Liquid rheological auxiliary agent for solvent-type and solvent-free system is also suitable for PVC plastic sol and natural curing resin system. It can form a high touch change effect, and therefore improve the anti-settlement and anti-fluid hanging performance. Can be added after.
on-product information
chemical composition
Modified polyurea solution.
Typical objecochemical data
The data presented on this data page are only typical values, not technical indicators of the product.
Appearance is yellow to brown in liquid
Density (23℃) 1.02-1.12 g / cm³
Viscosity (25℃) of 200-700 cps
Non-volatile fraction (60min, 150℃) 50%
Solvent N-methylpyrroliketone
Storage and transportation
Being sensitive to moisture and stored in dry conditions, a slight turbidity during storage does not affect the rheological effect. Storage time is not recommended to exceed 12 months.
application message
Industrial paint
Features and advantages:
When QK4100 is mixed into the coating system, the additives establishes a three-dimensional structure. The formed flexible mobility can prevent settlement and improve flow hang resistance without affecting flow level.
Special attention
Color discoloration may occur if used in conjunction with desiccant. The rheological effectiveness should be evaluated in this case. Pay attention to the yellowing when the addition amount is too high. When used in reaction, catalytic, and nitrofiber systems, we recommend testing storage stability.
PVC resin
Features and advantages:
Can be used in PVC plastic sol, improve touch denaturation. Improve the anti-settlement and antifluid hang performance, and improve the processing efficiency. QK4100 reduces the floating tendency of colored plastic sols. There will be a steady bubble effect.
Recommended dosage
PVC, 0.2% -0.5% of the resin additives dosage (supply form) prevents settlement and floating color.
PVC, 0.5% -1% of resin (supplied form) for fluid protection.
The above data are the empirical amount, and the optimal amount should be determined by a series of tests.
Add method guidance
The additive additives should be added to the coating system under medium shear force to ensure uniform mixing and rapid dispersion, without special temperature control, the additive can be added to the abrasive stage, and is also suitable for later addition to adjust the viscosity. If the additive is suitable for this system, it will significantly increase the rheological effect, depending on the time and polarity, and generally the rheological effect can be evaluated at 2-4 hours after mixing. This aid is recommended for moderate polarity systems.
