Polyurethane Adhesives Buying Guide

Due to their long-lasting, strong bonding properties, polyurethane adhesives are widely used to make insulating foams and mattresses. This is the primary reason for its increased usage for a vast number of different applications. Other types of security instruments are entirely unnecessary as they can seal thoroughly without requiring clamps. The car industry uses polyurethane adhesive mainly because it is suitable for vehicle interiors and to bond windshields. Amazingly, it does not break down when exposed to outdoor elements and is a perfect dispensing tool that fits.

Durable and Flexible

Polyurethane adhesives that are strong to seal fuel tanks as it is amazingly flame-resistant. Nowadays, it is used by the home construction industry that includes many types of substrates like plastic, wood, glass, and concrete. The varying degree in which it offers resistance to heat and chemicals makes it the famous adhesive offering bulk flexibility—formed by the reaction of polyol and isocyanate that powers the strong bond of chemicals.

Advantages of Polyurethane Adhesives

Tests have already shown that the adhesives are advantageous, and compared to PVA glues, they are remarkably more robust. Due to their toughness, they are often used on boats. The specialized feature is that a little sun and rain cannot do any harm at all. As they are weather-resistant, they are suitable for outdoor projects. There are varieties of polyurethane adhesives, and each depends on the excess of the work required.  Once it is set, it does not melt when heated.


Some of the polyurethane adhesives are only water-resistant and not 100% waterproof. Usually, it is not recommended to use during heavy rainfall due to its low susceptibility. With no foam and easy to use instructions, it is better to choose one with clear instructions. Best for severe repairs on different surfaces, it is ideal for indoors and outdoors. As an incredibly strong adhesive, it can expand three times into the materials and form a strong bond.
