SDS; Order CNTs Dispersant
How to disperse CNTs:
Order CNTs Alcohol Dispersant -- US4496
Order CNTs Ester Dispersant -- US4497
Order CNTs Water Dispersant -- US4498
Example - Using US4498 dispersant to disperse CNTs:
1) Single-walled: US4498 should be 3 to 4 times of carbon tubes;
2) Multi-walled: US4498 should be 0.1 to 4 times of carbon tube (corresponding diameter descending)
3) Step 1, add US4498 into water first. Step 2, when US4498 fully dissolved into water, then add CNTs. Step 3, finally subjected to ultrasonic (this requires the customer's own experience). Order CNTs Dispersion Products
