M513RA is an orthophthalic based, medium reactivity, low viscosity, thixotropic, pre-accelerated Unsaturated Polyester Resin. The resin provides excellent adhesion on acrylic sheets. It is suitable for hand lay-up and spray-up applications. It’s applied on the back of acrylic products with glass roving to give extra strength. M513RA is white pigmented and due to its thixotropic nature, it is easily applied on vertical surface. Slightly blue colored version is available with MEK peroxide in the mixture. The blue color disappears when hardener is added.
