BYK-Catalyst-470
Solution of an amine salt of Dodecylbenzene Sulfonic Acid (DDBSA)
Blocked acid catalyst for solvent-based and aqueous coating systems.
The additive accelerates the cross-linking of amino resins with resins containing hydroxyl groups.
Especially low reactive melamine formaldehyde resins of HMMM type need an accelerator to lower curing temperature or to reduce baking time.
The additive permits the production of stable one-pack systems and provides consistent durability, excellent package stability and superb film properties.
It has no negative influence on conductivity or wrinkling and does not adversely affect gloss and haze.
BYK-Catalyst 470 provides excellent hardness at baking temperatures, depending on the system, starting from 190'F to 210'F.
In comparison to pure DDBSA, it displays considerably lower viscosity increase on storage (which can extend shelf life 6-10 times).
It also exhibits little influence on the electrical resistance, and is therefore very suitable for coatings which are applied electrostatically.
BYK-Catalyst 470 is only availabe in the North American market.
