Product Q&A

Q:What is the main difference between HEMC and HPMC?

HEMC contains hydroxyethyl and methoxy substitute groups, whereas HPMC contains hydroxypropyl and methoxy groups. This makes HEMC more hydrophilic with a higher gel temperature.

Q:Why is HEMC recommended for high-temperature applications?

HEMC has a higher gel temperature than HPMC, allowing it to maintain water retention and thickening effects in hot environments where HPMC might lose viscosity and operability.

Q:What are the primary applications of this HEMC product?

It is primarily used in tile adhesives, thick plastering mortars, and light render plasters, especially where anti-sagging and anti-sliding properties are required.

Q:What is the minimum order quantity (MOQ)?

The minimum order quantity is 500 Kgs.

Q:Does the supplier offer OEM or ODM services?

Yes, both OEM and ODM services are available, along with full customization, minor customization, and customization from samples or designs.
