DH-4073 leveling and wetting agent is a unique silicone surfactant for reducing surface tension. The addition amount is small, and a small amount of addition can achieve high performance.
Hydrogen peroxide-metal ion (M leaf) redox initiation system The redox initiation system reacts.
The generated high-valent metal ions [M(n+1)+] react with hydrogen peroxide to reduce to low-valent metal ions.
Commonly used in industry is the combination of cyclohexanone peroxide or msds polyethylene wax methyl ethyl ketone peroxide and cobalt naphthenate. For example, unsaturated polyester with 0.5%~2.0% cyclohexanone peroxide and 0.1%~0.3% cobalt naphthenate mixed initiator can quickly crosslink to form a film at room temperature.
When cobalt naphthenate is used as a reducing agent, adding a small amount of tertiary amine compounds such as N,N-dimethylaniline and or a small amount of ketones (such as acetone) has a significant promoting effect. If a small amount is added, it is easy to form a complex with cobalt ions. Some compounds, such as water, free glycols or certain other metal salts, will cause a decrease in the initiation efficiency. When there is a small amount of manganese naphthenate in the system, the curing speed is significantly reduced.
