Chlorinated Polypropylene (CPP) is a versatile functional polymer that has gained widespread use across multiple industrial sectors due to its exceptional adhesion properties, compatibility with various resins, and ability to modify surface characteristics of low-energy materials. Below are the three primary application fields of CPP, each playing a critical role in modern manufacturing and coating technologies. 1.CPP for Inks (Chlorinated Ink Resin) High-molecular-weight CPP is specifically designed for printing inks on PP substrates, available in both toluene-soluble and ester-soluble systems. It is mainly used in packaging printing to effectively enhance ink adhesion on PP film surfaces, preventing the printed layer from detaching during processing or end-use. The most common end-use is in rotogravure and flexographic printing of PP films, which are extensively used for snack food packaging, confectionery wraps, shrink sleeves, and laminated stand-up pouches. The inherent non-polar nature of PP films causes conventional inks to exhibit poor wetting and weak anchorage, leading to smudging, rubbing, or complete detachment during handling or transportation. By utilizing high-molecular-weight CPP as the ink vehicle or as a co-binder, the ink layer forms a strong physical and chemical bond with the PP surface, ensuring excellent rub resistance, block resistance, and adhesion even under high-speed printing and subsequent converting operations. Additionally, the high molecular weight imparts improved pigment wetting and dispersion stability, resulting in vibrant colors and consistent print density across long production runs. 2. Adhesion Promoter for PU Inks Low-molecular-weight CPP is used as an adhesion promoter for PU inks, primarily to solve adhesion problems on PP and PE films. This application is common in packaging printing, where it strengthens the bond between the ink layer and low-surface-energy substrates, effectively preventing ink peeling, smudging, and other defects, thereby ensuring print quality. 3.Automotive Coatings and Adhesives CPP exhibits strong affinity for polyolefin substrates such as PP and TPO, and shows good compatibility with resins like acrylics and polyurethanes, significantly improving coating adhesion. Specific applications include: •Automotive bumper coatings (high-flexibility grades); •Interior trim coatings (low-VOC, environmentally friendly formulations); •Adhesion-promoting primer layers for polymer substrates; •Adhesives for structural bonding of PP to metals and PP to rubber. We can supply many different types of CPP resin. So any more informations, pls let us know.

What is reflective paint? Reflective paint is made by mixing directional reflective materials in a solvent. Acrylic resin is the base material. Reflective paint is a new type of reflective paint. It reflects light through reflective beads. It has better reflective effects at night. Due to high reflectance, it can prevent ultraviolet light irradiation and color fading. It is also highly resistant to salt spray, acid and alkali. How to use reflective powder for paint? Method 1: Reflective paint is made by directly mixing reflective powder with paint. It is easy to use and control. Reflective powder is used according to the reflectance. Method 2: Preparation of reflective paste: Weigh an appropriate amount of reflective powder, and mix it with the solvent (cyclohexanone) into paste. Then, mix it with transparent printing paste by stirring. Reflective powder will be half exposed on the surface, to achieve the reflective effect. Reflective powders of different particle sizes have different reflective effects. (Different particle sizes will lead to better reflective effects.) What is reflective paint used for? Applications of reflective powder in paint 1. Traffic signs Reflective powder is an important material of traffic signs. If reflective powder is used in paint of traffic signs, traffic signs will be clearly visible at night. This can improve the road safety. 2. Architectural decoration Reflective paint is also widely used in architectural decoration. When reflective paint is applied on the surfaces of buildings, the visual effect of buildings at night will be enhanced. 3. Automotive paint Reflective powder is often added in automotive paint. It has a protective effect. It can improve the safety of vehicles running at night. What are the precautions for using reflective paint? 1. Thoroughly remove oil stains, water stains and dust on the substrate surface before construction. Keep the working surface dry. 2. Fully mix the reflective primer and reflective paint before use. Stir them constantly during construction. 3. First apply our reflective primer. When the reflective primer is dry, spray reflective paint. Preferably, spray two layers of reflective primer on cement. 4. The paint film should be even and thin. Its thickness should be about 20 microns. Otherwise, the effect will be poor.

Saat kemasan fleksibel dan lini konversi berkecepatan tinggi mendorong efisiensi yang lebih besar, pengendalian gesekan telah muncul sebagai parameter kualitas yang tidak dapat ditawar. Para pakar industri menunjukkan bahwa lilin PTFE termikronisasi merupakan aditif pilihan utama untuk mencapai koefisien gesekan (COF) yang rendah secara konsisten tanpa mengorbankan kualitas cetak. Dalam formulasi tinta cetak modern, koefisien gesekan jauh lebih dari sekadar metrik laboratorium—parameter ini secara langsung menentukan seberapa lancar film, foil, dan kertas bergerak melalui penggulung ulang, penyegel, pemotong, dan pengisi. Ketika COF terlalu tinggi, konverter menghadapi serangkaian masalah mahal: lapisan yang saling menempel pada gulungan, goresan permukaan, pengumpanan yang tidak stabil, dan penghentian lini yang sering terjadi. Sebaliknya, gesekan yang terlalu rendah dapat menyebabkan masalah registrasi atau selip tumpukan. Oleh karena itu, menemukan keseimbangan yang tepat merupakan tantangan utama dalam formulasi. Lilin polytetrafluoroethylene (PTFE) termikronisasi telah mendapatkan perhatian sebagai solusi yang sangat efisien untuk menurunkan COF dalam sistem tinta berbasis pelarut maupun berbasis air. Kimianya yang unik—ditandai dengan energi permukaan yang sangat rendah—memungkinkan partikel halus berpindah menuju permukaan lapisan tinta selama pengeringan atau pengawetan. Di sana, partikel tersebut membentuk lapisan pelumas ultratipis yang tidak kontinu, yang secara drastis mengurangi hambatan geser sambil mempertahankan daya rekat dan sifat mekanis yang mendasari. Melampaui kelicinan: ketahanan terhadap pemblokiran dan abrasi Manfaatnya melampaui sekadar peningkatan kelicinan. Dalam kemasan fleksibel, di mana lembaran cetak digulung dengan tegangan tinggi dan disimpan selama berhari-hari atau berminggu-minggu, kinerja anti-pemblokiran sangat penting. Lilin PTFE meminimalkan daya rekat antara lapisan yang berdekatan, sehingga mencegah cacat gulungan yang mahal. Secara bersamaan, efek pelumasan yang sama mengurangi goresan dan abrasi selama transportasi, memastikan kemasan akhir sampai kepada pemilik merek dengan grafis yang tetap sempurna. Memilih tingkat PTFE yang tepat Tidak semua lilin PTFE memiliki kinerja yang sama. Formulator harus mengevaluasi ukuran partikel, kualitas dispersi, dan kompatibilitas resin untuk mencapai hasil optimal. Tingkat termikronisasi halus—biasanya dalam kisaran 3–6 µm—menghasilkan permukaan yang lebih halus dan kejernihan yang lebih baik, yang sangat dihargai dalam pencetakan definisi tinggi pada film transparan. Kompatibilitas dengan pengikat poliester, poliuretan, nitroselulosa, dan akrilik juga sama pentingnya untuk kestabilan viskositas dan peletakan tinta yang konsisten. Namun, dosis memerlukan kalibrasi yang cermat. Dosis yang terlalu rendah gagal memberikan penurunan COF yang diinginkan, sedangkan dosis yang berlebihan dapat mengurangi kilap, mengganggu daya rekat antar lapisan, atau menyebabkan penumpu...
