Thermosetting Acrylic Resins
Thermoplastic acrylic resins are the high molecular, physically curing film forming agents. These resins set by giving off solvents, without undergoing a chemical change during film formation. They offered significantly improved color, color stability and exterior durability over other polymers of similar cost. Thermoplastic acrylics are prepared by the polymerization of acrylic monomers and are usually regarded as inert. The major characteristics of thermoplastic acrylics which govern their use in specific applications are:

Cold Plastic Acrylic Resins
These resins are based on methacrylate monomers which are used for cold plastic marking paints. They are hard, durable, weather resistant and also resistant to some chemicals such as road salts and fuels. The binder contains paraffin which tends to float when stored for a long period of time at lower temperatures. Therefore, it must be homogenized before use by stirring. Tacryl RM965 is the main binder and Tacryl AC100 is used as an activator, which should be added to the paint right before application. This system will be hardened by adding dibenzoil peroxide and it is used for marking pedestrian crossings, stop lines, direction arrows and safety markings with increased night visibility. It’s suitable for manual application with smoothing trowels or draw boxes. Cold plastic materials are usually applied to asphalt and concrete surfaces in layer thickness of 1.5-2.5 mm. The system is totally solvent free so the thickness of wet and dried film is nearly the same. The reaction will be ended after 30 minutes and the coating will be ready to use.
Reactive Acrylic Resins
These resins are based on methacrylate monomers which are used for cold plastic marking paints
Two Component Hydroxy Acrylic Resins
Two component isocyanate cure acrylics can be attributed to two main factors. The first is the urethane linkage which is formed at ambient temperature by the reaction between the acrylic polyol and the isocyanate pre polymers
Prosthesis Acrylic Resins
Tacryl PRO is a two component resin based on methyl methacrylate for manufacturing orthotic and prosthetic sockets. This system will be hardened by adding dibenzoil peroxide. The prosthesis which have been manufacturued by PRO own higher strength and lighter weight even in thinner thicknesses
Low Profile Low Shrinkage Additive
This product is solution of poly methyl methacrylate (PMMA) in Styrene which is recommended as low profile and low shirinkage (LP/LS) additive for SMC/BMC parts in automotive and other industries. Unsaturated polyester resins give rise to volume shirinkage of 7 to 9% during curing, therfor, leading to SMC/BMC molding have marked rough surface warpage, cracks marks. These problem have successfully solved by adding BM852.
Plastic Coatings Plastic substrates require special consideration because of four major concerns: Heat sensitivity Low energy Surface solvent sensitivity Flexibility The low energy surface of some polymers can created problems with adhesion. Substrates such as poly olefins, poly propylene and poly ethylene are extremely difficult surfaces on which to achieve proper and sufficient adhesion. Acrylic […]
The coating system on wooden surfaces is expected to cope with many different requirements depending on the particular application. What all coating systems have in common is that they must have an attractive appearance and good adhesion between the individual layers of the coating. In the case of interior applications such as furniture and doors, […]
Thermoplastic acrylic polymers are used in the decoration and protection of masonry and concrete, for both interior and exterior applications. Due to the highly alkaline nature of most masonry materials, one of the fundamental properties required for high performance long-life coatings on such a substrate is resistance to saponification.
Marine coatings are special- purpose coatings that are supplied to the shipbuilding and repair offshore and pleasure craft markets. The used products are diverse and unique and are formulated for severe climate and immersion conditions. As a result of these conditions, the coatings used must have maximum resistance properties to salt spray and constant sea contact and a broad range of chemicals. Two component iso ciyanate cured acrylic paints are used as finishes on epoxy systems. Due to urethane bonds, they have high environmental resistance especially excellent radiation resistance, which protect epoxy systems from chalking.
Nearly all the industrial installations, machines and industrial spare parts have to be coated in a protective way. High chemical and physical resistance in severe conditions can be achieved by means of these coatings.
House Hold Appliances Paints
A major substrate encountered in buildings is metal, with ferrous metal being of greatest significance. Whereas wood and masonry are most conventionally grouped under the general heading of building paints, ferrous substrates encountered in virtually all market sectors. Thermoplastic acrylic paints can be used with high gloss retentions and they are easy to use. On the other hand thermosetting acrylic paints with excellent mechanical and physical properties such as high scratch resistance and gloss retention are accessible.
Automotive Lacquers and Paints
The severe demands and accurate performances required for automotive coating are considerable. There is a need for body protection, such as anti- corrosion and stone chip resistance for a durable and appealing finish. Products also have to be appropriate to mass-production conditions and in this respect, must be robust, flexible and economic to use. Thermosetting acrylic-amino resins are used in OEM section of automotive paints and two component isocyanate curable acrylic resins are used in automotive refinishes.
