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 […]

Cellulose ethers (CEs) are used to improve the workability of cement mortars while maintaining the water holding capacity and fluidity . HPMC is the most widely-used CE. High water retention improves the cement hydration and limits the absorption of the mixing water by a substrate and thus provides good mechanical and adhesive properties to the […]

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. Generally, a small amount of HPMC can greatly increase the water retention rate of the mortar. When the content reaches a certain […]

1. Supplier Verification: The first step in ensuring RDP quality and authenticity is to establish trust in your supplier. Research and choose reputable manufacturers or distributors known for producing high-quality RDP. Look for certifications and industry affiliations, which can be indicative of a commitment to quality. 2. Material Data Sheets (MDS): Request Material Data Sheets […]
