characteristic
Excellent chemical stability. This product has the advantages of stable acid value, stable molecular weight, light color, and good catalytic effect, and can completely replace potassium naphthenate. The solubility of solutes belongs to total solubility. This product is a universal sodium salt agent used for the synthesis of antibiotic solvents. Compared with the traditional salt forming agent sodium acetate, its obvious advantages lie in its gentleness and stability after salt forming, and it can be dissolved in many organic solvents, which is conducive to the separation of anhydrous final products and improves the quality and yield of products.
Usage:
K-15 is usually a solid and is usually dissolved and diluted with diethylene glycol to form a solution;
K-15 is suitable for use in high viscosity polyol formulations to promote isocyanate reactions with high activity;
K-15 is widely used in spraying hard foam, PIR hard foam and other kinds of PU hard foam.
Mainly used as a salt forming agent for the synthesis of cephalosporin antibiotics, a crosslinking agent for polymer materials, a heat stabilizer for plastic products, a catalyst for polymerization reactions, and an additive for lubricating and fuel oils. In the polymerization process of polyester resin system, promoting the catalysis of cobalt soap effectively reduces the amount of cobalt used; It can also be used to make dyes, spices, preservatives, etc.
Application:
Polyurethane hard foam trimerization catalyst with high activity, suitable for spraying, hard foam, PIR hard foam, PU hard foam. It is recommended to add 3-5 PPHP (per 100 parts of polyols)
Storage and transportation:
Should be sealed and stored in a dry, cool, and ventilated warehouse
Packaging:
200KG/barrel storage: It is recommended to store in a dry and cool area with appropriate ventilation. Please tighten the packaging cover as soon as possible after the original packaging to prevent water ingress and other substances from affecting product performance. Do not inhale dust and avoid contact with skin and mucous membranes. Smoking, eating, and drinking are prohibited in the workplace. After work, take a shower and change clothes.
