About SRL Materials
SRL Materials (SRL Dental GmbH, Ludwigshafen) is a specialist in gypsum and powder solutions and the successor to the former Dental business unit of BK Giulini GmbH. The company produces dental gypsums of types 2–4 according to EN ISO 6873, gypsum- and phosphate-bonded investment materials, industrial gypsums, pharmaceutical calcium sulfate, food-grade calcium sulfate E516, creative gypsums, and the multi-component casting resin system Gil-Resin® for porous press molds in the ceramics industry. Based on a patented process, synthetic calcium sulfate alpha-hemihydrate is produced in high purity. In addition, SRL GIALLOY dental alloys are offered. In the white label/OEM area, the company develops and fills customer-specific powder formulations in packaging sizes from 1 kg paper bags to 1000 kg big bags, including individual colors and properties such as hardness, drying time, or flowability. The products are distributed worldwide and used in industries such as dental, casting technology, ceramics, pharmaceuticals, food, paper, and construction.

Materials and Processes
Calcium sulfate alpha-hemihydrate (synthetic)
Produced according to the company's own patented process for dental gypsums and hard-casting gypsums in high purity.
Calcium sulfate beta-hemihydrate
Base for industrial gypsums and for quality improvement in technical applications.
Calcium sulfate anhydrite
For industrial applications in casting technology and engineering.
Calcium sulfate dihydrate (E516, food/pharmaceutical grade)
Used as a tabletting filler, for texture improvement in foods, and as a filtration agent.
Gypsum-bonded investment materials
For precision casting using the lost-wax process in jewelry and art casting.
Phosphate-bonded investment materials (Gilvest)
For dental model casting technology with smooth surfaces and precise detail reproduction.
Gil-Resin® casting resin system
Multi-component casting resin for porous press molds in the ceramics industry.
SRL GIALLOY alloys
Dental alloys with unique casting and milling properties as a complement to gypsums and investment materials.
Additives (quartz, calcium carbonate, cement, glass fibers)
For targeted modification of properties such as strength, expansion, and hardness.
