Casco RX Original glue

Casco RX Original is a legendary solvent-based adhesive widely recognized across Scandinavia and Europe. Originally developed in 1943 by Martin Bjurvald, known as 'Dr. RX,' the glue was initially designed to prevent window glass from fragmenting during World War II. Its iconic triangular grey bottle has since become a staple in schools, offices, and households for bonding paper, photos, and leather without causing wrinkles.

Today, the Casco brand is part of the global construction and chemical giant Sika AG. While the brand has deep Swedish roots, manufacturing is integrated into Sika's extensive European production network, often centered in Sweden for these specific consumer adhesive lines. The product remains a market leader for archival-safe hobby and office tasks due to its transparent drying and precision applicator.
