Enhanced Adhesion and Bonding Strength Redispersible Polymer Powder significantly improves the bond between cement-based materials and various substrates like concrete, plaster, or tiles, ensuring a more durable and stable construction. Increased Flexibility and Crack Resistance The polymer enhances the flexibility of mortars, reducing the risk of cracks and fractures due to structural movement or environmental […]

Reason: The water temperature fluctuated greatly during dissolution, resulting in uneven dissolution of HPMC. Insufficient stirring time or too short resting time, HPMC is not completely dissolved. HPMC batch differences or improper storage conditions affect viscosity stability. Solution: Maintain a constant water temperature during the dissolution process, stir and leave it for enough time (usually […]

HPMC is very sensitive to temperature and exhibits significant differences in dissolution characteristics at different temperatures. Therefore, it is necessary to control the water temperature to prevent sudden changes in viscosity or incomplete dissolution.HPMC usually disperses better in cold water, while it tends to swell or agglomerate in hot water. Solution: Avoid using high temperature […]

Water Retention: HPMC is highly effective in retaining water in construction materials, preventing the premature drying of mortars and improving their workability. This ensures that the materials remain workable for longer periods, allowing for better application. Improved Adhesion: HPMC improves the bonding strength of building materials such as tile adhesives, gypsum-based products and cement-based plasters. […]

HPMC is a cellulose derivative. It is widely used in the construction, daily chemical and pharmaceutical industries, which is generally safe for human use. Construction In construction, HPMC is used in products such as tile adhesives, wall putty and other mortars. In this context, the main exposure route for humans is through skin contact during handling or inhalation […]

Applications for VAE-RDP include the formulation of building materials such as tile adhesives, grouting, finishing plasters, smoothing compounds, thin mortars and sealing pastes. The amount of VAE-RDP added to cement and mortar is approximately 2-10%, depending on the desired increase in strength, impact resistance, adhesion and water resistance of the compound. For wall tile adhesive […]

Vinyl acetate and ethylene are copolymerised in an emulsion process to produce a VAE composition with an ethylene content of 10% to 40% in the copolymer in the first instance. Ethylene is a soft, hydrophobic monomeric unit in the copolymer that acts as the internal “plasticising” part. In the copolymer, ethylene effectively lowers the glass […]

In dry mix mortar, adding a little HPMC can significantly improve the performance of wet mortar. It can be seen that HPMC is a major additive that affects the construction performance of mortar. ● Water Retention Water retention is an important property of HPMC. The viscosity, dosage, environmental temperature and molecular structure of HPMC have […]

1.HPMC can improve the cohesion and water retention of the wet mortar mixture, but excessive mixing will reduce the consistency of the wet mortar mixture. Water retention rate is an important performance index of wet-mixed mortar. While some components of mortar and concrete are the same, they function differently. Typically, concrete is poured into concrete and […]
