What is Acrylic Binder?

Binders, also known as “vehicle” or “medium” is a substance that keeps the pigment of paint in place after the paint dries. It is used to create wet stuff that we call paint. A binder medium can also be defined as an acrylic medium that acts as a sealer which is used to prepare the porous surfaces before applying gesso on it. Gesso is a flexible acrylic ground used to provide a white stable surface on which you paint. Binders provide somewhat “slippery” ground preparation. It can be used as a medium to toughen the paint when needed for conventional acrylic techniques like scratching back or can be used as a glue for collage.

Acrylic Binders Chemical Formula

The binder resin in an acrylic binder or acrylic paint is a man-made product that is mostly made in labs. Generally, it is made from methyl methacrylate monomer and a common real catalyst. The catalyst speeds up the reaction which creates polymethyl methacrylate, known as acrylic plastic polymer .

Acrylic paints are man-made through various chemical reactions. The pigments are mostly made in labs, either they are pure elements like pure cobalt powder and carbon charcoal or basic bounded compounds like cadmium sulfide. Cadmium sulfide is made by reacting cadmium chloride with hydrogen sulfide to make a bright yellow solid. Then, this solid is washed and heated to make the spectrum of different colours.

Acrylic Paint Binder

Chirag Enterprise offers Methyl Methacrylate monomer that is used to make binder and further used to manufacture acrylic paint Acrylic binder is the most amazing medium for fine art painters. The development and research in acrylic, has taken it far beyond than any other medium like oil and water colour. If we compare acrylic to any other medium that is available for the painters then it would be like comparing a Photoshop computer application to an old-fashioned typewriter. What it means is that acrylic binder offers a vast range of painting potential. If we would approach acrylic as if we are using oil or water colour to paint then it would limit its wide range of possibilities.

Acrylic Binder for Textile

Acrylic binder can be optimised easily depending upon the type of textile performance requirement that includes tensile strength, dimensional stability, chemical resistance and water permeability.

Acrylic Binder for Glass Fibers

Acrylic Binders that are designed to meet the requirement of glass fibre applications including roofing membranes, filtration media and mats, building insulation. Self-crosslinking binder that consists of no formaldehyde and maintains the properties can surely help to meet your goal.

Types of Acrylic Binders

There are mainly three types of acrylic binders . As mentioned above, acrylic binders are used to combine the colour pigment of acrylic paints. They are called paint because they have colour in them. And the rest of the substance is called binders that are usually without colour. It can be divided into three main categories – Medium, Pastes and Gels. The difference between these categories is mainly consistency, transparency and drying times. Let’s know more about these differences to understand the three categories –

  • Consistency: Mediums are thin and pourable to make the paint or the surface smooth. On the other hand, gels and paints are thick, that adds texture to the surface or the paint.
  • Transparency: Mediums and Gels are purchased according to the different type of shine you want for the paint or the surface. It comes in three types – gloss, matte and sometimes semi-gloss. When we apply the gloss version, it looks transparent on the surface. Whereas, matte and semi-gloss versions look slightly milky or translucent when applied on the surface. Paste looks opaque on the surface or paint layers. Each type of paint and binder has its own quality of transparency and opacity. We can even customize the transparency and opacity of the paint by mixing it with an acrylic binder.
    Here at Chirag Enterprise, we serve Methyl Methacrylate monomer which makes the binder look glossy, matte and semi-glossy.
  • Drying Times: Another factor by which we consider between medium, gel and paste is the different drying times. Adding gels to the paint slows down the drying time, or in another way, it increases the open time. To allow the paint to dry faster, we can add pastes as it dries down the paint quickly. There are some mediums that are also used to reduce the drying time of the paint or make it extra slow.

Styrene Acrylic Binder

Styrene acrylic is a modified acrylic polymer which increases the weathering resistance of the polymer. It is a copolymerization between styrene and different esters of the acrylic acid. It is a formaldehyde-free, general-purpose binder and is used for the production of indoor/outdoor emulsion paints, natural stone plasters, exterior architectural coatings, textured finishes and ready-made plasters.

The performance advantages of styrene-acrylic binders include water resistance, flexibility, scrub, gloss, durability and abrasion resistance. It has great pigment binding power and is particularly suitable as a binder for emulsion paints and resin-bound plasters with high weathering stability.
