DS-1140 resin is a copolymer synthesized through the graft copolymerization of (meth)acrylate monomers and specialized monomers onto chlorinated polypropylene, utilizing toluene and methyl ethyl ketone (MEK) as solvents. This resin exhibits excellent adhesion to the vast majority of PP substrates (eliminating the need for a PP adhesion promoter) and is suitable for the formulation of solid-color paints.
The Anti-Corrosion Silicon-Modified Acrylic Resin presents itself as a slightly hazy, viscous liquid with a distinct, sharp solvent scent characteristic of its toluene and methyl ethyl ketone (MEK) base. When poured, the fluid exhibits a smooth, syrupy flow, accurately reflecting its precise H-Z viscosity parameters. Upon application and curing, it transforms into an exceptionally uniform and tough film that feels rigid yet remarkably flexible to the touch. This advanced thermoplastic material is synthesized through the sophisticated copolymerization of (meth)acrylates and specialty monomers, which are meticulously grafted onto chlorinated polypropylene. By integrating silicon-modified anti-corrosion properties, the resulting matrix forms a dense, impenetrable barrier against moisture, chemical exposure, and severe environmental degradation.
Formulators and production engineers will appreciate the seamless integration of this resin into existing manufacturing lines. The solution rapidly wets out pigments and fillers, leaving behind a flawless, high-gloss finish that fundamentally upgrades the visual and tactile quality of automotive components. Because it demonstrates exceptional adhesion to the vast majority of polypropylene substrates, it requires no additional adhesion promoters during application. This allows industrial paint formulators to directly create high-quality solid-color paints, streamlining the entire coating process while ensuring long-lasting, premium results on final assembled parts.

While specifically engineered and grafted onto chlorinated polypropylene for maximum adhesion to PP substrates, it also exhibits highly favorable adhesion to certain polyethylene (PE) blends and ABS plastics. However, because surface energies vary, we strongly recommend conducting thorough substrate-specific testing in your laboratory before initiating full-scale production.
Yes. Due to the flammability and volatility of Toluene and Methyl Ethyl Ketone, the resin must be stored and processed using standard explosion-proof equipment. Operators must use appropriate personal protective equipment (PPE), and facilities should be equipped with adequate ventilation and professional VOC management systems.
The silicon modification introduces highly stable siloxane bonds into the acrylic matrix. These bonds are naturally hydrophobic and chemically inert. Once cured, they significantly lower the surface energy of the paint film, causing moisture and corrosive agents to be repelled rather than absorbed, which dramatically extends the lifespan of the protective coating.
No, one of the primary operational advantages of this thermoplastic resin is its excellent air-drying properties. The solvent system evaporates rapidly at room temperature, allowing the film to set and adhere strongly without the absolute necessity of high-temperature baking, thereby saving substantial energy costs in your facility.
It is primarily designed as a high-adhesion basecoat or primer. However, because it can be directly formulated into high-quality solid-color paints, it can easily serve as a single-coat finish for interior or less demanding exterior applications. For premium automotive exteriors facing severe weather, it is typically overcoated with a specialized clearcoat to provide maximum UV and scratch resistance.
