Construction Additives

Additives for the construction industry

For the construction industry, LEVACO provides different performance additives which enable the end-users to achieve the best quality and usability of the construction materials.

LEVACO offers a series of specialized additives targeting the producers of dry-mortar for rendering, gypsum and cement-based tile adhesive.
The portfolio comprises the key elements in such formulations: the control of air-pores after mixing with water and the control of the desired rheology of the finished product. LEVACO products can define sag-resistance of cement-based tile adhesive, set the desired water factor in rendering mortar or minimize the emerge of pinholes in self-leveling formulations.

LEVACO provides a selection of key performance additives for the dry mortar and cement board industry.

DEFOSPUM^® Powder defoaming agents as an additive for dry mortar and construction materials.
LUCRAMUL^® Wetting agents for dry powder applications.
LUCRAMUL^® Wetting agents for waterborne formulations.
LUCRAMUL^® Dispersants for waterborne and dry powder building materials.
Highly efficient DEFOPOL powder form thickeners for the production of dry powder-based tile adhesives, renders, plasters and grouts.

Additives for construction materials

DEFOPOL series - the key to rheology control in dry-mortar technology

Fundamentally improved sag resistance, pumpability, waterloss prevention, wall-adhesion and improved leveling properties with our DEFOPOL product series.

DEFOPOL SW grades - a powdered anionic polyacrylamide copolymer building material thickener for various applications in plaster and cement mortars, fillers, building adhesives, floor and joint systems.

DEFOPOL C1005F is a non-ionic powdered polyacrylamide building material thickener, that fixes the water demand and workability parameters in machine-applied gypsum mortars and cement-lime plasters

DEFOPOL products can be used for compounds comprising other additives like plain methylcellulose derivatives, plasticizers, defoamers, and starch ethers.

DEFOSPUM^® PE 11 – antifoaming agent

During mixing and manufacturing of construction materials (self-leveling mortar, float finish, injection mortar, gypsum putty, fibre cement panels, etc.) an efficient deaeration of the mixed material is needed for a flawless appearance.

With our DEFOSPUM^® PE 11, LEVACO offers a state-of-the-art powder defoaming agent for foam-sensitive formulations.

LUCRAMUL^® & LUCRACHEM^® series – special construction additives

LEVACO offers a series of specialized additives targeting the producers of building materials.

LUCRAMUL^® products provide fast wetting in self-leveling grouts, ease of leveling in gypsum plaster or durable air-pores in batch mixed wet mortars.

LUCRACHEM^® AD MO is added to powdery mixes to eliminate dust in handling. Especially bagged cement-based mixes can gain from this application feature.

On the organic chemical side of construction materials, LUCRACHEM^® EPC products are constituents of high-performance thermal insulation foams for construction application.

Further LEVACO manufactures specialized emulsifiers for bitumen emulsion and concrete release agents.

Product overview LUCRAMUL^® & LUCRACHEM^®

LUCRAMUL® AEA	Non-ionic Air-Entraining Agent in powder form with medium air-entrainment effect and high pore stability. Also employed as fast wetting- and plasticizing agent for flowable mortars and grouts.
LUCRAMUL® U-Flakes	Non-ionic AEA in flaked form for the preparation of wet mortar and ready-mixed mortars. Medium air-volume entrainment paired with extreme pore stability.
LUCRAMUL® DAC 220	Dispersant and plasticizer for the rheological modification of gypsum and cement-based building material compositions.
LUCRACHEM® AD MO	Liquid, dust-reducing additive with self-emulsifying properties for dry powdery mixes, especially tile adhesive.
LUCRACHEM® EPC grades	Bifunctional polyether polyols for the manufacturing of foams with low thermal conductivity. The material is used in the manufacturing of high-performance thermal insulation boards and foams.
