This product becomes milky white when dispersed in water. This product has a non-volatile content (0.9-1.1g / 1h / 125°C, convection oven) of 32-35, a flow time at 23°C, (4mmcup) of 11-18, and a pH value 20°C (supply form) of 6.0-8.0. Baybond® PU 405 was developed for the sizing of glass fibres used to reinforce thermoplastics, particularly polyamide. Glass fibre sizes based on Baybond® PU 405 are characterised by their outstanding film-forming properties and very good adhesion. They have very good colourfastness, even at high temperatures. The mechanical film properties of the product are developed fully by post-crosslinking at temperatures from 170°C for a duration of 20 minutes. Baybond® PU 405 is also highly resistant to shear forces and hydrolysis. view less | |

It can also be used in combination with Desmodur® L and HL in the formulation of fast-drying two-component coatings. This product as a viscosity at 23°C of 3,000 ± 500 mPa·s, a non-volatile content (2g resin/2ml toluene/1h 125°C, convection oven) of 70±1%, and a flash point of approx. 32°C. Desmophen® 680 BA is a hard co-reactant for use with Desmodur® N. The drying properties of this combination are comparable with those of the acrylic Desmophen® resin/Desmodur® N systems developed specially for automotive repair paints. It is therefore particularly suitable for the formulation of air-drying automotive and industrial coatings. Coatings crosslinked with Desmodur® L and HL are particularly fast-drying, making them suitable for applications such as paper finishing. view less | |

It is binder certified for use in food-contact applications for the formulation of can coatings for food packaging. This product has a non-volatile content (2g resin/2ml toluene/1h 125°C/convection oven) of 75 ± 2%, a density at 20°C of approx. 1.08g/ml, and a viscosity at 23°C of 3,700 ± 600 mPa·s. Desmophen T 1775 SN was developed specially as a co-reactant for blocked polyisocyanates in coil coating applications. When combined with preferably Desmodur BL 4265, it yields one-component polyurethane coil coatings with a balanced hardness/flexibility ratio, good resistance to scratching and abrasion as well as excellent QUV/B stability. Dibutyltin dilaurate has proved suitable as the catalyst. The addition should be 0.1–1 %, calculated on the solid binder. The product can be combined with other blocked isocyanates and HMMM-type amino resins.
