Chemical Composition
A copolymer solution of polyether - modified polymethylalkylsiloxane, with the solvent being alkylbenzene/γ - butyrolactone (1/1).
Product Characteristics
- Leveling and Defoaming: It has a defoaming effect, can slightly reduce the surface tension of the coating system, improve fluidity and leveling, and prevent the formation of Benard cells. Unlike most silicone additives, it does not stabilize foams but helps with defoaming.
- Preventing Ghosting: When the same coating is applied repeatedly, it can prevent the appearance of "ghosting" (wipe marks).
- No Impact on Repainting: It does not cause problems of poor re - wettability, nor does it affect the repainting property. It will not lead to issues of loss of wetting and inter - layer adhesion.
- Good Compatibility: In most solvent systems, its compatibility is better than that of BYK - 320. It does not cause turbidity in the varnish layer and can also reduce haze.
- Increasing Slip and Abrasion Resistance: It increases the surface slip, thus improving the scratch resistance and abrasion resistance of the coating.
Typical Physical and Chemical Data
- Non - volatile content is 52%.
Auxiliary Dosage
It accounts for 0.05 - 0.5% of the total formulation dosage.
Usage Method
It can be added at any stage during the production process or added post - production.
Precautions for Storage and Transportation
- When the temperature is below 15°C (60°F), the product may solidify.
- Before use, it needs to be heated to <50°C (<120°F) and mixed thoroughly.
Application Fields
Mainly used in solvent - based coatings, and can also be used in water - based coatings, such as solvent - based automotive coatings and various solvent - based and water - based coating systems.
