Sodium Gluconate As a Set Retarder For Concrete
Isocyanates are a family of highly reactive, low molecular weight chemicals. They are widely used in the manufacture of coatings such as paints and varnishes, and elastomers, and are increasingly used in the automobile industry, autobody repair, and building insulation materials. Spray-on polyurethane products containing isocyanates have been developed for a wide range of retail, commercial, and industrial uses to protect concrete, wood, plastics, and metals.
