New non-combustible materials certified by the Minister of Land, Infrastructure, Transport and Tourism.
BRG stands for "Basalt Fiber Reinforced Acrylic Resin Gypsum," which is a completely water-based molding material made from basalt, acrylic resin, and gypsum. By adding acrylic resin to gypsum, the strength of the gypsum itself is improved, addressing its brittleness, and overcoming the poor secondary adhesion that was a drawback of gypsum after curing. Additionally, by introducing basalt fibers as reinforcing fibers, it enables the formation of thin films, allowing for lightweight molded products. Since the base material is gypsum, it is similar to GRG (Glass Fiber Reinforced Gypsum), but it can be molded using hand lay-up techniques like FRP, allowing for bag-shaped three-dimensional molding as well. Using a non-combustible certified grade, molded products made according to our specified non-combustible standards have passed the performance evaluation tests stipulated by the Building Standards Act and are recognized as non-combustible materials certified by the Minister of Land, Infrastructure, Transport and Tourism. With the acquisition of the certification number, it is currently gaining attention as an alternative to interior materials produced with GRG. Additionally, from the perspective of reducing plastic use and environmental considerations, it is also being highlighted as an alternative to FRP.

basic information
【Molding Process】 ■Surface Layer (Usable Time 15min) - Apply a coating mixture of acrylic resin and gypsum for the surface onto the female mold. - Increases scratch resistance and water resistance of the product surface. ■1 Layer, 2 Layer (Usable Time 25min) - Use a coating mixture of acrylic resin and gypsum for bonding to apply basalt cloth on the inside of the surface layer. ■Curing (Demolding Time Approx. 16h) - Completion of a non-combustible molded product that is smooth in surface finish, strong, and has moderate flexibility. ■Painting - By using water-based putty and water-based paint for finishing, production can be entirely water-based. - Being entirely water-based significantly improves the working environment. *For more details, please refer to the PDF document or feel free to contact us.
