Desmophen® NH 1521
Covestro (formerly Bayer MaterialScience) 科思创
Desmophen® NH 1521 is an amino-functional co-reactant for polyisocyanates, and is used for the manufacture of high-solids, two-component polyurethane coating formulations. This product has an amine number of 168-176mg KOH/g, a solvent content (GC method) of 9-11%, and an equivalent weight of approx. 326. Desmophen® NH 1521 is a reactive thinner which is suitable, either alone or in combination with suitable OH-functional polyacrylates and cured with e. g. Desmodur® N 3600 or N 3390, for the formulation of high-solids primer fillers and topcoats for automotive refinishing applications.

Baybond® PU 330
Baybond® PU 330 is an anionic, non-ionic polyester urethane polymer, used as the film-forming component in glass fibre sizes. Baybond® PU 330 is commonly used as the film-forming component in glass fiber sizing, especially for glass fibers used to reinforce thermosets. Glass fiber sizes based on Baybond® PU 330 have excellent film-forming properties and adhesion. This product also remains stable when exposed to shear forces. As with any product, use of Baybond® PU 330 in a given application must be tested (including but not limited to field testing) in advance by the user to determine suitability.
Baybond® PU 403
Baybond® PU 403 nionic, non-ionic polyester urethane polymer, used as the filmforming component in glass fibre sizes. It becomes milky white when dispersed in water. This product has a non-volatile content (0.9-1.1g / 1h / 125°C, convection oven) of 39 ± 1, a flow time at 23°C, (4mmcup) of 11-18, and a pH value at 20°C (supply form) of 6.0-8.0.
Baybond® PU 405
Baybond® PU 405 is an anionic/non-ionic crosslinking polyether urethane polymer used as the film-forming component in glass fibre sizes. 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.
Baybond® PU 406
Baybond® PU 406 is a non-ionic polyurethane polymer used as the film-forming component in glass fiber sizes. This product displays a milky white dispersion in water. It has a non-volatile content (0.9-1.1g / 1h / 125°C, convection oven) of 34.5 ± 1.5, a flow time at 23°C, (4mmcup) of 10-22, and a pH value at 20°C, (supply form) of 5.5-7.5.
