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.

As flexible packaging and high-speed converting lines push for greater efficiency, friction control has emerged as a non‑negotiable quality parameter. Industry experts point to micronized PTFE wax as the go‑to additive for achieving consistently low coefficients of friction (COF) without compromising print quality. In modern printing ink formulations, the coefficient of friction is far more than a laboratory metric—it directly dictates how smoothly films, foils, and paper run through rewinders, sealers, cutters, and fillers. When COF is too high, converters face a cascade of costly issues: blocking in wound rolls, surface scratching, erratic feeding, and frequent line stoppages. Conversely, overly low friction can create register problems or stack slippage. Striking the right balance is therefore a primary formulation challenge. Micronized polytetrafluoroethylene (PTFE) wax has gained traction as a highly efficient solution for lowering COF in both solvent‑based and water‑based ink systems. Its unique chemistry—characterised by an exceptionally low surface energy—allows fine particles to migrate toward the ink film’s surface during drying or curing. There, they form an ultrathin, discontinuous lubricating layer that drastically reduces sliding resistance while preserving the underlying adhesion and mechanical properties. Beyond slip: anti‑blocking and abrasion resistance The benefits extend beyond simple slip enhancement. In flexible packaging, where printed webs are wound under high tension and stored for days or weeks, anti‑blocking performance is critical. PTFE wax minimises the adhesion between adjacent layers, preventing costly roll defects. Simultaneously, the same lubricating effect reduces scuffing and abrasion during transportation, ensuring that finished packages reach brand owners with pristine graphics. Choosing the right PTFE grade Not all PTFE waxes perform identically. Formulators must evaluate particle size, dispersion quality, and resin compatibility to achieve optimal results. Fine micronised grades—typically in the 3–6 µm range—yield smoother surfaces and superior clarity, which is especially valued in high‑definition printing on transparent films. Compatibility with polyester, polyurethane, nitrocellulose, and acrylic binders is equally essential for stable viscosity and consistent ink laydown. Dosage, however, requires careful calibration. Under‑dosing fails to deliver the desired COF reduction, while overdosing can dull gloss, impair intercoat adhesion, or cause plate build‑up. Most successful formulations fall within 0.5–3% by weight on total ink solids, but the optimal level varies with substrate, application method, and drying conditions. For instance, BOPP and PE films—common in snack food packaging—often respond well to finer PTFE particles combined with a secondary slip agent. PET films and aluminium foil, on the other hand, may benefit from coarser grades or blended systems that incorporate polyethylene wax, amide wax...

Acrylic resin is a copolymer of butyl methacrylate and methyl methacrylate that is soluble in chlorinated hydrocarbons, esters, glycol ethers, ketones, aromatic, and glycol ether acetates. It is compatible with a wide-ranging variety of other resins including maleinate resins, acrylics, nitrocellulose, vinyl, and chlorinated rubber.

Polyvinyl Butyral (PVB) resin is a water-insoluble thermoplastic polymer known for its excellent binding and film-forming properties. It dissolves readily in a wide range of organic solvents and shows good compatibility with many other polymers. With superior elasticity and optical transparency, PVB suits diverse industrial uses. Both high- and low-viscosity grades are available, with glass transition temperatures tailored to specific applications. Stability can be further enhanced via cross-linking. As a result, PVB serves as a key binder in paints, primers, adhesives, metal powders, and ceramics, as well as an interlayer in laminated safety glass, making it indispensable across multiple industries. Field of Application: Wash Primer PVB-based "wash primer" is widely used on metal surfaces such as storage tanks, ships, aircraft, bridges, dam locks, and electronic appliances. Compared to conventional materials, it offers superior corrosion protection, better adhesion, faster drying, and easier application. Strong anchoring is achieved through a complex interaction of synthetic resin, pigments, phosphoric acid, and metal ions.   Foil Coatings Applying PVB solution onto metal foils (e.g., aluminum, brass, tin, lead, iron) improves mechanical strength, moisture resistance, and printability. Adhesion can be further enhanced by stoving at up to ~140°C.   Wood Paints PVB is widely used in wood sealers and topcoats, imparting toughness, flexibility, and impact resistance. Common blends include PVB with phenolic resins, shellac, or nitrocellulose. As a knot sealer, it prevents terpene and resin bleeding.   Leather Paints Combined with nitrocellulose and plasticizers, PVB provides excellent adhesion, high elongation, and crack prevention while maintaining leather flexibility.   Stoving Paints Blends of PVB with phenolic, melamine, or urea resins are ideal for stoving paints. Adding 5–25% PVB to phenolic resin transforms a brittle film into one with good flexibility, excellent leveling, a pinhole-free surface, and improved alkali resistance.   Powder Coatings PVB blended with epoxy resins improves edge covering and prevents pulverization.   Adhesives PVB-phenolic mixtures bond metal, glass, leather, wood, fabric, paper, and more. After solvent removal, surfaces are heated and pressed together. Typical curing: 160°C for 15–30 minutes.   Printed Circuit Board Adhesives A PVB-phenolic blend meets key PCB adhesive requirements: high peel strength, blister resistance, and good dielectric properties, ideal for bonding phenolic prepregs to copper foil.   Printing Inks PVB is used in gravure, letterpress, and flexographic inks, offering flexibility, strong adhesion, and toughness.   Hot-Melt Adhesives Fusing PVB with plasticizers and fluxing resins produces hot-melt adhesives that form tough, clear films with good adhesive strength.   Ceramic Binders In ceramic electronic components, PVB acts as a binder, providing ...
