1. decrement when heating: ≤3%(65°C)
 2. ash content: ≤1%(1000°C)

　　1. As a kind of slow accelerating agent, the product can be used for promoting cross-linking density of rubber product and increasing brightness of color product.
　　 2. Having been made moisture-proof and electrostatic prevent treatment, the product is made into a kind of particle with its fine dispersing performance, it can be used to obviously solve the defective problem of moisture absorption, deliquation and lumping of accelerating H powder.
　　 3. As a kind of accelerating agent, it can be used with other kind ones together and no blooming.
　　 4. It is a kind of particle product, so it is easy to be correctly measured and is an ideal product for bettering production conditions according to the requirements for materials' safety and environmental protection.
　　 5. It is often used together with resorcinol in rubber and metallic adhesive composition as a formaldehyde donor.

　　As an accelerating agent, the amount for application is usually 0.5~5 phr.
　　As an adhesive used in resorcinol and formaldehyde composition, the amount is usually 1.3~1.6 phr of this kind of product with 2.5~3.2 phr of resorcinol.

The product can be stored in a shady, cool and dry place for one year.
