SolutionConstruction & Dry-Mix Mortar Solutions

Mineral solutions for skim coat, dry-mix mortar, tile adhesive, lightweight insulation mortar, fire-resistant boards and decorative construction materials.

Construction & Dry-Mix Mortar Solutions
Improved workability

Bentonite and lamellar minerals support water retention, body, sag resistance and easier application.

Crack-control support

Mica and talc help build a stable mineral skeleton in putty, mortar and decorative systems.

Lightweight insulation options

Expanded vermiculite supports lightweight, thermal insulation and fire-resistant construction products.

Application Areas 

Wall putty and skim coat

Mineral fillers influence spreadability, sanding behavior, surface smoothness and crack-control performance.

• Mica for lamellar reinforcement

• Talc for smooth filling and surface feel

• Bentonite for rheology and water retention

Dry-mix mortar and tile adhesive

Mineral additives support body, stability and workability in cement-based or gypsum-based powder systems.

• Powder flow and storage stability

• Consistency in batch production

• Suitable for common construction packaging

Lightweight insulation mortar

Expanded vermiculite can reduce density while contributing thermal insulation properties.

• Low bulk density option

• Thermal insulation structure

• Used in fire-resistant and lightweight systems

Fire-resistant boards and panels

Vermiculite and mica-based mineral systems can be used where heat resistance and board structure are required.

• Board and panel formulations

• Mineral skeleton support

• Suitable for pilot formulation trials
