Guinea What are the Free of silicone defoamers for paints(1)

carbon

raw

agent

Guinea Selection of antifoaming agents for different applications:

viscosity-reducing

Flat coating

foam

Features: Low viscosity, low defoaming pressure

silver

Recommendation: Mineral oils or mineral oil modified polyethers

Elastic coating

Features: High viscosity, high Free of silicone defoamers pressure

Recommendation: Polyether modified silicone

Surface coating and film covering adhesive

Recommendation: Polyethers, which can effectively prevent surface defects and have a small impact on gloss

Water in Water Colorful

Features: More surfactants, stable foam

Guinea Recommendation: Use polyethers or mineral oil to modify polyethers

Precautions for use of paint Free of silicone defoamers:

Before use, stir thoroughly and mix evenly; Adding the paint while stirring; Before use, it is generally not diluted with water; The dosage should be appropriate. Excessive dosage can cause shrinkage, edge shrinkage, poor brushing performance, and other problems; Too little dosage leads to poor defoaming effect; Add it in two stages, namely, add it in the grinding stage and the paint mixing stage, generally accounting for half of the total amount each time. Use defoaming agents with good foam suppression effect in the grinding stage, and use defoaming agents with good foam breaking effect in the paint mixing stage
