Erie Powder / EPC is extremely happy to introduce our latest product offering, our Z1000-G5 Zinc Rich primer.
This primer has been developed by our Research and Development lab to solve the number 1 problem experienced with zinc rich primers – top coat adhesion.
Zinc rich primers have been extensively used in the coatings industry for corrosion control. These products can add incredibly to corrosion resistance of coated steel.
Most all of these products have been based in epoxy in the past, and this has led to problems with top-coat adhesion. Top-coat adhesion can be a huge liability for products out in the field – what happens if the top coat peels off? The customer gets very upset.
This has been extremely difficult to deal with for the coater. Data sheets from suppliers of these epoxy zinc rich products (including ours) state on them that these products should only be “gelled” prior to coating. The reason for this is that if the base coat / zinc rich primer is fully cured, or worse, over-cured, the top coat will often not adhere and delamination is a very real possibility. This is a potential disaster waiting to happen.
Our R&D lab has essentially solved this problem with the zinc rich. While we don’t recommend over-baking this primer, we have produced a new type of zinc rich that has excellent top-coat adhesion. Even when over-baked. Even when significantly over-baked.
This makes this primer far easier to use, and far less prone to disastrous top-coat adhesion problems.
Erie’s Z1000-G5 still has a very high zinc content (60% plus) and still gives excellent corrosion protection. But this product is actually usable in real world situations.
