Audited Supplier CLAYMINTON® 72
Super Dispersible Organoclay for intermediate to high polarity solvent and liquid system
Inorganic Rheological Additive
The super dispersibility of CLAYMINTON 72 rheological additive greatly simplifies the formulation and manufacture of paints, adhesives and sealants containing moderate to high polarity solvents, such as ketones, esters, glycol ethers and ether esters and alcohols. The use of CLAYMINTON 72 offers the manufacturer an opportunity to increase productivity, cut energy and material costs, as well as simplifying the manufacture and post correction processes - all while maintaining the high products quality obtained with conventional organoclay rheological additives.
CLAYMINTON 72 additive is an effective replacement of fumed silica and polyamide wax for desirable thixotropy with lower viscosity but better anti-settling and anti-sagging performance especially in high solid system.
• Easy to use
• No need to pre-gel
• No need for polar activator
• Lower package viscosity while maintaining anti-sagging and anti-settling than polyamide wax
• Consistent development of rheology, improving batch to batch production consistency
• Can be used to post correct
• Improves manufacturing efficiency
• High efficiency
• Cost effective

CLAYMINTON 72 additive is an efficient replacement for polyamide wax and fumed silica in lower package viscosity but requiring better sagging resistance for coating containing moderate to highly polar solvents (Ketones, esters, ether esters and alcohols). This includes polar systems containing some aromatic solvents.
CLAYMINTON 72 may be used in:
• industrial finishes
• automotive finishes
• core washes/foundry paints
• marine paints
• adhesives and sealants
• autobody space fillers
• maintenance coatings
When replacing fumed silica in high or 100% solids systems, evaluate CLAYMINTON 72 both with and without a polar activator.
The level of CLAYMINTON 72 additive to be used in a specific system depends on the degree of thickening.sag control and pigment setting desired. Use levels are typically 0.2-2.0% by weight of the entire formula.When formulating with CLAYMINTON 72, a good starting point is a replacement of the currently usedorganoclay or fumed silica at an equal weight, then optimizing. Less CLAYMINTON 72 additive may berequired because the full inherent efficiency can be obtained, even under ower shear, plant conditions
In many systems, at higher thickener concentration levels, Super-dispersible CLAYMINTON 72 additive ismore efficient than traditional organoclay or fumed silica due to its easy to use
The easy and dependable dispersibility of CLAYMINTON 72 additive permits its additive at any point in the manufacturing process. This rheological additive can be incorporated in the dispersion phase under high shear and in the letdown tank under lower shear. Neither a polar activator or a pregel is required.
Using the Grind
CLAYMINTON 72 may be incorporated anywhere during or after the pigment grind. Prewetting or predispersion is not necessary. Minimum activation temperature is not required.
Use in the Letdown
When CLAYMINTON 72 is used in the letdown, it should be sifted in and good turbulent mixing conditions provided. For best performance in the letdown, the system should be between 24°C-32°C (75°F-90°F). If letdown temperatures are too high, CLAYMINTON 72additive may still be used either, a) by pulling out part of the batch and adding the CLAYMINTON 72 on a high-speed disperser or b) prewetting the CLAYMINTON 72 powder with solvent. The prewet powder may then be added to the hot letdown and mixed in.
Do not post add CLAYMINTON 72 to systems containing primarily aromatic solvents.
