Composition: polymer, without silicone
Appearance: clarified liquid
Nonvolatile: 19.0-21.0%
Solvent: aliphatic hydrocarbon solvent/butyl glycolate/ethylene glycol monobutyl ether

Characteristics and use
Inhibit the bubbles produced by wood primer containing zinc stearate and high foaming filler
For high filler wood primer, it has excellent foam inhibition
For hand painted paint, the bubbles caused by high viscosity and poor fluidity can be easily broken
Porous substrates, such as paper, wood, etc., often cause air to remain at the bottom or inside of the coating film during coating, and add VOK ®- Defom 3500 can help the wetting of paint and reduce the residual bubbles
Scope of application
Wood primer
Nitrocellulose lacquer
Polyurethane sealing primer
Wood hand painting
Addition amount and use method
Add 0.1-0.5% to the total amount
Good results can be obtained by adding it before the filler
