2) Application: Blocked isocyanate crosslinker

In water based parquet lacquers to improve water ,alcohol,detergent Chemical and abrasion resistanceIn water based industrial wood-,plastic-and metal coatings to increase water ,alcohol and block resistance

In vinyl coatings to reduce plasticizer migration and improve stain resistanceIn water based concrete sealers to improve abrasionResistance

Generally,to improve adhesion of water based systems to non-polar substratesIn solvent based polymers to increase resistance propertiesIn water based printing inks to improve water and detergent resistance

3) Formulating guidelines:

Raw material for coatings, adhesives, sealants, or elastomers in industrial applicationsApplicable to waterborne resin systems, such as waterborne acrylate and waterborne polyurethane, to improve the adhesion, strength and hardness of the coating. It can be prepared with resin as a single component system. The performance of the film depends on the treatment technology, the amount of crosslinking agent and the hydroxyl value of the system.

4)Handling
Care must be taken to avoid any contact with the skin and eyes. When used in spray applications, particular care must be taken to avoid oral and/or nasal ingestion by wearing a suitable respirator. When handling C-100 it is desireable to prevent inhalation of vapours by proper ventilation or respirator use.
5)Package and StorageAvailable 4*5Kgs plastic pails per Carton ,25Kgs Plastic lining steel drum . Store in a cool, dry, dark place. If stored under conditions of excessive heat for extended periods the material may discolour, deteriorate and gel.
