ADDITIVES

Copper
Ultra-pure grades film forming additives and modifiers developed to optimize the etching properties of engravers copper:

• Copper-Chem® 13A and 13B: primary film foaming additives for sidewall protection and bevel control
• Copper-Chem® 76 and 77: film modifying secondary additives for stabilizing the primary film forming additives. Minimize decomposition, increase bevel control and smoothness of etch.

Zinc
Film foaming additives for the powderless etching of presensitized zinc plates.

• Velv-Etch®: Film forming additive for building and protecting sidewalls during zinc etching (from the original Phillip A. Hunt Company formula).
• Super Etch®: Our original, tried and true, film forming additives for building and protecting sidewalls during zinc etching.
• Jet Guard: Economic alternative to Revere's Premium additives.

Magnesium
Film foaming additives for the powderless etching of presensitized magnesium plates.

• X5K® Filming Agent: Magnesium film forming additive specially designed for minimal color loss when etching screens and fine lines.
• Rev-Flex® Filming Agent: Our original, high speed, shallow and deep etching magnesium additive specially designed for both regular and flexographic etching.
• X-Flex® Filming Agent: High speed magnesium additive from original Philip A. Hunt formula.
