Polyurethane adhesive is a water-resistant glue used in bookbinding and woodworking. Different chemical combinations give rise to different properties, such as stiffness, density, and hardness. The adhesive was first developed in 1985 and has undergone several improvements, with the fourth generation having a low viscosity, high solidity, and curing time of a few seconds. It […]
Polyurethane insulation is a closed cell material that resists heat transfer, reduces air pollutants and mold growth. There are three types: MEPS, XEPS, and liquid foam. MEPS and XEPS can be laminated with coatings and used in construction or refrigeration. Liquid foam expands to fill small spaces and is moisture and flame resistant. Polyurethane insulation […]
Polyurethane mastic is a versatile sealant that can adhere to various surfaces, including wood. It has a long-lasting application and can stretch to accommodate expanding and contracting materials. However, it can be sticky, stiff, and toxic, making it less practical for interior modifications. It may require protective materials during application and solvent-based cleaners for cleaning. […]
Polyurethane is a versatile organic compound used as a sealant, adhesive, and coating due to its resistance to moisture, chemicals, and corrosion. It is flexible and available in one or two-component compounds, with water-based options now available. It adheres to various materials and is effective as a wood finish or metal anticorrosive. Proper application is […]
Polyurethane resin is a versatile material used in the production of various products. It is made by reacting polyols and diisocyanates with heat or catalysts. The material can be manipulated to change properties and is resistant to chemicals and abrasion, but can be affected by sunlight and organic solvents. Polyurethanes are a highly variable family […]
Polyurethane is a versatile material that can replace various substances in different industries. It’s made by combining diisocyanate and diol, resulting in a base material that can be liquid, foam or solid. Polyurethane can be elastic or stiff, making it useful in various applications such as cart wheels and airport seats. It’s also used to […]
Polyurethane adhesives are strong and versatile, able to bond a variety of materials regardless of porosity. They are resistant to water, extreme temperatures, and chemicals, making them ideal for building applications and bookbinding. Available in household, gel, and heavy-duty forms. Polyurethane refers to any polymer made up of repeating chains of organic units joined by […]
Polyurethane foam is a low-density material that can be flexible or rigid and has many applications, including in bedding, upholstery, insulation, automobile interiors, construction, and as a spray-on material. It is versatile and customizable, but care must be taken when applying it due to potentially harmful fumes. Polyurethane foam refers to a number of different […]
