Product Description:

Product introduction

HEMC is made from highly pure cotton - cellulose by reaction of etherification under alkaline conditions without any organs of animals, fat and other bioactive constituents.

HEMC is featured by hygroscopicity and hardly soluble in hot water, acetone, ethanol and toluene. In cold water, HEMC will swell into colloidal solution and its solubility is not influenced by PH value. Similar to methyl cellulose while being added to hydroxyethyl groups, HEMC is more resistant to saline, easily soluble in water and has higher gel temperature.

Q:What is a binder additive for asphalt and how do they apply them in the driveway?
Most asphalt additives are added at the plant where the paving materials are mixed. Otherwise you are dealing with a surface applied sealer. There are numerous additives for asphalt and each has a different issue they are improving. The specific additive they have suggested will have literature available that will cover the dosage, application, condition requirements, issues it proposes to resolve and if it increases the time before it needs to be resealed the literature will provide their claims. The paving contractor should provide the product literature for your review and comments. It is entirely possible an additive is available and probably there are many on the market. Review the product literature and make a decision based on the added cost and the value received. Sometimes surface sealers are applied as much for their appearance as their protection of the asphalt from oils etc. Once you start the sealer applications you will have to continue them periodically due to the surface wearing in the traveled portion of the drive.
