How RDP Enhances Crack Resistance in Thin-Bed Tile Adhesives
Thin-bed adhesives (typically 3–6 mm thick) rely on cementitious binders for strength. While cement provides rigidity, it lacks flexibility, making the adhesive prone to microcracks as substrates shift or environmental conditions fluctuate. These cracks compromise bond integrity, leading to tile ...Read more -

Hydroxyethyl Cellulose (HEC) in Ceramic Glazes
Why Use HEC for Ceramic Glazes? Key Benefits 1. Superior Viscosity Control HEC acts as a non-ionic thickener for ceramics, enabling precise adjustment of glaze viscosity. This ensures even coating on complex shapes and reduces drips or uneven finishes. 2. Enhanced Clay Suspension As a clay suspen...Read more -
RDP’s Role in Improving Mortar Adhesion on Challenging Substrates
What Are Challenging Substrates? Challenging substrates are surfaces where traditional mortars struggle to bond effectively. Common examples include: Non-porous materials (e.g., glass, metal, glazed tiles). Smooth or polished concrete. Aged or contaminated surfaces (e.g., oil-stained floors). Th...Read more -
HEC vs. HPMC: What’s the Difference and Which Should You Use?
In the world of cellulose ethers, Hydroxyethyl Cellulose (HEC) and Hydroxypropyl Methylcellulose (HPMC) are two widely used additives with overlapping yet distinct properties. Both are derived from natural cellulose and serve as thickeners, stabilizers, and water-retention agents, but their chemi...Read more -
Impact of HPMC on Workability and Open Time of Mortars
What Is Workability in Mortars? Workability refers to how easily a mortar mix can be mixed, applied, and smoothed on surfaces. For tile adhesives, skim coats, wall putty, and plaster, optimal workability means: Smooth application Reduced drag on tools Uniform spread without clumping Less physica...Read more -
