Rise of Counterfeit Acrylic Mounting Techniques Threatens Brazilian Art Market

The Brazilian art and decoration market has experienced a significant surge in demand for acrylic-mounted artworks over the past two years, moving from exclusive galleries and international museums to mainstream popularity among architects and collectors. This increased demand has led to market challenges including the proliferation of inferior imitation techniques that compromise artwork durability. The authentic process, known as Diasec, was patented in 1969 by Swiss chemist Heinz Sourek and involves chemically polymerizing photographs between acrylic sheets using liquid silicone gel, creating a permanent seal that protects against air and UV radiation without traditional glass and frames. The genuine technique offers superior optical properties including enhanced color saturation, three-dimensional depth perception, and a distinctive 'wet look' appearance where images appear immersed within the acrylic. However, cheaper alternatives have emerged including direct UV printing onto acrylic sheets and adhesive mounting methods, both of which lack the durability and visual quality of authentic acrylic mounting. These imitation techniques often show degradation within 12 months through issues like peeling, scratching, silvering effects, and air bubbles. Authentic acrylic mounting provides museum-grade conservation benefits including UV protection and hermetic sealing against environmental factors. Experts advise consumers to verify whether fine art paper is used, confirm chemical polymerization sealing methods rather than direct printing or adhesives, and seek long-term guarantees against delamination when purchasing acrylic-mounted works.
