Laroflex MP resin, with its full name as copolymer of vinyl chloride and vinyl isobutyl ether, its other name is VC Copolymer MP resin, Vinyl Chloride Copolymer Resin. it is produced by polymerization of vinyl chloride monomer, vinyl isobutyl ether monomer and other raw and auxiliary materials, and mainly used in the anti-corrosive coatings and composite printing inks. It is non-toxic, environmentally friendly, superior in the aspects of flexibility, heat resistance, UV stability, alkali and chalking resistance. Application: MP resin for coatings The Anti-corrosion performance index of MP resin is higher than that of Chlorosulfonated Polyethylene and Chlorinated Rubber coatings, therefore it is widely used in the fields of anti-corrosion coatings: Ø  Industrial anti-corrosion coatings, such as factory buildings, equipment, pipeline, tanks, municipal engineering, piers and harbors, etc. Ø  Marine coatings, applicable to the various parts of the hull, resisting sun exposure and seawater erosion. Ø  Transport paints, such as containers, transport machinery, dangerous chemicals tankers. Ø  Light metals primer, top paint, such as garage doors and windows, roof rain sinks, balcony, lampposts and road crash barriers. Ø  Large-scale key projects, such as bridge, ocean and energy engineering. MP resin for inks As an excellent binding vehicle for composite printing inks, it is used in wide range of fields. MP resin has the following advantages: Ø  Good solubility: Soluble in most of solvents, such as benzenes, acetones and esters commonly used in inks production, in addition, the dissolved solution has a higher degree of transparency. Ø  Excellent blending property: Easily blended with other ink binding vehicles to enhance its working performance, such as CPP, EVA and CEVA resins. Ø  High dispersivity: It has good dispersing and wetting properties to inks and dyes, ensuring the pigments fully display the primary color and transferability. Ø  Superior adhesion: The polymer chains contain a large quantity of ether bonds, which have strong adhesive strength to BOPP, OPP, PET and other plastic film. Ø  Good stability: There is no reactive double bonds, no saponifiable ester bonds in the resin, and the chlorine atoms in the molecular link are very stable. These offer ink layers strong resistance to heat, light, weathering, yellowing and chalking. We are proud to share that Sunman's MP resins have achieved industry-leading standards in both product performance and cost-effectiveness. This product series has successfully replaced the Laroflex MP series from over a decade ago, while obtaining European REACH certification. It has gradually become the product of choice for clientele across Europe, Asia, the Americas, and other continents.

Chlorinated polypropylene(CPP) is a versatile material with a range of applications, particularly in industries that require strong adhesion, durability, and resistance to various environmental factors. Below is a detailed overview of the types of chlorinated polypropylene and their applications: Types of Chlorinated Polypropylene (CPP): Low Chlorine Chlorinated Polypropylene (Chlorine Content Below 26%) Applications: Primarily used in the ink and coating industries. Characteristics: Offers good adhesion and compatibility with various substrates, making it suitable for formulations where lower chlorine content is preferred. Benzene-Soluble Chlorinated Polypropylene (Chlorine Content 28%-35%) Applications: Widely used in the ink industry, especially for BOPP (Biaxially Oriented Polypropylene) composite inks. Characteristics: Provides excellent adhesion to polypropylene surfaces and other materials like polyethylene, paper, and foil. Ester-Soluble Chlorinated Polypropylene (Chlorine Content 36%-40%) Applications: Also predominantly used in the ink industry, particularly for applications requiring high chlorine content for better solubility and performance in specific formulations. Characteristics: Similar to benzene-soluble CPP but with higher chlorine content, which can enhance certain properties like flame retardancy and solubility in ester-based solvents. Applications of Chlorinated Polypropylene: Printing Inks: BOPP Composite Inks: CPP is extensively used in the production of inks for BOPP films due to its excellent adhesion properties.It is particularly suitable for packaging materials where strong bonding is required. Formulation Adjustments: Since inks are complex chemical mixtures, the specific type of CPP used may require adjustments in the ink formulation to achieve the desired properties. Plastic and Metal Bonding: Adhesion: CPP's ability to adhere to various materials, including polyethylene, paper, and foil, makes it valuable in industries that require strong bonding between different substrates. Composite Materials: Used in the production of composite materials like PP film-paper and PP film-aluminum, which are commonly used in packaging. Summary Chlorinated polypropylene is a highly adaptable material with significant applications in the printing ink, plastic, and metal bonding industries.Its excellent adhesion properties, combined with resistance to abrasion, saltwater, and aging, make it particularly valuable in the production of packaging materials and composite films.The different types of CPP, categorized by their chlorine content and solubility, allow for tailored use in various industrial applications, ensuring optimal performance in each specific context.

Water-based inks are a type of printing ink that uses water as the primary solvent instead of volatile organic compounds (VOCs). They are widely used in various printing applications, such as packaging, textiles, and paper products, due to their environmental friendliness, low toxicity, and ease of use. Water-based inks are particularly popular in industries where sustainability and safety are priorities. Key Features of Water-Based Inks: 1.  Eco-Friendly: Water-based inks contain fewer harmful chemicals and emit minimal VOCs, making them safer for the environment and human health. 2. Versatility: They can be used on a variety of substrates, including paper, cardboard, textiles, and some plastics. 3. Odorless: Unlike solvent-based inks, water-based inks have little to no odor, making them suitable for food packaging and indoor applications. 4. Easy Cleanup: Water-based inks can be cleaned up with water, reducing the need for harsh chemicals. 5. Durability: When properly cured, water-based inks offer good resistance to abrasion, water, and fading. The formulation of water-based inks typically includes the following components: 1. Pigments (10-30%) · Provide color and opacity. · Common pigments include organic and inorganic compounds (e.g., titanium dioxide for white, carbon black for black). 2. Resins/Binders (20-40%) ·Act as the adhesive that binds the pigment to the substrate. ·Common resins include acrylics, polyurethanes, and styrene-acrylic copolymers. 3. Water (30-50%) ·Serves as the primary solvent to dissolve or disperse the other components. ·Evaporates during the drying process. 4. Additives (5-10%) ·Surfactants: Improve wetting and dispersion of pigments. ·Defoamers: Prevent foam formation during mixing and application. ·Thickeners: Adjust viscosity for better printability. ·Plasticizers: Enhance flexibility and adhesion. ·Biocides: Prevent microbial growth in the ink. 5. Co-Solvents (5-15%) ·Improve drying time and film formation. ·Common co-solvents include ethanol, isopropanol, and glycol ethers. Applications of Water-Based Inks: ·Flexographic Printing: Used for packaging materials like corrugated boxes, labels, and bags. ·Gravure Printing: Common in high-quality publications and decorative papers. ·Screen Printing: Popular for textiles, posters, and signage. ·Digital Printing: Used in inkjet printers for commercial and industrial applications. Water-based inks are a sustainable and versatile choice for modern printing needs. Their formulation can be customized to meet specific performance requirements, making them suitable for a wide range of applications.
