Thickening Clay

Thickening Clay is a good anti settling agent in paint industry.Paint thickening agent also named oil thickening additive. All anti settling agent from Camp Shinning has good thixotropy, thickening, dispersibility and high-temperature stability in paint formulation.

Anti settling agent also named paint thickening agent and thixotropic agent for epoxy (common name Organoclay ). 

In paint industry, organoclay could use for solvent based paint and water based paint. 

Anti Sagging Agent is adapted for aromatic solvent, ester, ketone, alcohol and resins in medium and high polarity such as two-component polyurethane, fluorocarbon coating, epoxy coating, zinc-rich coating etc.

Organoclay bentonite CAS ：68953 – 58 -2

Advantages:

Good suspension

High thixotropy

Little filtrated volume

Excellent capacity of making mud

Easy to adjust the density of the well drilling slurry

Typical properties:

Bentonite application

Types of bentonite clay CP-DRI is suitable for all type of freshwater mud rotary drilling.

CP-DRI can also be used as a seal for earthen structures, slurry trenching, tunnel boring and foundation drill.

Mixing and dosage:

Mixing ratios are based on the use of freshwater; water purity will affect bentonite performance. For best results, acidic and hard make-up water should be pretreated with SODA ASH to a pH of 8.5-9.5. Add PREMIUM GEL slowly through jet/hopper mixer.The quantity of bentonite used is variable depending upon the depth of the hole to be drilled. Generally one tonne of bentonite is used to prepare about 100 barrels of mud.

Packing:

25kg/bag; or 50kg/bag, packed by 800kg or 1000kg super sacks.

How To Use Thixotropic clay

1. Pre-gel method
2. Polar activator is not necessary:
3. Main solvent xylene: 95~92%
4. Thixotropic clay :5~8%
5. Dispersing 5-15min, gel is finished.
6. Polar activator is necessary:
7. In aromatic solvent, the recommend activator is methyl acohol/water (95%/5%)/ acolhol/water (95%/5%), the dosage is 33%-45% based on the weight of CP-720B.
8. In mineral oil (such as 200#), white oil, diesel oil, the recommend activator is methyl acohol/water (95%/5%)/acolhol/water(95%/5%), the dosage is 33%-60% based on the weight of CP-720B.
9. Procedure of adding gel:
10. Charge solvent and resin to mill
11. Slowly add the gel
12. Dispersing 5-10min
13. Wetting agent (if required)
14. Disperse completely to desired fineness
15. Dilute to desired viscosity
16. Add directly with powder
17. Charge solvent and resin
18. Add Thixotropic clay slowly
19. Disperse 10-15min

D .Add polar activator (if necessary)

1. Disperse 10-15min at high speed
2. Add wetting agent and other additive
3. G.Grind and next procedure

It can be added directly in powder under high shear condition. The addition is recommended to be before grinding procedure to get the best effectiveness. Addition level is commonly 0.1%~2.0%. If add polar activator and make pre-gel, better efficiency can be achieved.
