How does MM38 Acrylic Thickener create thick paint?

      MM38 Acrylic Thickener is a premium paint additive specifically formulated to elevate the viscosity of acrylic paints, enabling artists to effortlessly achieve captivating thick paint effects without compromising the vibrancy of colours. As an ideal alternative to traditional gels and impasto mediums, MM38 Acrylic Thickener serves as a rheology modifier, exerting a chemical influence on the flow and viscosity of the paint. This innovative medium ensures a consistent texture and thickness throughout the artwork without losing colour brilliance. It's worth noting that certain colours may exhibit a slightly reduced sheen in the dried film, which can be easily rectified by applying a suitable varnish after the paint has thoroughly dried

      What is the drying time of MM38 Acrylic Thickener?

      The drying time of MM38 Acrylic Thickener depends on the application's thickness. For a thin coat, a standard estimation is around 48 hours. However, it's important to note that prevailing atmospheric conditions during application, such as humidity, heat, and cold, can influence the drying time. Avoiding forced drying or using the product in temperatures exceeding 30℃ is crucial to ensure optimal drying results. Doing so may lead to premature skinning, which can trap water in the coating and produce an opaque or unsatisfactory finish.
