are still big fans of the Union Flattener...

Thanks.

With International Coatings, their 222 additive is both for flattening and suede in different quantity addition.
Interesting that Union has two different ones.
