Microcrystalline wax is a high-melting-point, fine-crystalline wax refined from petroleum fractions. Compared to common paraffin wax, its key properties make it exceptionally well-suited for electronic sealing: Fine crystalline structure: Its minute crystals form a dense, resilient wax film with outstanding moisture and water resistance. This is its primary merit as a sealant. High melting point and viscosity: Typically melting between 60°C and 90°C, its elevated softening point ensures superior thermal stability, resisting softening and migration in elevated temperatures. Excellent adhesion and flexibility: Adheres effectively to diverse material surfaces while maintaining crack resistance at low temperatures. Superior electrical insulation: Inherently an excellent insulating material, preventing short circuits.

Oxidised polyethylene wax is a versatile polymeric material with extensive applications across plastics, coatings, inks and other sectors. Its unique lubricating properties enable it to play a significant role in these fields. Specifically, the lubricating effect of oxidised polyethylene wax manifests primarily in reducing the coefficient of friction between materials, enhancing processing fluidity, and improving product surface gloss. During plastic processing, oxidised polyethylene wax can serve as an internal lubricant. It is compatible with plastic resins, reducing intermolecular friction in the molten state to enhance melt flow and processing properties. In the coatings and inks sector, polyethylene oxide wax is predominantly employed as an external lubricant. In these applications, it forms a smooth film on the surface of coatings or ink layers, minimising friction between the coating and substrate or between multiple coating layers.

The primary functions of micro-wax in powder coatings: 1. Scratch and abrasion resistance Mechanism: During baking and curing, wax particles migrate to the coating surface, forming a thin, dense protective layer. This wax film possesses a low coefficient of friction and excellent lubricity, effectively reducing surface scratches and wear. Applications: Widely employed in sectors demanding high surface durability, such as household appliances (e.g., refrigerator and washing machine panels), aluminium extrusions, outdoor furniture, and automotive components. 2. Enhanced Flow and Hand Feel (Slipperiness Enhancement) Mechanism: Wax particles suspended on the surface render the coating smoother, not only reducing friction but also imparting a refined, silky- smooth tactile quality. Application: Products requiring specific tactile properties, such as electronic casings and office furniture. 3. Anti-adhesion (anti-caking) Mechanism: Micronised wax forms a micro-irregular ‘orange peel’ texture on the coating surface or provides physical separation. This reduces direct contact areas between coatings or between coatings and other surfaces, preventing adhesion during stacking or transportation. Applications: Critical for products requiring stacked storage, such as metal sheets and pipes.

They help in clearing up any remaining adhesive to ensure clean, precise finishes in assembly lines. 4. Cleaning in Automotive Manufacturing: In automotive industries, where PUR- based coatings or foams are used for insulation, padding, or sealing, specialized PUR cleaning agents help maintain production equipment by ensuring it is free from stubborn residues that could affect subsequent processes. 5. Cleaning of Tools and Applicators: When using PUR adhesives, cleaners are essential for clearing out guns, nozzles, or tools to avoid clogs and ensure smooth operation in subsequent uses. PUR cleaning agents offer an efficient and non-abrasive way to clear these tools without causing damage. 6. General Maintenance Cleaning: PUR cleaning agents are also used for routine maintenance in various industrial environments, including cleaning of spills or mishaps during the manufacturing of products that use polyurethane components. They help minimize waste and prevent potential damage to machinery or working areas. 7. Removal of Cured PUR: For difficult-to-remove, cured PUR from manufacturing or repair processes, cleaning agents formulated specifically for PUR offer an effective solution. These cleaners can dissolve hardened residues, making it easier to remove or rework affected areas.

Oxidised polyethylene wax may be employed in rust prevention applications. The polar functional groups on its molecular chain, such as carbonyl and hydroxyl groups, enhance adhesion to metal surfaces and protective performance in rust prevention applications. When incorporated into coatings or rust inhibitors, it forms a dense wax film upon cooling. This film exhibits excellent scratch resistance and effectively seals out moisture and oxygen, thereby achieving rust prevention.

Micronized wax particles form a microscopic ‘protective layer’ by floating on or protruding from the coating surface, thereby performing the following key functions: 1. Scratch resistance and abrasion resistance Mechanism: Wax particles are uniformly distributed within the coating, with some remaining exposed on the surface after curing. These hard particles withstand scratching forces from external objects, effectively shielding the underlying paint film. Application: Widely employed in sectors requiring frequent friction or contact, such as construction machinery, automotive OEM/touch-up paints, industrial flooring, and container coatings. 2. Enhanced Surface Smoothness and Tactile Feel Mechanism: Wax particles reduce the surface friction coefficient, minimising resistance when objects glide across the coating and imparting a smoother sensation. Simultaneously, they confer a refined, dry-to-the-touch finish. Applications: Products demanding superior surface tactility, such as electronic casings, domestic appliances (washing machines, refrigerators), and furniture wood finishes.

Micronized wax primarily functions as a processing aid and modifier in engineering plastics, with its core properties as follows: 1. Lubrication represents micro-wax's principal function, categorised into internal and external lubrication. Internal lubrication: Wax molecules disperse within the plastic melt, reducing friction between polymer chains and thereby lowering melt viscosity. External lubrication: Wax molecules migrate to the interface between the melt and processing equipment (such as moulds and screws), forming a lubricating film. Improved demoulding properties facilitate easier removal of products from moulds, reducing scrap rates. Enhanced surface finish yields smoother, more lustrous products. 2. Significant wear resistance and anti-slip properties When incorporated into engineering plastics, micronized wax forms a micro- lubricating layer on the product surface, lowering the surface friction coefficient. Application examples: Components requiring frequent motion and friction, such as gears, bearings, sliders, and guide rails, benefit significantly from micronized wax addition, which substantially extends their service life.
