Baybond® XL 825 Covestro Baybond® XL 825 is a waterbased aliphatic blocked polyisocyanate that is suitable for use as a crosslinker for glassfiber sizings. This product non-volatile content (0.9 - 1.1g / 1h / 125°C,convection oven) 30 ± 1, a flow time at 23°C, (4mmcup) of 10 - 5...voir plus Baybond® XL 825 is a waterbased aliphatic blocked polyisocyanate that is suitable for use as a crosslinker for glassfiber sizings. This product non-volatile content (0.9 - 1.1g / 1h / 125°C,convection oven) 30 ± 1, a flow time at 23°C, (4mmcup) of 10 - 55 , and a pH value at 20°C (supply form) of 7-8. Baybond® XL 825 was developed as crosslinker for the sizing of glass fibers used in combination with Baybond binders to reinforce thermoplastics, particularly polyamide. Glass fiber sizes based on Baybond® XL 825 are characterized by their good colorfastness, even at elevated temperatures. The mechanical film properties of sizings based on Baybond® XL 825 are developed fully by postcrosslinking at temperatures from 170°C for a duration of 20 minutes. The product is compatible with the additives normally used in the formulation of glass sizes, e.g. adhesion promoters, lubricants, antistatic agents and plasticizers. voir moins
Desmodur® BL 3272 MPA Covestro Desmodur® BL 3272 MPA is a blocked aliphatic polyisocyanate based on hexamethylene diisocyanate (HDI) and dissolved in propylene glycol monomethyl ether acetate(MPA/PMA).

It was developed as a hardener for lightfast one-pack baking polyurethane coatings whose baking temperature can be reduced by the addition of a catalyst, e.g. 0.3 - 1.0 % DBTL, without influencing the storage stability of the ready-to-use formulation. voir moins
Desmodur® BL 3370 MPA Covestro Desmodur® BL 3370 PMA is a blocked aliphatic polyisocyanate based on hexamethylene diisocyanate (HDI) and dissolved in propylene glycol monomethyl ether acetate(MPA/PMA).

It is used with hydroxyl functional coreactants in the formulation of light-stable one-component baking systems with relatively low curing temperatures. Coatings based on Desmodur® BL 3370 MPA are used for the industrial finishing of appliances, coil coating, can coating, and in the automotive industry for chip-resistant primer-surfacers and topcoats. voir moins
Desmodur® BL 3475 BA/SN Covestro Desmodur® BL 3475 BA/SN is a blocked aliphatic polyisocyanate based on hexamethylene diisocyanate (HDI) and isophorone diisocyanate (IPDI) and dissolved in n-butyl acetate and aromatic 100 (1:1). It was developed as a hardener for lightfast one-pack bakin...voir plus Desmodur® BL 3475 BA/SN is a blocked aliphatic polyisocyanate based on hexamethylene diisocyanate (HDI) and isophorone diisocyanate (IPDI) and dissolved in n-butyl acetate and aromatic 100 (1:1). It was developed as a hardener for lightfast one-pack baking polyurethane coatings with a low baking temperature. Used in the formulation of high-quality industrial coatings, especially for cans and tubes. The product can also be used as an additive to improve the reactivity, flexibility and adhesion of conventional baking systems. voir moins
