Plasterboard additives

Lignosulfonates

The main role of lignin in concrete is to reduce the amount of water. When formulated in the finished admixture, it can be used either to improve the workability of the mixture and simplify the placement of concrete, or simply reduce the water ratio by increasing strength and reducing permeability.

Boric Acid

Acid that is actively used in the production of drywall and gypsum plasters for the last 60 years. Boric acid has been also applied in plasters to increase hardness. The two components that are used for boric acid were designed to resist sagging, particularly for ceiling tiles, and to prevent the core calcination in the gypsum board dryer, leading to a paper bond failure.

Retarder Agent

Retardants are the necessary additives in the gypsum industry that can delay hardening, allowing it to be processed. It is actively used in plasterboard production and construction. Plaster industry itself is growing rapidly all over the world and is moving towards light, flexible and eco-sustainable constructions, especially regarding the internal building structures.

Vermiculite

Increases fire resistance of the material along with the fiberglass.

Silicon

Great and simple water-repellent treatment of plaster elements, plasterboard or wallboard.

Air Entrainers, Defoaming and Foaming Agents

With any kind of mortar and plaster, controlled formation of the perfect size air bubbles will significantly improve the product. Not only air entrainment surfactants can reduce weight and costs, but also increase the workability, affinity and durability of your end product. Depending on local conditions and mortar or plaster type, we can easily recommend highly functional air bubble products.

Starch

During the drying stage, the solublised starch migrates to the interface with the water, coating the crystals and preventing them from drying out.

Accelerators

Potassium Sulphate helps with a faster setting time of the gypsum board when the speed line increases.

Fiberglass

A textile fiber that stabilises gypsum matrix under the fire load and helps you to preserve the integrity of the wall system. Additionally, both reinforcement types significantly improve board stiffness, allowing to reduce its weight and increase length.
