GOLDEN SoFlat Matte Acrylic Paint Permanent Yellow Deep 473 ml — Ultra-Matte, High-Coverage

This 16 fl. oz. jar of Permanent Yellow Deep (PY83/HR70) from GOLDEN is formulated to help artists create broad, uniform fields of deep yellow-orange colour with fewer layers than traditional acrylics. SoFlat sits in a niche between conventional acrylics and gouache: it dries to a velvety, water-resistant surface with very low sheen while maintaining the adhesive strength and durability of acrylic polymer. The paint’s single-pigment diarylide yellow offers strong tinting power, ASTM I lightfastness, and vegan-friendly formulation—attributes professional painters rely on.

How does SoFlat achieve a true matte finish without sacrificing coverage?

SoFlat’s formulation balances matting additives with high-opacity pigments and flow improvers so pigments level evenly and hide the substrate. The result is a flat finish that still reads saturated rather than dull or chalky. Its semi-opaque nature helps preserve vibrancy while allowing for predictable mixing.

• Unique binder and matting blend for low-gloss finish
• High-pigment load for better hide with fewer coats
• Flow and leveling agents reduce brush marks and texture

What makes Permanent Yellow Deep (PY83) suited to professional work?

Permanent Yellow Deep is a single pigment diarylide yellow noted for consistent colour strength and excellent lightfastness (ASTM I), which means finished pieces resist fading under normal display conditions. The semi-opaque coverage provides dependable layering, glazing, and mixing behavior for studio applications where colour stability matters.

• Pigment: PY83 (Diarylide Yellow HR70) for predictable tinting
• ASTM Lightfastness I (Excellent) for archival performance
• Vegan formulation made in the USA by an experienced, employee-owned company

How does SoFlat handle in practical use—brushwork, drying, and durability?

Brush application yields smooth, even passes with minimal drag; the paint levels to a consistent matte film that hides brushstrokes better than many acrylics. Drying time is typical for acrylics, but the film cures to a durable, water-resistant surface that accepts additional layers and varnishes if desired. It’s also easier to cover large areas cleanly, cutting down on glazing and scumbling steps.

• Brushes glide with improved leveling and reduced brush texture
• Dries to a velvety, water-resistant surface ideal for varnish or further work
• Good adhesion to standard primed surfaces; suitable for canvas, panel, and primed paper

How does this paint fit into a studio workflow compared to other GOLDEN lines?

SoFlat is intended where a consistent, glare-free field of colour is paramount—mural underlayers, matte backgrounds, colour blocks, and contemporary minimal surfaces. It requires fewer coats to reach opacity than some other acrylic ranges, letting artists work faster while achieving the flat aesthetic of gouache with acrylic permanence and water resistance.

• Use for large uniform areas, colour-field painting, and matte finishes
• Mixes predictably with other GOLDEN acrylics for extended palette options
• Reduces layering time when a low-sheen result is required

Who is this for: Artists and studios seeking a professional, deep diarylide yellow that lays down even, low-gloss colour—especially painters working in colour field, illustration, set design, or any application where glare-free surfaces and reliable coverage are essential. SoFlat is a good choice for professionals who want archival pigments, smooth leveling, and the tactile matte quality of gouache with the durability of acrylic.
