construction hpmc-HPMC plays three roles in putty powder
HPMC plays three roles in putty powder: thickening, water retention and construction.
Thickening: The cellulose thickens the putty powder and helps to suspend it and keep it in a uniform solution.
Water retention: It makes the putty powder dry slower and assists the reaction of calcium ash under the action of water.
Construction: Cellulose has a lubricating effect, which allows the putty powder to have a good construction, while HPMC only retains water and assists calcium ash to react better, it does not participate in any reaction.
