Applications & Uses

Coatings:
ADD-2040 has a very wide compatibility, which makes it extremely suitable for use in clear coatings. It is recommended in the following application systems:
• Vinyl, acrylate and chlorinated polymers
• 2-K PU and epoxy coatings
• Industrial and decorative finishes based on medium- or long-oil alkyd resins
• Stoving systems based on alkyd/melamine
• Epoxy floorings
To prevent foaming, ADD-2040 can be added prior to processing. If it is added to the finished product, care must be taken to ensure uniform distribution.
